Thank you for buying an Eagle sonar! Your unit is a high-quality sonar designed for both professional and novice fishermen. All Eagle sonars have an automatic mode that finds and displays the bottom, fish, underwater structure and more right out of the box. All you have to do is press the on (PWR) key. However, if you want to fine-tune your unit, press the MENU UP key. The sonar has several powerful features you can control by scrolling through easy-to-use menus with the arrow and menu keys. To get started with your Eagle sonar, first read the installation section. It contains instructions for mounting the sonar unit and the transducer. Following recommended installation practices will pay off in optimum performance of your Eagle sonar. Improper installation can cause problems down the road, especially if the transducer is badly mounted. After you've read the installation instructions, install the unit and accessories. Then, read the rest of the manual. The more you know about your sonar, the better it will work for you. Take advantage of the Simulator feature. It allows you to practice operating your sonar before you get it in the water. And when you finally head for your favorite fishing hole, take this manual along for reference.

For more information, contact the factory's Customer Service Department; phone numbers are inside the manual's back cover.
Installation Preparations
You can install the sonar system in some other order if you prefer, but we recommend this installation sequence: Caution: You should read over this entire installation section before drilling any holes in your vessel! 1. Determine the approximate location for the sonar unit, so you can plan how and where to route the cables for the transducer and power. This will help you make sure you have enough cable length for the desired configuration. 2. Determine the approximate location for the transducer and its cable route. 3. Determine the location of your battery or other power connection, along with the power cable route. 4. Install the transducer and route the transducer cable to the sonar unit. 5. Install the power cable and route it to the sonar unit. 6. Mount the sonar unit.

Attach the transducer to the transom. Slide the transducer up or down until it's aligned properly with the bottom of the hull as shown in the preceding and following figures. Tighten the bracket's mounting screws, sealing them with the caulking compound. Adjust the transducer so that it's parallel to the ground and tighten the nut until it touches the outer washer, then add 1/4 turn. Don't over tighten the lock nut! If you do, the transducer won't "kick-up" if it strikes an object in the water. 10

Bottom of hull

Deep-"vee" hull Flat-bottom hull Align transducer centerline with hull bottom and attach to transom.
6. Route the transducer cable through or over the transom to the sonar unit. Make sure to leave some slack in the cable at the transducer. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from the engine's wiring, bilge pumps, VHF radio wires and cables, and aerators can be picked up by the sonar. Use caution when routing the transducer cable around these wires. WARNING: 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. If you need to drill a hole in the transom to pass the connector through, the required hole size is 5/8". Caution: If you drill a hole in the transom for the cable, make sure it is located above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline sealant used for the mounting screws. 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! 11
TROLLING MOTOR BRACKET INSTALLATION 1. Attach the optional TMB-S bracket to the transducer as shown in the following figure, using the hardware supplied with the transducer. (Note: The internal tooth washer is supplied with the TMB-S.)
Bolt Internal tooth washer Nut TMB-S bracket

Flat washer

Attach motor mounting bracket to transducer.
2. Slide the adjustable strap supplied with the TMB-S through the slot in the transducer bracket and wrap it around the trolling motor. Position the transducer to aim straight down when the motor is in the water. Tighten the strap securely. 3. Route the transducer cable alongside the trolling motor shaft. Use plastic ties (not included) to attach the transducer cable to the trolling motor shaft. Make sure there is enough slack in the cable for the motor to turn freely. Route the cable to the sonar unit and the transducer is ready for use.

TRANSDUCER ORIENTATION AND FISH ARCHES If you do not get good fish arches on your display, it could be because
the transducer is not parallel with the ground when the boat is at rest in the water or at slow trolling speeds.

Full fish arch Proper transducer angle Transducer angles and their effects on fish arches.
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 of the arch is printed, then the nose of the transducer is angled too far down and needs to be raised. NOTE: Periodically wash the transducer's face with soap and water to remove any oil film. Oil and dirt on the face will reduce the sensitivity or may even prevent operation. 13
SHOOT-THRU-HULL PREPARATION The transducer installation inside a fiberglass hull must be in an area that does not have air bubbles in the resin or separated fiberglass layers. The sonar signal must pass through solid fiberglass. A successful transducer installation can be made on hulls with flotation materials (such as plywood, balsa wood or foam) between layers of fiberglass if the material is removed from the chosen area.
Fill with epoxy Flotation material Inner hull
Epoxy to hull first Outer hull Epoxy the transducer to a solid portion of the hull.
For example, some (but not all) manufacturers use a layer of fiberglass, then a core of balsa wood, finishing with an outer layer of fiberglass. Removing the inner layer of fiberglass and the balsa wood core exposes the outer layer of fiberglass. The transducer can then be epoxied directly to the outer layer of fiberglass. After the epoxy cures, the hull is watertight and structurally sound. Remember, the sonar signal must pass through solid fiberglass. Any air bubbles in the fiberglass or the epoxy will reduce or eliminate the sonar signals. WARNING: Do not remove any material from your inner hull unless you know the hull's composition. Careless grinding or cutting on your hull can result in damage that could sink your boat. Contact your boat dealer or manufacturer to confirm your hull specifications. To choose the proper location for thru-hull mounting, anchor the boat in 60 feet of water. Add a little water to the sump of the boat. Plug the transducer into the sonar unit, turn it on, then hold the transducer over the side of the boat. Adjust the sensitivity and range controls until a 14

Black wire 12 volt battery Red wire with 3 amp fuse
Power and transducer connections for the Cuda family sonar units (direct battery connection shown).
If possible, keep the power cable away from other boat wiring, especially the engine's wires. This will provide the best isolation from electrical noise. If the cable is not long enough, splice #18 gauge wire onto it. The power cable has two wires, red and black. Red is the positive lead, black is negative or ground. Make sure to attach the inline fuse holder to the red lead as close to the power source as possible. 17
For example, if you have to extend the power cable to the battery or power buss, attach one end of the fuse holder directly to the battery or power buss. This will protect both the unit and the power cable in the event of a short. It uses a 3-amp fuse. CAUTION: 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. 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. MOUNTING THE SONAR UNIT: In-Dash or Bracket You can install the sonar unit on the top of a dash with the supplied bracket. It can also be installed in the dash with an optional dashmounting kit (FM-5 mount kit for Cuda 168EX, FM-6 mount kit for all others covered in this manual). In-Dash Installation

For the Cuda 168EX

The following figure shows dimensions for in-dash mounting a Cuda 168EX. The in-dash adapter kit includes a template for cutting the mounting hole and complete installation directions on instruction sheet 988-0147-43. NOTE: The Cuda 168EX needs only one cable, but some of the other products covered by the FM-5 instruction sheet use more. When installing your unit, use the instructions for the transducer cable and ignore references to any others.

After installing the batteries, close the case and plug the sonar unit's power cable into the socket on the battery case.
"D" cell battery
Install batteries in power case battery adapter. PPP-13 shown.
Turn the sonar unit on. If it doesn't work, make sure the battery terminals are making good contact against the battery contacts. Also check the wiring connections on the battery adapter. The red wire on the power cable should be attached to the red wire on the battery adapter and the power cable's black wire should be connected to the black wire on the 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 sure the ones you buy are fresh. In cold weather the efficiency of dry cell batteries drops with the temperature. We find it a good idea to have the sonar unit 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. WARNING: Never heat the batteries over an open flame or direct hot air onto them. A fire or explosion could result. Portable Transducer Assembly Recommended tools for installation include a slotted screw driver and two adjustable wrenches. Assemble the transducer and bracket as shown in the following figure. Attach the transducer to the bracket with the supplied hardware. Make sure 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

Clean the chosen area of the hull before attaching the suction cup. Locate the transducer on the hull as shown in the following figure. Don't allow the bracket to extend below the hull, because 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. Your portable sonar is now ready for use.

This screen shows a typical menu, the Scroll Speed menu.
DISPLAY Opening Screen The lights flash for about 20 seconds when the unit is turned on. The backlight menu first appears on the screen. To turn the lights on, press UP ARROW. If you dont press a key, the menu will disappear after a few seconds. If you don't want to wait, press PWR to clear the menus from the screen. When the sonar unit is first turned on and the backlight menu disappears, the display screen shows the Full Chart Page, or mode. The Fish I.D. fish symbol feature is on. The depth range shows on the depth scale on the left side of the screen. In the following figure, the screen shows a depth range from 0 to 80 feet and the bottom depth is 36.9 feet, shown by the digital sonar. The water temperature is 34.5 F.

Opening screen, Full Chart page, or mode. The factory default setting has the Fish I.D. (fish symbols) turned on.
CHART SCROLL (stopping and starting) In normal operation, the sonar chart will scroll from right to left across the screen. You can stop the chart from scrolling across the screen. This is useful when you want to "freeze" the picture to study it more closely. To stop the chart, press MENU until the SCROLL SPEED menu appears. Use the DOWN ARROW to select MIN. The menu remains visible and a stationary "Stop" message appears in the screen's top right corner. To resume scrolling, use the UP ARROW to select MAX (or any speed other than minimum), then press PWR to clear the menu. For most fishing conditions you should return the chart to maximum speed. (Read more about this in the later entry on Chart Scroll Speed.) NOTE: You cannot clear the menu until you raise the chart speed again. If you accidentally press PWR to clear the menu while the chart is stopped, you must press MENU until the SCROLL SPEED menu reappears, then follow the instructions from the preceding paragraph.

If the transducer with a built-in temperature sensor is connected, a digital display for water temperature will also be shown. This 34
temperature display can be turned on and off. See the later entry on Temperature Size for off and on instructions DEPTH RANGE ZOOM (automatic and manual) When turned on, the unit automatically adjusts the range according to water conditions. When in auto mode, it always keeps the bottom displayed in the portion of the screen. You can over-ride the automatic range control and manually select a depth range. depth range lower depth
To do this, press MENU until the RANGE ZOOM menu appears. Press the DOWN ARROW to select MANUAL, then press MENU UP to display the RANGE SIZE menu. Use the arrow keys to select a desired depth range. When you're finished, press PWR to clear the menu from the display. This unit has the following depth ranges: 10, 20, 40, 80, 160, 320 and 640 feet.
Range Size menu with manual depth range set to 40 feet. This in effect "zooms" or enlarges the display to show the water column from 0 to 40 feet deep. In this figure, the boat is in 57.5 feet of water, but only the top 40 feet of the water column is shown on the screen.
ZOOM The zoom feature enlarges all images on the screen by doubling the size of the echoes (a 2X zoom). For example, if the current auto depth range is 0 to 60 feet, Zoom will show an enlarged view of the water column from 30 feet to 60 feet, always keeping the bottom in view. To zoom the display, press the MENU key until the ZOOM menu appears. Press the UP ARROW key to select ON, then press PWR to clear the menu. You can tell when the display is in Zoom mode because the top depth scale on the left of the screen will no longer show zero. For example, if the current range is 0 to 80 feet with zoom off, switching to zoom would enlarge the water column from 40 feet to 80 feet. The number 40 (instead of zero) would appear at the top of the depth range scale. To turn the zoom feature off, press the MENU key until the ZOOM menu appears. Press the DOWN ARROW key to select OFF, then press PWR to clear the menu. The top of the depth range scale returns to zero. NOTE: Using the Zoom command while in auto depth Range Zoom mode will always enlarge the echoes near the bottom, because auto Range always keeps the bottom displayed in the lower portion of the screen. When you Zoom while the unit is in manual depth Range Zoom mode, you can select one of 13 pre-set Zoom Sizes. This lets you enlarge some other particular segment of the water column. To do this, first make sure the depth Range Zoom is in manual mode. (See previous instructions for Depth Range Zoom.) Next, press the MENU key until the ZOOM menu appears. Press the UP ARROW key to select ON, then press MENU UP to display the ZOOM SIZE menu. 36

Use the arrow keys to select a desired zoom size. When you're finished, press PWR to clear the menu from the display.

Enlarged fish arches

Zoom Size menu with the 5-15 foot zoom selected. The boat is in 28 feet of water, but the screen has zoomed in on the water column from 5 to 15 feet below the surface.
You can select from these zoom size ranges: 0-10, 5-15, 10-20, 1530, 20-40, 30-60, 40-80, 60-120, 80-160, 120-140, 160-320, 240-480 and 320-640. SENSITIVITY Sensitivity controls the unit's ability to pick up echoes. If you want to see more detail, try increasing the sensitivity, a little at a time. There are situations when too much clutter appears on the screen. Decreasing the sensitivity can reduce the clutter and show the strongest fish echoes, if fish are present. As you change the sensitivity setting, you can see the difference on the chart as it scrolls. You can change the sensitivity level whether you are in Auto Sensitivity mode or Manual Sensitivity mode. The adjustment method works the same in both modes, but it gives you slightly different results. Adjusting sensitivity in Auto Sensitivity Mode is similar to manually 37
adjusting a car's speed with the accelerator pedal while cruise control is on. You can tell the car to run faster, but when you let off the gas the cruise control automatically keeps you from running slower than the minimum speed setting. In your unit, auto mode will let you increase sensitivity to 100 percent, but the unit will limit your minimum setting. This prevents you from turning sensitivity down too low to allow automatic bottom tracking. When you change the setting with auto turned on, the unit will continue to track the bottom and make minor adjustments to the sensitivity level, with a bias toward the setting you selected. Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a car without cruise control you have complete manual control of the car's speed. In your unit, manual mode allows you to set sensitivity at 100 percent (maximum) or zero percent (minimum.) Depending on water and bottom conditions, the bottom signal may completely disappear from the screen when you reduce sensitivity to about 45 percent or less! Try adjusting sensitivity in both auto and manual modes to see how they work.

Fish I.D. is an easier way for a sonar novice to recognize a fishy signal return when he sees it. However, locating fish by symbol only has some limitations. Your sonar unit's microcomputer is sophisticated, but it can be fooled. It can't distinguish between fish and other suspended objects such as trotlines, turtles, submerged floats, air bubbles, etc. Individual tree limbs extending outward from a group of limbs are the hardest objects for the Fish I.D. feature to distinguish from fish. To see what's under your boat in maximum detail, we recommend you turn off Fish I.D. and begin learning to interpret fish arches. You may see Fish I.D. symbols on the screen when actually, there are no fish. The reverse is also true Fish I.D. can actually miss fish that are present. Does that mean Fish I.D. is broken? No the feature is simply interpreting sonar returns in a specific way to help take some of the work out of reading the screen. Remember: Fish I.D. is one of the many tools we provide so you can analyze your sonar returns for maximum fish finding information. This and other features can help you successfully "see" beneath the boat under varied water and fishing conditions. So, practice with the unit in both the Fish I.D. mode and without to become more familiar with the feature. This unit's default Fish I.D. setting is on. 42
Fish I.D. is most handy when you're in another part of the boat or performing some task that prevents you from watching the sonar screen. Then, you can turn on Fish I.D. and the audible FISH ALARM. When that lunker swims under your boat, you'll hear it! Fish I.D. can also be useful when you want to screen out some of the sonar detail gathered by your unit. For example, it can help cut through the clutter of suspended bubbles caused by wave action or boat wakes. To turn Fish I.D. off, press MENU until the FISH ID menu appears. Press DOWN ARROW to select OFF, then press PWR. To turn it back on, repeat the above steps, but press UP ARROW to select ON. FISHTRACK The FishTrack feature shows the depth of a fish symbol when it appears on the display. To turn it on, press MENU until the FISH ID menu appears. Press UP ARROW to select TRACK ON, then press PWR. To turn it off, repeat the above steps, but press DOWN ARROW to select OFF. (If you want to turn off FishTrack depths but leave Fish I.D. on, press DOWN ARROW to select ON, then press PWR.) Remember, Fish I.D. must be on in order to use the FishTrack feature.

CHART SCROLL SPEED The rate that echoes scroll across the screen is called the chart scroll speed. The default for this unit is "max" (100 percent); we recommend that you leave the scroll speed set there for virtually all fishing conditions. However, you might consider experimenting with chart speed when you are stationary or drifting very slowly. You may sometimes achieve better images as you slow down the chart speed to match how fast you are moving across the bottom. If you are at anchor, ice fishing or fishing from a dock, experiment with a chart speed of 20 percent. If you are drifting slowly, try a chart speed of 50 percent. When you are stationary and a fish swims through the sonar signal cone, the image appears on the screen as a long line instead of a fish arch. Reducing the chart speed may result in a shorter line that more closely resembles a regular fish return. Adjust scroll speed by pressing MENU until SCROLL SPEED appears. Press UP ARROW to increase it and press DOWN ARROW to decrease it. Press PWR to clear the menu. To return to the original setting, repeat the above steps, but use the arrow keys to set the speed at MAX before clearing the menu. NOISE REJECT and ASP (Advanced Signal Processing) The ASP (Advanced Signal Processing) feature is a noise rejection system built into the sonar unit. It constantly evaluates the effects of boat speed, water conditions and electrical interference and automatically gives you the best display possible under most conditions. ASP is an effective tool in combating noise. In sonar terms, noise is any undesired signal. It is caused by electrical and mechanical sources such as bilge pumps, engine ignition systems and wiring, air bubbles passing
over the face of the transducer, even vibration from the engine. In all cases, noise can produce unwanted marks on the display. The ASP noise rejection feature is especially useful because it typically lets you operate the boat at all speeds without adjusting the sensitivity or other controls. The ASP feature has three settings Off, Low and High. When first turned on, noise rejection is set on low. If you have high noise levels, try using the high ASP setting. However, if you are having trouble with noise, we suggest that you take steps to find the interference source and fix it, rather than continually using the unit with the high ASP setting. There are times when you may want to turn ASP off. This allows you to view all incoming echoes before they are processed by the ASP feature. To change the ASP setting, press MENU DOWN until NOISE REJECT appears. Use the up and down arrow keys to select the desired setting, then press PWR to clear the menu.

Weak bottom echo, digital readings erratic, or no fish signals: 1. Make certain the 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 Marine-Tex epoxy. 2. Electrical noise from the boat's 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 sonar's ability to find the bottom. If the sonar can't find the bottom signal while it's in the automatic mode, the digital sonar display 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 unit's 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 boat's 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 51
spark plugs or routing the sonar unit's power and transducer cables away from other electrical wiring on the boat. No fish arches when the Fish I.D. feature is off: 1. Make certain the transducer is pointing straight down. This is the most common problem if a partial arch is displayed. 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 fish's echo from the time it enters the cone until it leaves. If the sensitivity is not high enough, the unit shows 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 screen as straight horizontal lines. NOISE A major cause of sonar problems is electrical noise. This usually appears on the sonar's 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 sure the engine is also off. Turn your sonar on, then turn off Noise Reject [also known as the ASP feature (Advanced Signal Processing)]. Sensitivity should be set at 90-95 percent. 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 sonar's display. For 52
