INTRODUCTION Thank you for purchasing an Eagle sonar. Your Magna or Magna III Plus is a high quality sonar designed for both professional and novice fishermen. These units have an automatic feature that finds and displays the bottom, fish, structure, and more! All you have to do is press the on key. However, if you wish to fine tune the unit, all you have to do is press the menu key. The Magna series has powerful features available through easy-to-use menus. To get started with your Eagle unit, first read the installation section. This is where it all begins. Improper installation can cause problems down the road. After youve read the instructions, install the unit, then read the rest of the manual. The more you know about your unit, the better it will perform for you.

INSTALLATION - Bracket You can install the Magna III on the top of a dash or from an overhead with the supplied bracket. It can also be installed in the dash with an optional IDA-3 mounting kit. If you use the supplied bracket, you may be interested in the optional GBSA-1 swivel bracket kit. This converts the Magna III's gimbal bracket to a swivel mount which can be used on the dash or overhead mounting positions. Installation instructions for the in-dash and swivel mounting kits are supplied with the adapter kits. Mount the Magna III in any convenient location, provided there is clearance when its tilted for the best viewing angle. Holes in the brackets base allow wood screw or through bolt mounting. It may be necessary to place a piece of plywood on the back side of thin panels to reinforce the panel. Make certain there is enough room behind the unit to attach the power and transducer cables. Drill a hole in the dash for the power and transducer cables. The best location for this hole is immediately under the gimbal bracket. This way, the bracket covers the hole. The smallest hole the Magna IIII's power and transducer cable connectors can pass through is 3/4". However, you cant pass a power or transducer connector and another cable through a 5/8" hole. Therefore, after drilling the hole, pass the transducer connector up through the hole from under the dash. Then drop the power cable down from the front side of the dash. After installing the transducer, route its cable to the unit by passing it through the hole from under the dash. Slide the bracket over the hole, then route the transducer and power cables out the slot in the back of the bracket. Finally, fasten the bracket to the dash.

Attach the Magna III to the gimbal bracket using the supplied gimbal knobs and washers as shown above.
POWER CONNECTIONS The Magna III works from a 12 volt DC system only. For the best results, run the power cable directly to the boats battery. Keep the power cable away from other boat wiring, especially the engines wires. This will give the best isolation from electrical noise. If the supplied cable is not long enough to reach the battery, splice #18 gauge insulated wire to it. If you do extend the power cable, make certain to attach the in-line fuse holder supplied with the Magna III to the battery or power source. This will protect both the unit and the power cable in the event of a short. Use only a 3-amp fuse. You can also attach the power cable to an accessory or power buss, however, you may have problems with electrical interference. These units have reverse polarity protection. No damage will occur if the power wires are reversed. However, the unit will not work until the wires are attached correctly.

SPEED/TEMPERATURE SENSOR INSTALLATION (Magna III Plus Only) Mount the speed/temp sensor on the boats transom in a location where the flow of water is the smoothest. There should be a minimum of turbulence and air bubbles in the chosen location. The port (left) side of the transom is preferred, however, the starboard (right) side can be used if necessary. Do not mount the speed sensor behind strakes, ribs, or thru-hull fittings. These will disturb the flow of water to the speed sensor. In a typical installation, the speed sensor is mounted six to twelve inches from the centerline of the hull. The sensor must always be in the water to function properly. Make certain the chosen location is in the water even at high speed or when the boat is on plane. Once you determine the proper location, place the sensor on the transom. Make certain the sensors bottom is flush with the bottom of the hull. Mark the transom in four places, two in each slot. Drill a 5/32" mounting hole at each location. Mount the sensor to the hull with four #10 stainless steel screws. Use a good grade of caulking compound to seal the screws. Adjust the sensor so it is flush with the bottom of the hull and tighten the screws. If the base of the transom has a radius, fill the gap between the transom and the sensor with caulking compound. This will help ensure a smooth water flow. Route the sensor cable to the in-line connector on the Magna Plus power cable. The speed/temp sensor is now ready for use.

MAGNA III PORTABLE ASSEMBLY INSTALLING THE BATTERIES Release the latch on the front of the battery case. Open the compartment and install four "D" cell batteries into the adapter. For the longest life, we recommend you use alkaline batteries. This battery case will also hold one rechargable battery instead of the "D" cells. See the enclosed coupon for more information on the rechargable battery.
"D" CELL BATTERY
After installing the batteries, close the case and plug the power cable on the battery case into the Magna III Portable. Plug the adapter cable into the back of the sonar unit. Turn the sonar unit on. If it doesn't work, make certain the battery terminals are making good contact against the battery contacts. Also check the wiring connections on the D-cell battery adapter. The red wire on the power cable should be attached to the red wire on the D-cell battery adapter and the power cable's black wire should be connected to the black wire on the D-cell battery adapter. If it still doesn't work,
check the battery voltage. Most of the complaints we receive about portable units result from stale batteries. Make certain the ones you buy are fresh. Always remove batteries from the battery compartment before storing the unit as dead batteries can leak and corrode the contacts. In cold weather the efficiency of dry cell batteries drops with the temperature. We find it a good idea to have the Magna III Portable good and warm along with the batteries before we leave home. If the batteries do lose a charge, you can sometimes restore them by placing them in a warm room or car interior. A better way is to replace them with batteries that have been kept warm. Don't ever heat the batteries over an open flame or direct hot air onto them. A fire or explosion could result.
PORTABLE TRANSDUCER ASSEMBLY Assemble the transducer and bracket as shown below. Attach the transducer to the bracket with the supplied hardware. Make certain there is one washer on each side of the transducer, inside the bracket. Slide the other washer over the end of the bolt and thread the nut onto it. Screw the suction cup onto the bracket using the supplied screw and flat washer. Tie the nylon cord through the hole in the top of the bracket. When using this transducer, tie the other end of the nylon cord to the boat. This will help prevent the loss of the transducer if it comes off the boat.

BOLT WASHER

WASHER
Clean the chosen area of the hull before attaching the suction cup. Locate the transducer on the hull as shown below. Don't allow the bracket to go below the hull, as water pressure against it can cause the suction cup to come off at speed. Moisten the cup, then press it onto the hull as firmly as possible. Tie the nylon cord to the boat and route the transducer cable to the sonar unit. Plug the transducer connector into the "Y" power cable on the Magna III. Your portable sonar is now ready for use.
PERMANENT MOUNT TRANSDUCER INSTALLATION The HS-WSBK supplied with your Magna III is a transom mount transducer. It can be installed on any outboard or stern-drive (inboard\outboard) powered boat. It can also be permanently installed inside the boat to "shoot-through" the hull on some fiberglass boats. The kick-up mounting bracket helps prevent damage if the transducer strikes an object while the boat is moving. If the transducer does kickup, the bracket can easily be pushed back in place without tools. Read the enclosed transducer installation manual carefully before attempting the installation. Determine which of the mounting positions is right for your boat. Use extreme care if mounting the transducer inside the hull, since once it is epoxied into position, the transducer usually cannot be removed. Remember, the transducer location is the most critical part of a sonar installation. If it isnt done properly, the sonar cant perform at its designed potential.
KEYBOARD BASICS The unit sounds a tone when you press any key. This tells you the unit has accepted a command. ON/CLEAR Use this key to turn the unit on. It also clears menu selections and the menus from the screen. OFF This key turns the unit off. MENU The Magna III and Magna III Plus have many features that are accessed with this key. To see the first menu, press the MENU key. To see the other menus, press the MENU key repeatedly. UP and DOWN ARROWS Use these keys to adjust virtually every feature and function on the unit. NOTE: The up arrow key also stops the chart when no menus are displayed. In other words, anytime you wish to stop the chart, first make certain no menu is on the screen. Now press the up arrow key. The chart freezes and the word STOP appears at the top of the screen. To start the chart, press the up arrow key again. DISPLAY - General The lights flash for about ten seconds when the Magna III is turned on. Three menus appear, one after the other. The menus are the lights (LAMP), feet-meter selection (FEET/METER), and contrast adjustment (DARK/LIGHT). To turn the lights on, press the up arrow key. To switch from feet to meters, press the down arrow key when the proper menu appears. To adjust the contrast, wait for the DARK/LIGHT menu to appear. Now press the up arrow key to darken the screen, the down arrow to lighten it. The menus disappear after a few seconds. If you dont want to wait, press the ON/CLEAR key to clear the menus from the screen. When the Magna III is first turned on, the display appears similar to the one at right. The unit is in the automatic mode and the Fish

GRAYLINE Grayline lets you distinguish between strong and weak echoes. It paints gray on targets that are stronger than a preset level. This shows the difference between a hard or soft bottom, large fish versus smaller ones, or rocks and brush on the bottom. For example, a soft, muddy, or weedy bottom returns a weaker signal which shows a narrow or no gray line. A hard bottom returns a strong signal that causes a wide gray line. If you have two targets of equal size, one with gray and the other without, the target with gray is the stronger echo. This helps distinguish fish from structure, or the larger fish from a smaller one.
Grayline is adjustable. Since it shows the difference between strong and weak echoes, changing the level may require a different sensitivity setting. To change the Grayline level, first press the MENU key until the Grayline menu appears. Now press the up arrow key to increase the level, the down arrow to decrease it. The percentage of Grayline now in use shows in this menu. Echoes scrolling onto the screen will also show the effects of the Grayline change. If you reach the maximum or minimum level, a tone sounds alerting you to the limits. The level chosen by the Magna III when its first turned on is usually adequate for most conditions. Experiment with your unit to find the Grayline setting thats best. FISH ID FEATURE The Fish ID feature identifies targets that meet certain conditions as fish. The microcomputer analyses all echoes and eliminates surface clutter, thermoclines, and other undesirable signals. In most instances, remaining targets are fish. The Fish ID feature displays symbols on the screen in place of the actual fish echoes. There are four symbol sizes: tiny, small, medium, and large. These show the relative size between targets. In other words, it displays a small fish symbol when it thinks a target is a small fish, a medium fish symbol on a larger target, etc. The microcomputer is sophisticated, but it can be fooled. It can't distinguish between fish and other suspended objects such as turtles, submerged floats, air bubbles, etc. Individual tree limbs extending outwards from a group of limbs are the hardest objects for the Fish ID feature to distinguish from fish. You may see Fish ID symbols on the screen when, in fact, there are no fish. Practice with the unit when the Fish ID feature is on and off to become more familiar with Fish ID. When the Magna III is first turned on, the Fish ID feature is automatically turned on, also. To turn this feature off, press the menu key until the Fish ID features menu appears as shown at right. Now press the down arrow key. This turns the feature off. To turn it back on, repeat the above steps, but press the up arrow key instead.
The Fish ID feature cant be used when the Magna III is in the manual mode. If you turn the automatic feature off, the Fish ID feature will automatically be turned off, also. FISH TRACK The Magna III automatically displays the depth of a target when the Fish ID feature places a fish symbol on the screen as shown below. This feature is automatically enabled when the Magna III is turned on. To turn it off or on again, press the MENU key repeatedly until the Fish Track menu appears as shown below. Now press the down arrow key to turn it off. Remember, Fish ID must be on in order to use the Fish Track feature.

CHART SPEED The rate echoes scroll across the screen is called the chart speed. Its adjustable by pressing the menu key until the chart speed menu appears. Chart speed is set to maximum when the Magna III is first turned on. To decrease it, press the down arrow key. Press the up arrow key to increase the speed again. The percent numbers in the Chart Speed menu box shows the speed. Echoes scrolling onto the screen will also show the effects of the change. If you reach the maximum or minimum level, an warning tone sounds. To stop the chart, first clear any menu from the screen by pressing the ON/CLEAR key. You cant stop the chart while a menu is displayed. Now press the up arrow key. The chart will freeze and the word STOP appears at the top right portion of the screen. To start the chart, press the up arrow key again.
DISPLAY MODE The Magna III has three different screen modes. The Magna III Plus has six. To change modes, press the MENU key until the DISP MODE (Display Mode) menu appears. Then press the up or down arrow keys until the desired mode number appears. The modes are as follows:
MAGNA III ONLY CHT 1 (Chart #1) This is the default mode used when the Magna III is first turned on. It has the following features: 1. Automatic On 2. Fish ID Feature On 3. Digital Depth Display On
CHT 2 (Chart #2) This is the High Speed Scroll mode. It shifts the chart speed into high gear, scrolling echoes at a high rate. It has the following features: 1. Automatic Off 2. Fish ID Feature Off 3. Digital Depth Display Off
DIG 1 (Digital #1) This is the digital only screen. It shows the digital depth display at the top of the screen in very large numbers. The shallow and deep alarm settings are displayed beneath the digital depth. No chart shows on this screen.
DISPLAY MODE - MAGNA III PLUS ONLY CHT 1 (Chart #1) This is the default mode used when the Magna III Plus is first turned on. It has the following features: 1. Automatic On 2. Fish ID Feature On 3. Digital Depth Display On
CHT 2 (Chart #2) Same as Chart #1 plus digital surface water temperature display.
CHT 3 (Chart #3) Same as Chart #1 plus digital speed display.
CHT 4 (Chart #4) This is the High Speed Scroll mode. It has the following features: 1. Automatic Off 2. Fish ID Feature Off 3. All Digital Displays Off
DIG 1 (Digital #1) This is the first digital only screen. It shows the digital depth display at the top of the screen in very large numbers. The shallow and deep alarm settings are displayed beneath the digital depth. No chart shows on this screen.
DIG 2 (Digital #2) The digital depth display shows at the top of this screen in very large digits. The digital temperature, speed, and log shows beneath the depth. The log starts counting when the Magna III Plus is first turned on. When the Magna III Plus is turned off, the log is reset to zero.

ALARMS FISH ALARM The Fish Alarm sounds a tone when a fish symbol appears on the screen. To use the fish alarm, press the menu key until the FISH ALARM menu appears on the screen. Now press the up arrow key to turn the alarm on. Repeat the above steps to turn the fish alarm off. (Note: If the Fish ID feature is off, it will be turned on when you turn the fish alarm on.) DEPTH ALARMS The depth alarms are triggered only by the bottom signal. No other echoes will activate these alarms. The depth alarms consist of a shallow and deep alarm. The shallow alarm sounds an alarm tone when the bottom goes shallower than the alarms setting. The deep alarm sounds a tone when the bottom goes deeper than its setting. Both alarms adjust the same, although through different menus. Shallow Alarm To set the shallow alarm, press the menu key repeatedly until the SHAL ALARM menu appears. Press the down arrow key to increase the shallow alarm's depth setting, the up arrow key decreases it. The number in the shallow alarms menu box shows the current shallow alarm setting. When the number reaches the desired setting, release the arrow key. When the bottom depth goes shallower than the alarms setting an alarm tone sounds. At the same time the alarm sounds, a message box appears on the screen as shown at right. Press the up arrow key to silence the alarm. This will turn the alarm sound off until the shallow alarm is triggered again. To turn the alarm off, press the menu key until the shallow alarm menu appears. Then press the up arrow key until the word OFF appears.
Deep Alarm The deep alarm adjusts the same as the shallow alarm. Use the DEEP ALARM menu to adjust the deep alarm. When the bottom signal goes deeper than the setting, an alarm tone sounds. LIGHTS The Magna III and Magna III Plus display is backlighted for night use. To turn the backlights on or off, press the menu key repeatedly until the LAMP menu appears. Now press the up arrow to turn the lights on or the down arrow to turn them off. The menu will clear automatically after a few seconds. FEET/METER The Magna III and Magna III Plus can show the depth in feet or meters. The Magna III Plus can also show temperature in degrees Fahrenheit or Celsius, speed in statute miles per hour or knots, and distance (log) in statute miles or nautical miles. When either unit is in the metric mode, all depth readings, ranges, zooms, and alarm settings are in meters. When a unit is in the feet mode, all of the above settings are in feet. To change from feet to meters or vice-versa, press the menu key until the FEET/METER menu appears. Press the down arrow key to switch to metric, the up arrow to switch to feet. Displays show in feet when the unit is first turned on. The menu will clear automatically after a few seconds or you can press the ON/CLEAR key to clear the screen.
DISPLAY CONTRAST The units display contrast is adjustable to suit different lighting conditions. This will help you see the screen from different angles, or at various times of the day. To adjust the contrast, press the menu key until the DARK/LIGHT menu appears. To

SURVEYING A LAKE The most successful anglers on any body of water are those who fish it day after day and year after year. Eventually, they learn the hot spots that produce fish consistently. They discover through experience where, and at what depth, they can expect to find the fish they want at any season. And they realize that these productive areas change throughout the year depending on water level, temperature, food, and other factors. With the Magna III, anyone can eliminate guesswork and concentrate on the areas where fish are likely to be. Even if its the first time on the lake! The most efficient way to become acquainted with a body of water is to survey it with your Magna III Start with a map of the lake, if possible, and indicate the promising spots in relation to landmarks on shore. Keep a few marker buoys in the boat, ready to toss overboard. When the Magna III indicates a school of fish, throw the buoy out. With the school thus marked, you can make your turn and come back to fish in exactly the right spot. This is essential when youre far from shore on a big lake. Unless you mark the school of fish when youre over it, you may not be able to find it again. FISH ARCHES Fish arches are created when the cone of sound passes over a fish. The distance to a fish when the cone first strikes it is shown as "A" on the next page. When the center of the cone strikes the fish, the distance is shorter as shown "B". As the cone leaves the fish, the distance increases again as shown in "C". When the Fish I.D. mode is off, the depth of the water will affect the size and shape of the fish arch due to the cone angle diameter. For example, if the cone passes over a fish in shallow water, the signal displayed on the Magna III may not arch at all. This is due to the narrow cone diameter and the resolution limitations of the display. Very small fish probably will not arch at all. Medium sized fish will show a partial arch, or a shape similar to an arch if theyre in deep water. Large fish will arch, but turn the sensitivity up in deeper water to see the arch. Because of water conditions, such as heavy surface clutter, thermoclines, etc., the sensitivity sometimes cannot be increased enough to get fish arches.

Weak bottom echo, digital readings erratic, or no fish signals: 1. Make certain transducer is pointing straight down. Clean the face of the transducer. Oil, dirt, and fuel can cause a film to form on the transducer, reducing its effectiveness. If the transducer is mounted inside the hull, be sure it is shooting through only one layer of fiberglass and that it is securely bonded to the hull. Do NOT use RTV silicone rubber adhesive or MarinetexTM. 2. Electrical noise from the boats motor can interfere with the sonar. This causes the sonar to automatically increase its Discrimination or noise rejection feature. This can cause the unit to eliminate weaker signals such as fish or even structure from the display.
3. The water may be deeper than the sonars ability to find the bottom. If the sonar cant find the bottom signal while its in the automatic mode, the digital will flash continuously. It may change the range to limits far greater than the water you are in. If this happens, place the unit in the manual mode, then change the range to a realistic one, (for example, 0-100 feet) and increase the sensitivity. As you move into shallower water, a bottom signal should appear. 4. Check the battery voltage. If the voltage drops, the units transmitter power also drops, reducing its ability to find the bottom or targets.
Bottom echo disappears at high speeds or erratic digital reading or weak bottom echo while boat is moving 1. The transducer may be in turbulent water. It must be mounted in a smooth flow of water in order for the sonar to work at all boat speeds. Air bubbles in the water disrupt the sonar signals, interfering with its ability to find the bottom or other targets. The technical term for this is Cavitation. 2. Electrical noise from the boats motor can interfere with the sonar. This causes the sonar to automatically increase its Discrimination or noise rejection feature. This can cause the unit to eliminate weaker signals such as fish or even structure from the display. Try using resistor spark plugs or routing the sonar units power and transducer cables away from other electrical wiring on the boat.
No fish arches when the Fish ID feature is off: 1. Make certain transducer is pointing straight down. This is the most common problem if a partial arch is displayed. See the Fish Arch section in your owner's manual for more information. 2. The sensitivity may not be high enough. In order for the unit to display a fish arch, it has to be able to receive the fishs echo from the time it enters the cone until it leaves. If the sensitivity is not high enough, the unit displays the fish only when it is in the center of the cone. 3. Use the Zoom feature. It is much easier to display fish arches when zoomed in on a small range of water than a large one. For example, you will have much better luck seeing fish arches with a 30 to 60 foot range than a 0 to 60 foot range. This enlarges the targets, allowing the display to show much more detail.

4. The boat must be moving at a slow trolling speed to see fish arches. If the boat is motionless, fish stay in the cone, showing on the display as straight horizontal lines. ELECTRICAL NOISE A major cause of sonar problems is electrical noise. This usually appears on the sonars display as random patterns of dots or lines. In severe cases, it can completely cover the screen with black dots, or cause the unit operate erratically, or not at all. To eliminate or minimize the effects of electrical noise, first try to determine the cause. With the boat at rest in the water, the first thing you should do is turn all electrical equipment on the boat off. Make certain the engine is off, also. Turn your Magna III on, then turn off ASP (Advanced Signal Processing). There should be a steady bottom signal on the display. Now turn on each piece of electrical equipment on the boat and view the effect on the sonars display. For example, turn on the bilge pump and view the sonar display for noise. If no noise is present, turn the pump off, then turn on the VHF radio and transmit. Keep doing this until all electrical equipment has been turned on, their effect on the sonar display noted, then turned off. If you find noise interference from an electrical instrument, trolling motor, pump, or radio, try to isolate the problem. You can usually reroute the sonar units power cable and transducer cable away from the wiring that is causing the interference. VHF radio antenna cables radiate noise when transmitting, so be certain to keep the sonars wires away from it. You may need to route the sonar units power cable directly to the battery to isolate it from other wiring on the boat. If no noise displays on the sonar unit from electrical equipment, then make certain everything except the sonar unit is turned off, then start the engine. Increase the RPM with the gearshift in neutral. If noise appears on the display, the problem could be one of three things; spark plugs, alternator, or tachometer wiring. Try using resistor spark plugs, alternator filters, or routing the sonar units power cable away from engine wiring. Again, routing the power cable directly to the battery helps eliminate noise problems. Make certain to use the in-line fuse supplied with the unit when wiring the power cable to the battery! When no noise appears on the sonar unit after all of the above tests, then the noise source is probably cavitation. Many novices or persons with limited experience make hasty sonar installations which function perfectly

INTRODUCTION Thank you for purchasing an Eagle sonar. Your MagnaView or MagnaView Plus is a high quality sonar designed for both professional and novice fishermen. These units have an automatic feature that finds and displays the bottom, fish, structure, and more! All you have to do is press the on key. However, if you wish to fine tune the unit, all you have to do is press the menu key. The Magna series has powerful features available through easy-to-use menus. To get started with your Eagle unit, first read the installation section. This is where it all begins. Improper installation can cause problems down the road. After youve read the instructions, install the unit, then read the rest of the manual. The more you know about your unit, the better it will perform for you. Take this manual for reference when you head for the water.

INSTALLATION - Bracket You can install the MagnaView on the top of a dash or from an overhead with the supplied bracket. It can also be installed in the dash with an optional IDA-3 mounting kit. If you use the supplied bracket, you may be interested in the optional GBSA-1 swivel bracket kit. This converts the MagnaView's gimbal bracket to a swivel mount which can be used on the dash or overhead mounting positions. Installation instructions for the indash and swivel mounting kits are supplied with the adapter kits. Mount the MagnaView in any convenient location, provided there is clearance when its tilted for the best viewing angle. Holes in the brackets base allow wood screw or through bolt mounting. It may be necessary to place a piece of plywood on the back side of thin panels to reinforce the panel. Make certain there is enough room behind the unit to attach the power and transducer cables. Drill a hole in the dash for the power and transducer cables. The best location for this hole is immediately under the gimbal bracket. This way, the bracket covers the hole. The smallest hole the MagnaView's power and transducer cable connectors can pass through is 3/4". However, you cant pass a power or transducer connector and another cable through a 5/8" hole. Therefore, after drilling the hole, pass the transducer connector up through the hole from under the dash. Then drop the power cable down from the front side of the dash. After installing the transducer, route its cable to the unit by passing it through the hole from under the dash. Slide the bracket over the hole, then route the transducer and power cables out the slot in the back of the bracket. Finally, fasten the bracket to the dash.

KEYBOARD BASICS The unit sounds a tone when you press any key. This tells you the unit has accepted a command. ON/CLEAR Use this key to turn the unit on. It also clears menu selections and the menus from the screen. OFF This key turns the unit off.
MENU The MagnaView and MagnaView Plus have many features that are accessed with this key. To see the first menu, press the MENU key. To see the other menus, press the MENU key repeatedly. UP and DOWN ARROWS Use these keys to adjust virtually every feature and function on the unit. NOTE: The up arrow key also stops the chart when no menus are displayed. In other words, anytime you wish to stop the chart, first make certain no menu is on the screen. Now press the up arrow key. The chart freezes and the word STOP appears at the top of the screen. To start the chart, press the up arrow key again. DISPLAY - General The lights flash for about ten seconds when the MagnaView is turned on. Three menus appear, one after the other. The menus are the lights (LAMP), feet-meter selection (FEET/METER), and contrast adjustment (DARK/LIGHT). To turn the lights on, press the up arrow key. To switch from feet to meters, press the down arrow key when the proper menu appears. To adjust the contrast, wait for the DARK/LIGHT menu to appear. Now press the up arrow key to darken the screen, the down arrow to lighten it. The menus disappear after a few seconds. If you dont want to wait, press the ON/CLEAR key to clear the menus from the screen. When the MagnaView is first turned on, the display appears similar to the one at right. The unit is in the automatic mode and the Fish
ID feature is on. The depth range displays on the upper left side of the screen. On the screen at the bottom of the previous page, the range is from 0 to 60 feet and the bottom depth is 37.3 feet. OPERATION MENUS The MagnaView and MagnaView Plus use menus to guide you through the units functions and features. The menu key accesses these features, allowing you to customize the unit to your particular needs and water conditions. All you have to do to leave one menu and enter another is press the menu key repeatedly. If you ever get lost in the menus, simply press the ON/CLEAR key. This clears the menus from the screen. Menus change depending on the mode the unit is in. For example, if the automatic mode is turned off, the sensitivity menu changes from AUTO SENS to MAN SENS. Other messages may appear in menu boxes or new menus can appear, again depending on previous selections. On the screen shown on the previous page, the lamp menu is showing. AUTOMATIC When the MagnaView is first turned on, the automatic feature is enabled. This feature automatically adjusts the units range and sensitivity according to water conditions. It always keeps the bottom depth displayed in the lower portion of the screen. To turn the automatic feature off, press the menu key until the AUTO/MAN menu appears. Now press the down arrow key. This highlights the letters MAN. The unit is now in the manual mode. Wait a few seconds and the menu will scroll off the screens left side. Pressing the ON/CLEAR key also clears it. To turn the automatic feature on again, repeat the above steps, except this time press the up arrow key. RANGE You cant adjust the range when the MagnaView is in the automatic mode. It is adjustable when the unit is in the manual mode, however. To do so, first put the unit in the manual mode. Now press the ON/CLEAR key to clear the screen. Then press the menu key until the RANGE SEL menu appears as shown below. The current range shows at the bottom of the

menu. In this case, the range is 60 feet. Now press the up arrow key to decrease the range, the down arrow key increases the range. After you select the desired range, press the ON/ CLEAR key to clear the display. If you wait a few seconds, it will automatically clear. The MagnaView and MagnaView Plus have the following ranges: 10, 20, 40, 60, 120, 240, 480, and 900 feet. and 5, 10, 20, 40, 60, 100, 200, and 300 meters. ZOOM The zoom feature enlarges all echoes on the screen. If the unit is in the automatic mode, it tracks the bottom signal, always keeping it near the bottom of the screen. This lets you see small detail, at the same time enlarging all echoes that appear on the screen. The unit doesnt track the bottom in the manual mode, and the adjustments are slightly different. Zoom - Automatic Operation To zoom the display, first press the MENU key until the RANGE/ZOOM menu appears as shown at right. Now press the down arrow key. This switches the unit into the zoom mode. A new menu immediately appears as shown below. This is the zoom size menu. Zoom size is the distance between the upper limit and the lower limit. The upper limit shows at the top left corner of the screen. The lower limit is in the bottom left corner. For example, if the upper limit is 40 feet and the lower limit is 70 feet, the zoom window size is 30 feet. The word TRACK appears in this menu when you first activate the zoom as shown at right.
This means the MagnaView is tracking the bottom in a zoom window, always keeping it on the display. Press the up arrow key to decrease the zoom size, press the down arrow key to increase the zoom size. When the unit is switched into the zoom mode, the letters ZM appear at the top of the screen. The zoom window size displays in the top right corner of the screen. On the screen shown above, the zoom size has been changed to 20 feet. To turn the zoom feature off, press the menu key until the RANGE/ZOOM menu appears. Now press the up arrow key. This switches the unit into the range mode, which turns the zoom feature off. The MagnaView and III Plus have the following zoom ranges: 10, 20, 30, 60, 120, 240, and 480 feet and 5, 10, 20, 30, 50, 100, and 150 meters. Zoom - Manual Operation To operate the zoom feature when the MagnaView is in the manual mode, first press the menu key. Then press the down arrow key in the RANGE/ ZOOM menu to place the Magna in the zoom mode. The zoom size menu automatically appears next. You can change the zoom size by pressing the up or down arrows. After you select the desired zoom size, press the menu key until the MOVE ZOOM menu appears. This menu lets you move the zoom window up or down inone foot increments by pressing the arrow keys. Thus, you can move the zoom window up towards the surface, down to the bottom, or anywhere in between. The window stays where you put it. It doesnt track the bottom signal. To turn the zoom feature off, press the menu key until the RANGE/ZOOM menu appears. Now press the up arrow key. This switches the unit into the range mode, which turns the zoom feature off.

SENSITIVITY The sensitivity menu lets you control the units ability to pick up echoes. A low sensitivity level excludes much of the bottom information, fish signals, and other detail. High sensitivity settings lets you see features, but it can also clutter the screen with noise and other unwanted signals. Typically, the best sensitivity level shows a good, solid bottom signal with grayline. The MagnaView adjusts the sensitivity level to keep a solid bottom signal on the screen. It adds a little extra when its in the automatic mode. This gives it the capability to show fish and other detail. However, situations occur where it becomes necessary to increase or decrease the sensitivity level. Typically, this occurs when you wish to see more detail, so you need to increase the sensitivity. The procedure to adjust it is the same whether the unit is in the automatic or manual mode. To change the sensitivity level, first press the menu key until the sensitivity menu appears. If the unit is in automatic, the menu shows AUTO SENS. Otherwise, the menu shows MAN SENS. Now press the up arrow key to increase the sensitivity, the down arrow to decrease it. The percentage of sensitivity in use shows in this menu. Echoes scrolling onto the screen will also show the effects of the sensitivity change. If you reach the maximum or minimum sensitivity level, a tone sounds alerting you to the limits. After youve adjusted the unit to the desired sensitivity level, press the ON/ CLEAR key to clear the display. If you wait a few seconds, it will automatically clear.
GRAYLINE Grayline lets you distinguish between strong and weak echoes. It paints gray on targets that are stronger than a preset level. This shows the difference between a hard or soft bottom, large fish versus smaller ones, or rocks and brush on the bottom. For example, a soft, muddy, or weedy bottom returns a weaker signal which shows a narrow or no gray line. A hard bottom returns a strong signal that causes a wide gray line. If you have two targets of equal size, one with gray and the other without, the target with gray is the stronger echo. This helps distinguish fish from structure, or the larger fish from a smaller one.
Grayline is adjustable. Since it shows the difference between strong and weak echoes, changing the level may require a different sensitivity setting. To change the Grayline level, first press the MENU key until the Grayline menu appears. Now press the up arrow key to increase the level, the down arrow to decrease it. The percentage of Grayline now in use shows in this menu. Echoes scrolling onto the screen will also show the effects of the Grayline change. If you reach the maximum or minimum level, a tone sounds alerting you to the limits. The level chosen by the MagnaView when its first turned on is usually adequate for most conditions. Experiment with your unit to find the Grayline setting thats best.

FISH ID The Fish ID feature identifies targets that meet certain conditions as fish. The microcomputer analyses all echoes and eliminates surface clutter, thermoclines, and other undesirable signals. In most instances, remaining targets are fish. The Fish ID feature displays symbols on the screen in place of the actual fish echoes. There are four symbol sizes: tiny, small, medium, and large. These show the relative size between targets. In other words, it displays a small fish symbol when it thinks a target is a small fish, a medium fish symbol on a larger target, etc. The microcomputer is sophisticated, but it can be fooled. It can't distinguish between fish and other suspended objects such as turtles, submerged floats, air bubbles, etc. Individual tree limbs extending outwards from a group of limbs are the hardest objects for the Fish ID feature to distinguish from fish. You may see Fish ID symbols on the screen when, in fact, there are no fish. Practice with the unit when the Fish ID feature is on and off
to become more familiar with Fish ID. When the MagnaView is first turned on, the Fish ID feature is automatically turned on, also. To turn this feature off, press the menu key until the Fish ID features menu appears as shown at right. Now press the down arrow key. This turns the feature off. To turn it back on, repeat the above steps, but press the up arrow key instead. The Fish ID feature cant be used when the MagnaView is in the manual mode. If you turn the automatic feature off, the Fish ID feature will automatically be turned off, also.
TargetTrack The MagnaView has the unique capability to "see" targets not only straight down, but also to the right and left, thanks to the BroadView transducer included with your sonar unit. This transducer has three elements: left, right, and down. The MagnaView uses all three elements to display targets between the surface and the bottom. Targets are shown as Fish ID symbols. This feature also shows the depth of the target directly above the fish symbol. In the screen shown below right, there is one symbol from the right element at 22 feet, one from the left element at 29 feet, and one from the center element at 16 feet. The TargetTrack feature identifies fish symbols coming from the right element with a "R" in front of the symbol's depth. A "L" identifies symbols from the left element. No letter identifies fish symbols from the center element. The bottom signal and the digital depth display are read from the center element only. To turn the TargetTrack feature off, simply press the MENU key until its menu appears, then press the down arrow key.

CHART SPEED The rate echoes scroll across the screen is called the chart speed. Its adjustable by pressing the menu key until the chart speed menu appears. Chart speed is set to maximum when the MagnaView is first turned on. To decrease it, press the down arrow key. Press the up arrow key to increase the speed again. The percent numbers in the Chart Speed menu box shows the speed. Echoes scrolling onto the screen will also show the effects of the change. If you reach the maximum or minimum level, an warning tone sounds. To stop the chart, first clear any menu from the screen by pressing the ON/CLEAR key. You cant stop the chart while a menu is displayed. Now press the up arrow key. The chart will freeze and the word STOP appears at the top right portion of the screen. To start the chart, press the up arrow key again.
DISPLAY MODE The MagnaView has three different screen modes. The MagnaView Plus has six. To change modes, press the MENU key until the DISP MODE (Display Mode) menu appears. Then press the up or down arrow keys until the desired mode number appears. The modes are as follows:
MAGNAVIEW ONLY CHT 1 (Chart #1) This is the default mode used when the MagnaView is first turned on. It has the following features: 1. Automatic On 2. Fish ID Feature On 3. TargetTrack Feature On 4. Digital Depth Display On
CHT 2 (Chart #2) This is the High Speed Scroll mode. It shifts the chart speed into high gear, scrolling echoes at a high rate. It has the following features: 1. Automatic Off 2. Fish ID Feature Off 3. Digital Depth Display Off
DIG 1 (Digital #1) This is the digital only screen. It shows the digital depth display at the top of the screen in very large numbers. The shallow and deep alarm settings are displayed beneath the digital depth. No chart shows on this screen.
DISPLAY MODE - MAGNAVIEW PLUS ONLY CHT 1 (Chart #1) This is the default mode used when the MagnaView Plus is first turned on. It has the following features: 1. Automatic On 2. Fish ID Feature On 3. TargetTrack On 4. Digital Depth Display On
CHT 2 (Chart #2) Same as Chart #1 plus digital surface water temperature display.
CHT 3 (Chart #3) Same as Chart #1 plus digital speed display.
CHT 4 (Chart #4) This is the High Speed Scroll mode. It has the following features: 1. Automatic Off 2. Fish ID Feature Off 3. All Digital Displays Off

DIG 1 (Digital #1) This is the first digital only screen. It shows the digital depth display at the top of the screen in very large numbers. The shallow and deep alarm settings are displayed beneath the digital depth. No chart shows on this screen.
DIG 2 (Digital #2) The digital depth display shows at the top of this screen in very large digits. The digital temperature, speed, and log shows beneath the depth. The log starts counting when the MagnaView Plus is first turned on. When the MagnaView Plus is turned off, the log is reset to zero.
ALARMS FISH ALARM The Fish Alarm sounds a tone when a fish symbol appears on the screen. To use the fish alarm, press the menu key until the FISH ALARM menu appears on the screen. Now press the up arrow key to turn the alarm on. Repeat the above steps to turn the fish alarm off. (Note: If the Fish ID feature is off, it will be turned on when you turn the fish alarm on.) DEPTH ALARMS The depth alarms are triggered only by the bottom signal. No other echoes will activate these alarms. The depth alarms consist of a shallow and deep alarm. The shallow alarm sounds an alarm tone when the bottom goes shallower than the alarms setting. The deep alarm sounds a tone when the bottom goes deeper than its setting. Both alarms adjust the same, although through different menus. Shallow Alarm To set the shallow alarm, press the menu key repeatedly until the SHAL ALARM menu appears. Press the down arrow key to increase the shallow alarm's depth setting, the up arrow key decreases it. The number in the shallow alarms menu box shows the current shallow alarm setting. When the number reaches the desired setting, release the arrow key. When the bottom depth goes shallower than the alarms setting an alarm tone sounds. At the same time the alarm sounds, a message box appears on the screen as shown at right. Press the up arrow key to silence the alarm. This will turn the alarm sound off until the shallow alarm is triggered again. To turn the alarm off, press the menu key until the shallow alarm menu appears. Then press the up arrow key until the word OFF appears.
Deep Alarm The deep alarm adjusts the same as the shallow alarm. Use the DEEP ALARM menu to adjust the deep alarm. When the bottom signal goes deeper than the setting, an alarm tone sounds. LIGHTS The MagnaView and MagnaView Plus display is backlighted for night use. To turn the backlights on or off, press the menu key repeatedly until the LAMP menu appears. Now press the up arrow to turn the lights on or the down arrow to turn them off. The menu will clear automatically after a few seconds. FEET/METER The MagnaView and MagnaView Plus can show the depth in feet or meters. The MagnaView Plus can also show temperature in degrees Fahrenheit or Celsius, speed in statute miles per hour or knots, and distance (log) in statute miles or nautical miles. When either unit is in the metric mode, all depth readings, ranges, zooms, and alarm settings are in meters. When a unit is in the feet mode, all of the above settings are in feet. To change from feet to meters or vice-versa, press the menu key until the FEET/METER menu appears. Press the down arrow key to switch to metric, the up arrow to switch to feet. Displays show in feet when the unit is first turned on. The menu will clear automatically after a few seconds or you can press the ON/CLEAR key to clear the screen.

IMPORTANT INFORMATION! If your unit is not working, or if you need technical help, please use the following troubleshooting section before contacting the factory customer service department. It may save you the trouble of returning your unit. TROUBLESHOOTING Unit wont turn on: 1. Check the power cables connection at the unit. Also check the wiring. 2. Make certain the power cable is wired properly. The red wire connects to the positive battery terminal, black to negative or ground. 3. Check the fuse. 4. Measure the battery voltage at the units power connector. It should be at least 11 volts. If it isnt, the wiring to the unit is defective, the battery terminals or wiring on the terminals are corroded, or the battery needs charging. Unit freezes, locks up, or operates erratically: 1. Electrical noise from the boats motor, trolling motor, or an accessory may be interfering with the sonar unit. Rerouting the power and transducer cables away from other electrical wiring on the boat may help. Route the sonar units power cable directly to the battery instead of through a fuse block or ignition switch 2. Inspect the transducer cable for breaks, cuts, or pinched wires. 3. Check the transducer and power connector. Make certain it's securely plugged in to the unit. Weak bottom echo, digital readings erratic, or no fish signals: 1. Make certain transducer is pointing straight down. Clean the face of the transducer. Oil, dirt, and fuel can cause a film to form on the transducer, reducing its effectiveness. If the transducer is mounted inside the hull, be sure it is shooting through only one layer of fiberglass and that it is securely bonded to the hull. Do NOT use RTV silicone rubber adhesive or MarinetexTM. 2. Electrical noise from the boats motor can interfere with the sonar. This causes the sonar to automatically increase its Discrimination or noise rejection feature. This can cause the unit to eliminate weaker signals such as fish or even structure from the display.

3. The water may be deeper than the sonars ability to find the bottom. If the sonar cant find the bottom signal while its in the automatic mode, the digital will flash continuously. It may change the range to limits far greater than the water you are in. If this happens, place the unit in the manual mode, then change the range to a realistic one, (for example, 0-100 feet) and increase the sensitivity. As you move into shallower water, a bottom signal should appear. 4. Check the battery voltage. If the voltage drops, the units transmitter power also drops, reducing its ability to find the bottom or targets. Bottom echo disappears at high speeds or erratic digital reading or weak bottom echo while boat is moving 1. The transducer may be in turbulent water. It must be mounted in a smooth flow of water in order for the sonar to work at all boat speeds. Air bubbles in the water disrupt the sonar signals, interfering with its ability to find the bottom or other targets. The technical term for this is Cavitation. 2. Electrical noise from the boats motor can interfere with the sonar. This causes the sonar to automatically increase its Discrimination or noise rejection feature. This can cause the unit to eliminate weaker signals such as fish or even structure from the display. Try using resistor spark plugs or routing the sonar units power and transducer cables away from other electrical wiring on the boat. No fish arches when the Fish ID feature is off: 1. Make certain transducer is pointing straight down. This is the most common problem if a partial arch is displayed. See the Fish Arch section in your owner's manual for more information. 2. The sensitivity may not be high enough. In order for the unit to display a fish arch, it has to be able to receive the fishs echo from the time it enters the cone until it leaves. If the sensitivity is not high enough, the unit displays the fish only when it is in the center of the cone. 3. Use the Zoom feature. It is much easier to display fish arches when zoomed in on a small range of water than a large one. For example, you will have much better luck seeing fish arches with a 30 to 60 foot range than a 0 to 60 foot range. This enlarges the targets, allowing the display to show much more detail. 4. The boat must be moving at a slow trolling speed to see fish arches. If the boat is motionless, fish stay in the cone, showing on the display as straight horizontal lines.
ELECTRICAL NOISE A major cause of sonar problems is electrical noise. This usually appears on the sonars display as random patterns of dots or lines. In severe cases, it can completely cover the screen with black dots, or cause the unit operate erratically, or not at all. To eliminate or minimize the effects of electrical noise, first try to determine the cause. With the boat at rest in the water, the first thing you should do is turn all electrical equipment on the boat off. Make certain the engine is off, also. Turn your MagnaView on, then turn off ASP (Advanced Signal Processing). There should be a steady bottom signal on the display. Now turn on each piece of electrical equipment on the boat and view the effect on the sonars display. For example, turn on the bilge pump and view the sonar display for noise. If no noise is present, turn the pump off, then turn on the VHF radio and transmit. Keep doing this until all electrical equipment has been turned on, their effect on the sonar display noted, then turned off. If you find noise interference from an electrical instrument, trolling motor, pump, or radio, try to isolate the problem. You can usually reroute the sonar units power cable and transducer cable away from the wiring that is causing the interference. VHF radio antenna cables radiate noise when transmitting, so be certain to keep the sonars wires away from it. You may need to route the sonar units power cable directly to the battery to isolate it from other wiring on the boat. If no noise displays on the sonar unit from electrical equipment, then make certain everything except the sonar unit is turned off, then start the engine. Increase the RPM with the gearshift in neutral. If noise appears on the display, the problem could be one of three things; spark plugs, alternator, or tachometer wiring. Try using resistor spark plugs, alternator filters, or routing the sonar units power cable away from engine wiring. Again, routing the power cable directly to the battery helps eliminate noise problems. Make certain to use the in-line fuse supplied with the unit when wiring the power cable to the battery! When no noise appears on the sonar unit after all of the above tests, then the noise source is probably cavitation. Many novices or persons with limited experience make hasty sonar installations which function perfectly in shallow water, or when the boat is at rest. In nearly all cases, the cause of the malfunction will be the location and/or angle of the transducer. The face of the transducer must be placed in a location that has a smooth flow of water at all boat speeds. Read your transducer owners manual for the best mounting position.

This warranty does NOT apply in the following circumstances: (1) when the product has been serviced or repaired by anyone other than us, (2) when the product has been connected, installed, combined, altered, adjusted, or handled in a manner other than according to the instructions furnished with the product, (3) when any serial number has been effaced, altered, or removed, or (4) when any defect, problem, loss, or damage has resulted from any accident, misuse, negligence, or carelessness, or from any failure to provide reasonable and necessary maintenance in accordance with the instructions of the owners manual for the product. We reserve the right to make changes or improvements in our products from time to time without incurring the obligation to install such improvements or changes on equipment or items previously manufactured. This warranty gives you specific legal rights and you may also have other rights which may vary from state to state. REMINDER: You must retain the sales slip or sales receipt proving the date of your original purchase in case warranty service is ever required.

Your unit is covered by a full one-year warranty. (See inside for complete warranty details.) If your unit fails and the failure is not covered by the original warranty, Eagle has a flat-rate repair policy that covers your unit and accessories packed with the unit at the factory. There is a 180-day warranty on all non-warranty repairs from the factory, which is similar to the original warranty, but is for 180 days rather than one year. For further details, please call us at the above number. On factory repairs, we guarantee your unit will be repaired in three working days from the time it is received. This does not include shipping time. If for some reason we cannot meet this commitment, we will extend your warranty for another full year, free of charge, from the date of repair. Eagle also gives you free UPS shipping from anywhere in the continental United States both to and from the factory for all warranty repairs. You can also use the enclosed UPS shipping label for non-warranty shipments. See inside for more information.
Remember, non-warranty repairs are subject to Eagle's published flat-rate charges and 180-day warranty. A 3 working day turnaround time at the factory repair center is guaranteed. (Does not include shipping time.)
