INSTALLATION - Bracket You can install the unit 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 IDA3 or IDA-4 mounting kit. If you use the supplied bracket, you may be interested in the optional GBSA-1 swivel bracket kit. This converts the 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 unit 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 power/transducer cable connector can pass through is 5/8". Note: Install the transducer before wiring the power cable!.After installing the transducer and power cables, 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.

GIMBAL KNOB

Attach the unit to the gimbal bracket using the supplied gimbal knobs and washers as shown above.
PERMANENT MOUNT TRANSDUCER INSTALLATION The HS-WSPC supplied with your sonar is a transom mount transducer. It can be installed on any outboard or stern-drive (inboard\outboard) powered boat. 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 instructions carefully before attempting the installation. Determine which of the mounting positions is right for your boat. Use extreme care when mounting the transducer, since 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.

Location - General

1. The transducer must be placed in a location that has a smooth flow of water at all times. If the transducer is not placed in a smooth flow of water, interference will show on the sonars display in the form of random lines or dots whenever the boat is moving. 2. The transducer should be installed with its face pointing straight down, if possible. 3. Make certain the transducer's location doesnt interfere with the trailer or hauling of the boat. Also, dont mount it closer than approximately one foot from the engines lower unit. This will prevent cavitation interference with the propeller. Typically, the transducer should be mounted as deep in the water as possible. This increases the chance that it will be in the water in high speed and reduces the possiblity of air bubble interference.

4. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps, and areators can be displayed on the sonars screen. Use caution when routing the transducer cable around these wires.
CAUTION! CLAMP THE TRANSDUCER CABLE TO TRANSOM NEAR THE TRANSDUCER. THIS WILL HELP PREVENT THE TRANSDUCER FROM ENTERING THE BOAT IF IT IS KNOCKED OFF AT HIGH SPEED.
Transducer Assembly and Mounting The best way to install this transducer is to loosely assemble all of the parts first, then place the transducers bracket against the transom and see if you can move the transducer so that its parallel with the ground. 1. Press the two small plastic ratchets into the sides of the metal bracket as shown below. Notice there are letters molded into each ratchet. Place each ratchet into the bracket with the letter A aligned with the dot stamped into the metal bracket. This position sets the transducers coarse angle adjustment for a fourteen (14) degree transom. Most outboard and stern-drive transoms have a fourteen degree angle.
2. Slide the transducer between the two ratchets. Temporally slide the bolt though the transducer assembly and hold it against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel to the ground. If it does, then the A position is correct for your hull. If the transducers face isnt parallel with the ground,

RATCHETS

remove the transducer and ratchets from the bracket. Place the ratchets into the holes in the bracket with the letter B aligned with the dot stamped in the bracket. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so its parallel with the ground. If it does, then go to step 3. If it doesnt, repeat step 2, but use a different letter until you can place the transducer on the transom correctly. 3. Once you determine the correct position for the ratchets, assemble the transducer as shown below. Don't tighten the lock nut at this time.

4. Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground. The bottom of the transducer bracket should be in line with the bottom of the hull. Don't let the bracket extend below the hull! Mark the center of the slots for the mounting holes. Drill two 5/32" holes in the marked locations for the #10 screws supplied with the transducer.

5. Remove the transducer from the bracket and re-assemble it with the cable passing through the bracket over the bolt as shown below. Attach the transducer to the transom. Slide the transducer up or down until its aligned properly on the transom as shown below. Tighten the brackets mounting screws. Adjust the transducer so that its parallel to the ground and tighten the lock nut until it touches the flat washer, then add 1/4 turn. Dont over tighten the lock nut! If you do, the transducer wont kick-up if it strikes an object in the water.
6. Route the transducer cable to the sonar unit. Make certain to leave some slack in the cable at the transducer as shown at the bottom of the previous page. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from the engines wiring, bilge pumps, VHF radio wires and cables can be picked up by the sonar. IMPORTANT! Clamp the transducer cable to the transom close to the transducer. This can prevent the transducer from entering the boat if it is knocked off at high speed. 7. Make a test run to determine the results. If the bottom is lost at high speed, or if noise appears on the display, try sliding the transducer bracket down. This puts the transducer deeper into the water, hopefully below the turbulence causing the noise. Don't allow the transducer bracket to go below the bottom of the hull!

Fish Arches

If you do not get good fish arches on your display, it could be the transducer is not parallel with the ground when the boat is at rest in the water, or at slow trolling speeds. If the arch slopes up, but not back down, then the front of the transducer is too high and needs to be lowered. If only the back half the the arch is printed, then the nose of the transducer is angled too far down and needs to be raised.

POWER CONNECTIONS -PERMANENT MOUNT UNITS ONLY
IMPORTANT! INSTALL THE TRANSDUCER BEFORE WIRING THE POWER CABLE!
The Fish ID 128 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 unit 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. IMPORTANT! Do not use this product without a 3-amp fuse wired into the power cable! Failure to use a 3-amp fuse will void your warranty! You can also attach the power cable to an accessory or power buss, however, you may have problems with electrical interference. This unit has 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.

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 Fish ID 128. Your portable sonar is now ready for use.
KEYBOARD BASICS The unit sounds a tone when you press any key. This tells you the unit has accepted a command. PWR/CLEAR Use this key to turn the unit on and off. It also clears menu selections and the menus from the screen.
Note! To turn the unit off, press and HOLD the PWR/CLEAR down. A countdown from 3 seconds appears on the screen when you hold the PWR key down for more than a couple of seconds. When the countdown reaches zero, the unit shuts off. This prevents you from accidentally turning the unit off. MENU FWD/MENU REV This sonar has many features that are accessed with these keys. To scroll forward through the menus, press the MENU FWD key repeatedly. To go backwards through the menus, press the MENU REV key repeatedly. UP and DOWN ARROWS Use these keys to adjust virtually every feature and function on the unit. The up arrow key also stops the chart when no menus are displayed. DISPLAY - General The lights flash for about ten seconds when the unit is turned on. Two menus appear, one after the other. The menus are the lights (BACK LIGHT) and feet-meter selection (FEET/METER). To turn the lights on, press the up arrow key while the backlight menu is showing. To switch from feet to meters, press the down arrow key when the proper menu appears. The menus disappear after a few seconds. If you dont want to wait, press the PWR/CLEAR key to clear the menus from the screen. When the unit is first turned on, the display appears similar to the one at right. The unit is in the automatic mode. The depth range displays on the upper left side of the screen. In the example at right, the range is from 0 to 60 feet and the bottom depth is 48.6 feet.
NOTE: Turning the unit off erases all user settings and it returns to the system defaults. For example, if you turn the lights on, then turn the unit off, the next time you turn the unit on, the lights will be off, since the default setting for the lights is off. MENUS This sonar unit uses menus to guide you through the units functions and features. The menu keys 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 a menu key repeatedly. If you ever get lost in the menus, simply press the PWR/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 backlight menu is showing. Pressing the up arrow key while this menu shows turns the back lights on.

OPERATION

AUTOMATIC When the unit 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 displayed in the lower portion of the screen. To turn the automatic feature off, press a 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 PWR/ CLEAR key also erases 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 automatic mode is on. 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 a menu key until the RANGE SEL menu appears as shown at right. 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 PWR/ CLEAR key to clear the display. If you wait a few seconds, it automatically clears. The Fish ID 128 has the following ranges: 10, 20, 40, 60, 120, 240, 480, and 900 feet. and 5, 10, 20, 40, 60, 100, 200, and 300 meters. NOTE: The depth capability of this sonar depends on the transducer installation, water and bottom conditions, and other factors. 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. Remember, however, that the unit doesnt track the bottom while in the manual mode. To zoom the display, first press a menu key until the RANGE/ZOOM menu appears. Now press the down arrow key as shown at right. This switches the unit into the zoom mode. All echoes are shown at twice their normal size. To turn the zoom off, select the RANGE/ ZOOM menu, then press the up arrow key.
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. This unit 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 a 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. 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 PWR/CLEAR key to clear the display. If you wait a few seconds, it will automatically clear.

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 three symbol sizes: 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. To turn this feature off, press a menu key until the Fish ID features menu appears as shown at right. Now press the down arrow key. To turn it on, repeat the above steps, but press the down arrow key instead. The Fish ID feature cant be used when the unit is in the manual mode. If you turn the automatic feature off, the Fish ID feature will automatically be turned off, also.
FISHTRACK This sonar automatically displays the depth of a target when the Fish ID feature places a fish symbol on the screen as shown below left. This feature is automatically enabled when the unit is turned on. To turn it off or on again, press a 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 a menu key until the chart speed menu appears. Chart speed is set to maximum when the unit is first turned on. To decrease it, press the down arrow key. Press the up arrow key to increase the speed again. The percentage of chart speed also shows on this menu. 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. CHART STOP To stop the chart, first clear any menu from the screen by pressing the PWR/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 or the PWR/CLEAR key.

DISPLAY MODE This sonar has two different screen modes Chart 1, (shown at right) which is the normal mode and Chart 2 which is the FasTrak mode. To change modes, press the MENU key until the DISP MODE (Display Mode) menu appears. Then press the up or down arrow keys to change it.
CHT 2 (Chart #2) This is the FasTrak mode. It has the following features: 1. Automatic Off 2. Fish ID Feature Off 3. Digital Depth Display Off
ALARMS FISH ALARM The Fish Alarm sounds a tone when a fish symbol appears on the screen. To use the fish alarm, press a 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 alarm off. SHALLOW ALARM The shallow alarm is triggered only by the bottom signal. No other echo will activate this alarm. The shallow alarm sounds an alarm tone when the bottom goes shallower than the alarms setting. To set the shallow alarm, press a 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 below.
Press the down 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 a menu key until the shallow alarm menu appears. Then press the up arrow key until the word OFF appears.
LIGHTS The display is backlighted for night use. To turn the backlights on or off, press a menu key repeatedly until the back light 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 This unit can show the depth in feet or meters When the 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 a menu key until the FEET/METER menu appears as shown at the bottom of the previous page. 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 PWR/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 a menu key until the DARK/LIGHT menu appears. To decrease it, press the down arrow key. Press the up arrow key to increase the contrast. The bar graph in the Dark/Light menu box shows a graph of the contrast. The screen will also show the effects of the change. If you reach the maximum or minimum level, a tone sounds alerting you to the limits. The menu will clear

automatically after a few seconds or press the PWR/CLEAR key to clear the screen.
ASP (Advanced Signal Processing) ASP is a program embedded in the computer that is specifically designed to eliminate noise. It continually monitors the signals from the receiver, determines which echoes are noise and rejects them. This allows true target echoes to display on the screen with a minimum of clutter. This feature is especially useful since it typically lets you operate the boat at all speeds without adjusting the sensitivity or other controls. When the unit is first turned on, ASP is enabled. To turn ASP off, press a menu key repeatedly until the ASP menu appears. Now press the up arrow to turn it on or the down arrow to turn it off. The menu will clear automatically after a few seconds or you can press the PWR/CLEAR key to clear the screen.
SIMULATOR A simulator is built in that can show a simulated bottom signal with fish. All features of the sonar work normally when the simulator is in use. You can change the range, zoom, and use the alarms as desired. To use the simulator, press a menu key repeatedly until the SONAR SIM menu appears. Now press the up arrow to turn it on. Repeat the above steps to turn it off, or turn the unit off and back on 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" below. 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 unit 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.
BOAT'S DIRECTION OF TRAVEL
One of the best ways to get fish arches is to expand or zoom a segment of the water. For example, from 45 to 60 feet. The smaller the segment, the better the screen resolution will be. The easiest way to do this is with the Zoom feature. This feature expands the echoes, making it easier to see detail. For the best results, turn the sensitivity up as high as possible without getting too much noise on the screen. In medium to deep water, this method should work to display fish arches. If you see fish signals when the unit is in the manual mode, but don't get fish symbols when Fish I.D. is on, try increasing the sensitivity.

WATER TEMPERATURE AND THERMOCLINES Water temperature has an important-if not controlling-influence upon the activities of all fish. Fish are cold blooded and their bodies are always the temperature of the surrounding water. During the winter, colder water slows down their metabolism. At this time, they need about a fourth as much food as they consume in the summer. Most fish dont spawn unless the water temperature is within rather narrow limits. A surface temperature meter can help you identify the desired surface water spawning temperatures for various species. Trout cant survive in streams that get too warm. Bass and other fish eventually die out when stocked in lakes that remain too cold during the summer. While some fish have a wider temperature tolerance than others, each has a certain range within which it tries to stay. Schooling fish suspended over deep water lie at the level that provides this temperature. We assume they are the most comfortable here. The temperature of water in the lake is seldom constant from top to bottom. Layers of different temperatures form, and the junction of a warm and cool layer of water is called a thermocline. The depth and thickness of the thermocline can vary with the season or time of day. In deep lakes there may be two or more at different depths. Thermoclines are important to fishermen because they are areas where fish are active. Many times bait fish will be above the thermocline while larger game fish will suspend in or just below it.

TROUBLESHOOTING 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. 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, 0-120 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 the unit 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 the transducer installation instructions in this manual for the best mounting position.

OPERATING FREQUENCY- Frequency of a sonar unit's transmitter and receiver. (See kHz.)
INTRODUCTION Welcome to the world of sportfishing sonar. Your Eagle Fish l.D. and Fish 1.0. Plus are highquality sonar designed for both professional and novice users. These units have an automatic feature that finds and displaysthe bottom depth, fish, and structure. As you becomefamiliar with your Fish 1.0., you can "fine tune" the unit to the surrounding conditionsto get the most from your sonar. (Note: All operatinginstructions forthe Fish l.D. and Fish 1.0. Plus are the same except for speed and temperature. Only the Fish l.D. Plus hasthose functions. To simplifythis manual, all references to the Fish 1.0. will also hold true for the Fish 1.0. Plus.
OUTPUTPOWER- The amplitude of electrical energytransmittedfrom the sonar unit to the transducer. Measured in watts, the higher the output power, thedeeper a sonar unit can read, and more detail can be

displayed.

PIXEL- The small dots or squareson a liquidcrystaldisplay or CAT. PIXEL DENSITY - The number of pixels per square inch on a liquid crystal display. Typically, the greater number of vertical pixels, the betterthe resolution.
PULSE LENGTh - The amount of timethat the sonartransmits. This is measured in micro-seconds. The shorter the pulse length, the better theresolution. For example, a30 micro-second pulse lengthis equal to a one inch resolution. RANGE The section of water shown on the sonar display. For example, a 60 foot range has zero for the upper limit and 60 for the lower limit. REMOTE - An intelligent "repeater" unitthat receives depth information from another sonar unit. A remote doesn't have a transmitter or receiver. However,it doeshave it's own featuresthat are adjustable and operate separatelyfrom the master. RESOLUTION - The ability of a sonar unit to separate targets from each other or from the bottom. SCALE - The markings on a sonar unit's display. To determine the depth of a target, simply compare the target'slocation 10 the locationof the scale markers on the display.

To get started with your Fish l.D., first read the installation section. This is where it all begins, and improper installation can causeproblems down the road. After you've read these instructions and installed your Fish l.D., read the rest of this manual in detail. The more you know when you get tothe water, the moreyour Fish 1.0. will dofor you. Take this manual for reference when you head for thewater. INSTALLATION Mounting
Install the unit in any convenient location, providedthere is clearance when tilted for the bestviewingangle. Holes in thebracketbase allow wood screw or through bolt mounting. Place a pieceof plywood on the back of thin panels to secure the mounting hardware. Make certain there is enough room behind the unit to attach the power and transducercables. You can routethe power and transducer cables through the one inch hole in the baseof thegimbal bracket. Then pass them through a hole in themounting surface. First passthetransducerconnectorand cable up through the hole and gimbal bracket. Then push the power cable wire down throughthe bracket and dash. After routing the cables, fill the hole with silicone rubber adhesive (RTV). Offset the bracket to coverthe majoilty of the hole.
Power Connections The Fish l.D. operatesfrom a 12 volt battery system. Attach thepower cable to an accessory or power buss. If you have problems with electrical interference, then attach the cable directly to the battery.

CONE ANGLE - Angle of the transducers cone of sound. Eagle has transducers available with coneanglesfrom 8 to 45 degrees to suit the varying needs of fishermen. CRT - Abbreviation for Cathode Hay Tube. See Video Graph. DEFINITION- The ability of a sonar unit's display to show detail. A display with high definition can show more detail than one with low

definition.

These units have reversepolarity protection. No damagewill occur if thepowerwires are reversed. (However, the unitwillnot work until the wires are attachedcorrectly.)
DISCRIMINATION - A feature available on Eagle LC.G.'s and paper graphs that separatesfalse echoesfromtruetarget information. The Discrimination feature on Eagle sonar units removes many false signals from other sonars, acoustic and electrical sources, and more. FISH ALARM- Analarm that activates when a fish or suspended object is detected. FISK ARCH A sonar with good resolution and definition can display suspended targets as upside down "Vees" or arches. These signals are typicallyfish, hence the name "Fish Arch". See page 20 for more

information.

BAIT FISH The importance of bait fish to successful fishina can't be over-emohasized. They are the principalfood of all game fish in mostwaters. Bait fish are the plankton feeding forage fish, such as minnows and shad. Bait fish can also be the young of game fish, such as crappies, bluegill, and bass. Most bali fish concentratewithin five feet of thesurface where sunlight promotesthegrowth of the plankton on which theyfeed. One method of fishing is to usethe unitto find the baitfish first. A school of baitfish will look like a "cloud" on the unit's display. Usually, game fish will be nearby,often directlybeneaththe school of baitfish.

stay. Schooling fish suspended over deep water lie at the level that provides this temperature. We assumethey are the most comfortable here.
The temperature of water in the lake is seldom constant from top to bottom. Layers of different temperatures form, and the junction of a warm and cool layer of water is called a thermocline. The depth and thickness ofthe thermocline can vary with the seasonor time of day. In deep lakes there maybe two or moreat differentdepths. Thermoclines are important to fishermen because they are areas where fish are active. Many times bait fish will be above the thermocline while larger game fish will suspend in or just below it. The Fish l.D. and l.D. Plus can detectthis invisible layer in the water, butthesensitivity will probably have to be turned up to see it.
SURVEYING A LAKE The most successful anglers on any body of water are those who fish it day afterday 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 expectto find thefishthey want at any season. And they realize that these prtductive areas change throughoutthe year depending on water level, temperature, food, and other factors.

The most efficientway to becomeacquainted with a body of water is to survey it with your unit. Start with a map of the lake, if possible, and indicate the promising spots in relation to landmarks on shore. As you go about yoursurvey, your unit will tell youthedepth and type of bottom. It will also reveal suspendedfish. Keepa fewmarkerbuoys in the boat, ready to toss overboard. When the unit indicates a school of fish, throw thebuoy 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 you're far from shore on a big lake. Unless you mark theschoolof fish when you're over it, you may not be able to find ft again.

WATERTEMPERATUREAND THERMOCLINES Water temperature has an important-if not controlling-influence upon the activities of all fish. Fish are cold blooded and their bodies are always the temperatureof the surrounding water. During the winter, colder water slows down their metabolism. At this time, they need about a fourth as muchfood as they consume in the summer.
Most fish don't spawn unless the water temperature is within rather narrow limits. The surface temperature meterbuilt into the Fish l.D. Plus helps identifythedesiredsurface waterspawning temperaturesfor various species. Trout can't survive in streams that get too warm. Bass and otherfish eventuallydie outwhen stocked in lakes that remain toocold duringthe summer.

Theunit is in the AUTO SEARCH mode when ft's first turned on. The micro-computer automatically adjuststhe sensitivity and range to find and lock onto thebottom. The digitaldepth flashes"0" until it finds and locks onto the bottom. You can leave the sensitivity in the automatic mode or manually adjust it to suit conditions.
You mayneed to increase thesensitivity to showfish symbols when the unit is in automatic. To do this, first pressthe SENS. key. The letters "SENS" will flash on the right side of the display. A verticalbar appears on the left side of the screen. ( See below.) This indicates the sensitivitylevel. To increase thesensitivity,press and holdthe up arrow key until the sensitivity is at the desired level. The down arrow key decreasessensitivity in the same manner. Notice how the sensitivity bar moves as you change settings. It will move up when the sensitivity is increased. You'll also see the change on the display. After you've finishedsetting thesensitivity level, theletters "SENS"and the sensitivity bar will disappear after eight seconds

Very small fish probablywill not arch at all. Medium sizedfish will show a partial arch, or a shape similar to an arch if they're in deep water. Largefish will arch, butturn thesensitivity up in deeperwaterto 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. One of the best ways to get fish arches is to expand or "zoom" a segment ofthe water. For example, from45 to 60 feet. The smallerthe segment, the betterthe screen resolution will be. For the best results, turn the sensitivity up as highas possible withoutgettingtoomuchnoise on the screen. In mediumto deep water, this method should work to

With highsensitivity settings,a second bottomecho (secondecho) may appear. This is normal. It'scaused by the returning signal reflecting off the surface of thewater. Then it makes a second trip to the bottom and back again.
Both 8 degree and 20 degreetransducers give accurate bottom readings, even though the bottom signal is much wider on the 20 degree model. This is because you are seeing more of the bottom. Remember, the shallowedge of the signalshowsyou the true depth. The rest of the signaltells you whether you are over rocks, mud, etc.
SIGNAL INTERPRETATION Your unit givesan accuratepicture of the bottomthat your boat is passing. A bottom of firm sand, gravel, shell, or hard clay returns a wide bottom signal. If the automaticfeature is off and the bottom signal narrows , then it means that you have moved over a mud bottom. Mud absorbs the sound wave and returns a weak signal. Turn up the sensitivity to see a better bottomsignal. Big rocks or stumps on a smooth bottom send back signals above the bottom level signal. The height of the signal depends on the target's height. As you pass over a post, it should be clearly visible as a short line extending above the bottom signal.
A steep slope returns a wide signal, the steeperthe wider.
Signals returned from a high underwater cliff are usually the widest of all.
Brush usually lies on the bottom and shows up as clumpsrising above the bottom signal. Brush signals look similarto large rocks; however Remember, when the unit's automatic feature is on, the receiver'ssensitivity automatically adjuststo thesurrounding conditions. The microcomputerplaces it at a level slightlyabovetheminimum required to pick up the bottom signal. However, ft's possible to change the sensitivity level whilethe unit is in automatic.
