Introduction

Thank you for buying an Eagle sonar! Your unit is a high-quality, remarkably-priced color 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 (MENU/PWR) key. However, if you want to fine-tune your unit, press the MENU key again. The FishEasy 320C 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, the transducer and any optional accessories, such as a speed sensor. Following recommended installation practices will pay off in optimum performance of your FishEasy 320C. 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.

Testing Determines Best Location Ideally, the shoot-thru transducer should be installed as close to the transom as possible, close to the centerline. This will give you the best performance during high speed maneuvers.
Transducer location (high speed) Transducer location (trolling speed)
Shoot-thru-hull transducer locations for high speed or trolling speed operation.
To choose the proper location for shoot-thru-hull mounting, follow these testing procedures: (You may need a helper to complete these steps.) 1. Anchor the boat in about 30 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 in the water. Adjust the sensitivity and range controls until a second bottom echo is seen on the display. (You'll need to turn off Auto Sensitivity, Auto Depth Range and ASP. Try a range setting that is two to three times the water depth. The harder (more rocky) the bottom, the easier it will be to get a second bottom signal.) Don't touch the controls once they've been set.

Manual range setting

Example of a second bottom signal. Unit is in 30 feet of water, with range set at 80 feet and sensitivity set at 87 percent.
2. Next, take the transducer out of the water and place it in the water in the sump of the boat, face down. (The transducer face is shown in the figure on the following page.) Notice how the signal strength decreases. The second bottom signal will probably disappear and the bottom signal intensity will likely decrease. 3. Now move the transducer around to find the best location with the strongest possible bottom signal. If you find a spot with an acceptable bottom signal, mark the location and move on to step 4. If you can't get an acceptable bottom signal, try turning up the sensitivity by three or five keystrokes and then move the transducer around once more. If you find a spot that works, mark it and move on to step 4. If you have to turn up sensitivity by more than five keystrokes to get a good signal, the transducer should be mounted on the outside of the hull. This is especially true if you have to turn sensitivity all the way up to get a decent bottom signal. 4. Most people can get good results by following steps 1 through 3, so this step is optional. If you want to make an extra effort to be absolutely sure that your selected location will work under all conditions, make a test run 25

Bottom of hull Speed sensor mounting configuration: side view (left) and rear view (right.)
If the base of the transom has a radius, fill the gap between the transom and the sensor with the caulking compound. This will help ensure a smooth water flow. Route the sensor's cable through or over the transom to the sonar unit. If you need to drill a hole in the transom to pass the connector through, the required hole size is 5/8". (The hole is 1" (25.4 mm) if you intend to route the sensor cable through the same hole as the transducer cable.) 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 screws. The sensor is now ready for use. Connect the sensor to the accessory socket on the back of the unit. If you have any questions concerning the installation of the sensor, please contact your local boat dealer. Power Connections The unit works from a 12-volt battery system. You can attach the power cable to your boat's accessory or power buss or directly to the battery. If you use an accessory buss but have problems with electrical interference, attach the power cable directly to the battery. If the cable is not long enough, splice #18 gauge wire onto it. CAUTION: When using the unit in a saltwater environment, we strongly recommend that you shut off the power supply to the power cable when the unit is not in use. When the unit is turned off but still connected to a power supply, electrolysis can occur in the power cable plug. This may result in corrosion of the plug body along with the electrical contacts in the cable and the unit's power socket. In saltwater environments we recommend you connect the power cable to the auxiliary power switch included in most boat designs. If that results in electrical interference, or if such a switch is not available, we recommend connecting direct to the battery and in33
stalling an inline switch. This will let you shut off power to the power cable when the unit is not in use. When you are not using the unit, you should always shut off power to the power cable, especially when the power cable is disconnected from the unit.

To unit Optional power off switch for saltwater installations
Black wire 12 volt battery Red wire with 3 amp fuse
Power and transducer connections for the FishEasy 320C sonar unit (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. 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. 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. NOTE: For more corrosion protection in saltwater or high humidity environments, apply a thin layer of electrical-grade grease to each end of the fuse before installing it in the fuse holder. 34
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, Bracket or Portable You can install the sonar unit on the top of a dash with the supplied bracket. At the time of this printing, we do not produce an in-dash mounting kit for the FishEasy 320C. If you wish to check on the future availability of this kit, refer to the accessory ordering information inside the back cover of this manual. Bracket Installation Recommended tools for this job include: drill, 1" (25.4 mm) drill bit, screwdriver. Required supplies for this job include: high quality, marine grade above- or below-waterline caulking compound, three #10 stainless steel screws. Screw length and type should be suitable for the material on which you intend to mount the bracket. Mount the unit in any convenient location, provided there is clearance when its tilted for the best viewing angle. You should also make sure there is enough room behind the unit to attach the power/transducer cable. (See the following drawings, which show the dimensions of a gimbal-mounted FishEasy 320C sonar unit.) Holes in the brackets base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back side of thin panels to reinforce the panel and secure the mounting hardware. Drill a 1" (25.4 mm) hole in the dash for the power/transducer and accessory cables. The best location for this hole is immediately under the gimbal bracket location. This way, the bracket can be installed so that it covers the hole, holds the cables in position and results in a neat installation. Some customers, however, prefer to mount the bracket to the side of the cable hole it's a matter of personal preference. 35

After drilling the hole, pass the connectors up through the hole from under the dash. If you wish, you can fill in the hole around the cable with a good marine caulking compound. (Some marine dealers stock cable hole covers to conceal the opening.)
Using the Quick Release Mounting Bracket
These units use a quick release mounting bracket. When you run the cables through the bracket's cable slots, make sure you allow enough slack for tilting the unit and attaching the connector. (The snug fit of the push-on waterproof connector requires some force to attach.) Align the bracket over the cable hole with the cable slots facing away from you and fit the cable through one of the slots. Fasten the bracket to the dash using the three screw holes. 36

Attach the unit to the bracket by first connecting the power/transducer and accessory cables. Then, hold the sonar unit vertically and slide it onto the bracket from above. (The back of the unit should be touching the front of the bracket as you lower it into position.) As you push down, the unit will lock into place with a distinct click. To adjust the viewing angle, pinch the ratchets with one hand, then tilt the unit with your other hand. Release the ratchets and the unit locks into the new position. To dismount the unit for storage, press the ratchets and lift the unit off the bracket.

Adjust viewing angle: use one hand to press and release the springloaded ratchets while you move the unit with the other hand.
Portable Sonar Installation Like many Eagle products, the FishEasy 320C sonar is capable of portable operation. It uses the optional PPP-12 portable power pack. 38
The power pack and portable transducers expand the uses for your sonar. You can use your FishEasy 320C sonar unit on your boat or take it to the dock, on a float tube, on an ice fishing trip or use it as a second sonar in a friend's boat. The PPP-12 package includes the power pack, battery adapter and a portable transducer. The transducer can be stored inside the power pack. The PPP-12 requires eight AA alkaline batteries. Batteries are not included. To use a portable power pack, you simply install the batteries and then attach the sonar unit to the power pack's bracket. Plug in the power/transducer cable and you're ready to fish. The PPP-12 has a quick-release mounting bracket built into the case. Installing the Batteries Release the latch on the front of the power pack case. Open the compartment and install eight AA batteries into the adapter. For the longest life, we recommend you use alkaline batteries. NOTE: When the unit is not in use, we recommend you unplug the power connector to reduce the possibility of corrosion or battery drain. When you store the unit, always remove the batteries because dead batteries can leak and corrode the contacts. After installing the batteries, close the case and plug the sonar unit's power cable into the socket on the power pack case.

Basic Sonar Operation

Keyboard Basics
The unit sounds a tone when you press any key. This tells you the unit has accepted a command. Numbers in the photo correspond to key explanations below:
FishEasy 320C Sonar, front view, showing screen and keyboard.
1. MENU/PWR (menu and power) This key appears in the manual text simply as MENU. Press this key to turn the unit on and off. While the unit is on, you can use this key to open the two major menus that access the many features that control 43
the unit's operation. Press MENU once to access the Sonar Menu, or twice to access the Main Menu. NOTE: You must hold the MENU key down for a countdown of five in order to turn the unit off. 2. ENT/PAGES (enter and pages) This key appears in the manual text simply as ENT. When viewing a menu or adjusting a feature, use this key to select a highlighted option. When no menus are on the screen, pressing this key will make the unit cycle through the four Sonar Chart Display Options. 3. EXIT Press this key to clear menus from the screen and return to the Sonar Chart display. You will also use EXIT to cancel alarms, and to clear any information windows that may appear on the screen. 4. UP and DOWN ARROWS These keys appear in the manual text as or. Use these keys to move through the menu options and to adjust virtually every feature and function on the sonar unit.

Memory

This unit has permanent memory that saves all user settings, even when power is removed. It does not require, nor does it use an internal backup battery, so you never have to worry about replacement batteries.
Your sonar unit will work fine right out of the box with the factory default settings. You only need to learn a few basic functions to enhance your viewing. We'll discuss them briefly here, then talk about them and all the other commands in more detail in the next section, which begins on page 58. Your unit has two primary menus that control its operation. They are the Main Menu and the Sonar Menu. 44
Main Menu The Main Menu contains some basic function commands and some setup option commands. You access the Main Menu by pressing MENU|MENU. You run a command by using or to highlight the command and then pressing ENT. To clear the Main Menu screen and return to the Page display, press EXIT. (Remember, our text style for "MENU|MENU" means "press the Menu key twice." See a full explanation of our instruction text formatting on page 9, Instructions = Menu Sequences.)
Main Menu. Main Menu Commands
There are four "basic" Main Menu commands that you'll really want to read more about. They are: Screen commands (CONTRAST, BACKLIGHT LEVEL and TRANSPARENCY): change the appearance of the display screen. Use these commands to adjust how the screen looks under various lighting conditions. Volume command: controls sound levels for key strokes and alarms. If you don't like to hear a beep each time you press a key, you can turn all sounds off by setting the volume to zero. Sound is especially useful when used with the Fish I.D. fish symbol feature and fish alarm feature. Sonar Alarms command: turns alarms on or off and changes alarm thresholds. The fish alarm, used with Fish I.D., is the most popular 45

Depth Cursor command: displays a cursor line on the sonar chart which allows you to accurately measure the depth of a sonar target. Overlay Data command: chooses what types of information (such as water temperature) to show overlaid on the sonar chart screen. Sonar Features command: launches the Sonar Features menu which controls many functions and options, including screen color mode, auto depth and sensitivity, surface clarity, noise rejection, Fish I.D. symbols, the zoom bar and zone bar. Ping Speed command: sets the rate at which sonar pings are made. Zoom Level command: controls the display size of sonar signal images.
The FishEasy 320C has three major display options. They are the Full Sonar Chart, Split Zoom Sonar Chart, and Digital Data. You access the various display modes by pressing the ENT/PAGES key. As you press this key, the unit cycles among the four page options. To return to a previous page, simply press ENT until the desired page appears again. The Full Sonar Chart is the main display option. This is a "crosssection" view of the water column beneath the boat. The chart moves across the screen, displaying sonar signal echoes that represent fish, structure and the bottom.

You can customize how the Sonar Page pictures and other data are displayed in many ways. We'll discuss all of those features and options in the Advanced Section, but to show you how easy the sonar unit is to operate, the next two pages contain a simplified, 10-step quick reference that will cover most fish finding situations. The quick reference describes how your unit will operate with all the sonar features in their automatic modes, which are set at the factory.
Basic Sonar Quick Reference
1. Mount the transducer and unit. Connect the unit to electric power and the transducer. 2. Launch your boat. 3. To turn on the unit, press and release MENU key. 4. Head for your fishing grounds. Your unit automatically displays digital depth and surface water temperature in the corner of the screen. The auto settings will track the bottom, displaying it in the lower portion of the screen. The full sonar chart will scroll from right to left, showing you what's under the boat as you cruise across the water. 5. As you're watching the sonar returns, you can change the display by: Zoom in to enlarge the chart for more detail, or Zoom out to return to full chart mode. Press MENU||ENT to select which Zoom Mode you want to use. 6. If necessary, adjust sensitivity to improve chart readability. Press MENU|ENT and the Sensitivity Menu will appear on the left of your screen. Use and to change the setting. Boosting sensitivity will show more information on your screen, which may cause clutter. Reducing sensitivity will filter out some information, but could omit important images. We recommend adjusting sensitivity until the background is lightly "peppered" that is, scattered dots appear, but individual objects (like fish arches or bottom structure) can be easily picked out of the background. 7. Watch the display for the appearance of fish arches. When you see arches, you've found fish! Stop the boat and get your lure or bait into the water at the depth indicated on the sonar chart. 51

8. Gauge the fish depth by visually comparing the fish arches with the depth scale on the right side of the screen, or get a more accurate measure with the Depth Cursor. Press MENU| to DEPTH CURSOR|ENT. Press (or ) to align the cursor line with the fish arch. The exact depth appears in a box at the right end of the cursor line. To clear the cursor, press EXIT. 9. If you are drifting at a very low speed or anchored, you are not moving fast enough for a fish to return the tell-tale fish arch signal. As you drift over a fish, or as a fish swims through the transducer's signal cone, the fish echo will appear as a straight line suspended between the surface and the bottom. 10. To turn off the unit, press and hold MENU key for three seconds.

Sonar Operations

As you can see from the quick reference on the previous page, basic operation is pretty easy, right out of the box. If you are a sonar novice, try operating the unit with the factory defaults until you get a feel for how it's working. As you're learning the basics, there is one setting you might want to tinker with from time to time 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.

These figures show results of different sensitivity levels on the same location. Fig. 1: Sensitivity at 87 percent, determined by Auto Sensitivity. Typical of full auto mode. Fig. 2: Sensitivity set at 50 percent. Fig. 3: Sensitivity set at 20 percent. Fig. 4: Sensitivity set at 100 percent.
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 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 the sonar 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 the sonar unit, manual mode allows you to set sensitivity at 100 percent (maximum) or zero percent (minimum.) Depending on water conditions, the bottom signal may completely disappear from the screen when you reduce sensitivity to about 50 percent or less! Try adjusting sensitivity in both auto and manual modes to see how they work. To adjust sensitivity: 1. Press MENU|ENT. 2. The Sensitivity Control Bar appears. Press to decrease sensitivity; press to increase sensitivity. When it's set at the desired level, press EXIT. (When you reach the maximum or minimum limit, a tone sounds.)

Display showing Sensitivity Control Bar.
NOTE: If you want to change the sensitivity in Manual Mode, first turn off Auto Sensitivity: from the Sonar Page, press MENU| to AUTO SENSITIVITY|ENT| to SENSITIVITY|ENT. Press or to pick a different sensitivity setting. When it's set at the desired level, press EXIT.

Important Tip:

While you are experimenting and learning, it's possible to scramble the settings so that the sonar picture disappears from your screen. If that happens, remember that it's easy to switch back to full automatic operation by simply restoring the factory auto settings. Here's how:
To Restore Factory Settings 1. Press MENU|MENU| to RESET OPTIONS|ENT.
2. The unit asks if you want to reset all the options. Press or to YES|ENT. All options are reset, and the unit reverts back to the original settings. Fish Symbols vs. Full Sonar Chart You may have noticed in the quick reference that we used fish arches in full sonar chart mode for our example, and not the popular Fish I.D. fish symbol feature. Here's why. 55
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 microprocessor is remarkably powerful, but it can be fooled. Some of the echoes calculated to be fish could be tree limbs or turtles! 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. 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, in one case fishermen in San Francisco Bay saw clouds of clutter in the water but no fish arches. When a down rigger was pulled up, it brought up several small jellyfish. The fishermen switched their Eagle sonar to Fish I.D., which screened out the schools of jellyfish and clearly showed the game fish there as fish symbols. Other Free Training Aids The following section discusses Fish I.D., fish alarms and other features in greater detail. If you or a friend has Internet access, you can also learn more about interpreting what you see on your sonar screen. Visit our web site, WWW.EAGLESONAR.COM. Be sure to check out the free Sonar Tutorial, which includes animated illustrations and more pictures of actual sonar returns, all described in detail. There's even a "printer friendly" version of the tutorial available on our web siteit makes a great supplement to this operation manual! For the ultimate training aid, be sure to download the free emulator software for your unit. Aside from being just plain fun, this program can help you learn both basic and advanced operations without burning boat fuel!

Advanced Sonar Options & Other Features
Material in this section is arranged in alphabetical order.
ASP (Advanced Signal Processing)
The ASP feature is a noise rejection system built into the sonar unit that constantly evaluates the effects of boat speed, water conditions and interference. This automatic feature gives you the best display possible under most conditions. The ASP feature 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 feature has four settings Off, Low, Medium and High. 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 the ASP feature off. This allows you to view all incoming echoes before they are processed by the ASP feature.
In the Sonar Features menu, Noise Rejection is selected with ASP in the default low setting.
To change the ASP level: 1. From the Sonar Page, press MENU| to SONAR FEATURES|ENT. 2. Press to NOISE REJECTION|ENT. 3. Press or to select a setting, then press ENT. 4. To return to the previous page, press EXIT|EXIT.

Alarms

This unit has two different types of sonar alarms. The first is a Fish Alarm. It sounds when the Fish I.D. feature determines that an echo is a fish. The other alarm is the Depth Alarm, which has both a Shallow and a Deep setting. Only the bottom signal will trigger this alarm. This is useful as an anchor watch, a shallow water alert or for navigation. Depth Alarms The depth alarms sound a tone when the bottom signal goes shallower than the shallow alarm's setting or deeper than the deep alarm's setting. For example, if you set the shallow alarm to 10 feet, the alarm will sound a tone if the bottom signal is less than 10 feet. It will continue to sound until the bottom goes deeper than 10 feet.
The deep alarm works just the opposite. It sounds a warning tone if the bottom depth goes deeper than the alarm's setting. Both depth alarms work only off the digital bottom depth signals. No other targets will trip these alarms. These alarms can be used at the same time or individually.
At left, Main Menu and Sonar Alarms command. At right, the Sonar Alarms menu. To adjust and turn on the shallow alarm: 1. Press MENU|MENU| to SONAR ALARMS|ENT.

Cursor line

The cursor can be moved to any location on the screen, letting you pinpoint the depth of a target. 66
1. From the Sonar Page, press MENU| to DEPTH CURSOR|ENT. 2. The depth cursor appears. Press to lower the cursor line; press to raise the cursor line. 3. To clear the depth cursor, press EXIT.

Depth Range - Automatic

When turned on for the first time, the bottom signal is automatically placed in the lower half of the screen. This is called Auto Ranging and is part of the automatic function. However, depending upon the bottom depth and the current range, you can change the range to a different depth. To do this: 1. From the Sonar Page, press MENU| to DEPTH RANGE|ENT.
The Depth Range Control Scale.
2. The Depth Range Control Scale appears. Press or to select a different depth range. A blue bar highlights the selected range. Range numbers in gray cannot be selected. 3. When the new range is selected, press EXIT to clear the menu.

Depth Range - Manual

You have complete control over the range when the unit is in the manual mode. There are 12 depth ranges, from 5 feet to 800 feet. 67
To switch to Manual Depth Range:
1. First, turn off automatic depth range. From the Sonar Page, press MENU| to AUTO DEPTH RANGE|ENT. 2. Press to DEPTH RANGE|ENT and the Depth Range Control Scale appears. 3. Press or to select a different depth range. A horizontal blue bar highlights the selected range. 4. When the new range is selected, press EXIT to clear the menu.
To turn Auto Depth Range on again: 1. From the Sonar Page, press MENU| to AUTO DEPTH RANGE|ENT|EXIT.
NOTE: The sonar's depth capability depends on the transducer installation, water and bottom conditions, and other factors.

FasTrack

This feature automatically converts all echoes to short horizontal lines on the display's far right side. The graph on the rest of the screen continues to operate normally. FasTrack gives you a rapid update of conditions directly under the boat. This makes it useful for ice fishing, or when you're fishing at anchor. When the boat is not moving, fish signals are long, drawn out lines on a normal chart display. FasTrack converts the graph to a vertical bar graph that, with practice, makes a useful addition to fishing at a stationary location.

Full Sonar Chart This is the default mode used when the unit is turned on for the first time or when it's reset to the factory defaults. The bottom signal scrolls across the screen from right to left. Depth scales on the right side of the screen aid in determining the depth of targets. The line at the top of the screen represents the surface. The bottom depth and surface temperature (if equipped with a temperature sensor or a transducer with a temp sensor built in) show at the top left corner of the screen. The FasTrack display shows just to the right of the scale. This changes all echoes into short horizontal bars, replicating a flasher sonar. The zoom bar on the far right shows the area that's zoomed when the zoom is in use. (See the Zoom section for more information.)
