Align plastic ratchets in bracket.
B. Two-piece bracket: Locate the four plastic ratchets in the transducer's hardware package. Press two ratchets into the sides of the plastic bracket and two on either side of the transducer as shown in the following illustrations. Notice there are letters molded into each ratchet. Place the ratchets into the bracket with the letter "A" aligned with the alignment mark molded into the bracket. Place the ratchets onto the transducer with the letter "A" aligned with the 12 o'clock position on the transducer stem. These positions set the transducer's coarse angle adjustment for a 14 transom. Most outboard and stern-drive transoms have a 14 angle.

2. Aligning the transducer on the transom. A. One-piece bracket: Slide the transducer between the two ratchets. Temporarily 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 transducer's face isn't parallel with the ground, 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 it's parallel with the ground. If you can, then go to step 3A. If it doesn't, repeat step 2A, but use a different alignment letter until you can place the transducer on the transom correctly.

B. Two-piece bracket: Assemble the transducer and bracket as shown in the following figure. Temporarily slide the bolt though the transducer assembly but don't tighten the nut at this time. Hold the assembled transducer and bracket 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" positions are correct for your hull. If the transducer's face isn't parallel with the ground, remove and disassemble the transducer and ratchets. Place the ratchets into the 13
bracket holes with the letter "B" aligned with the bracket alignment mark. Place them on the transducer aligned with the 12 o'clock position on the transducer stem. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so it's parallel with the ground. If you can, then go to step 3B. If it doesn't, repeat step 2B, but use a different alignment letter until you can place the transducer on the transom correctly.

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". 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 your 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. For the best results, attach the power cable directly to the battery. You can attach the power cable to an accessory or power buss, however you may have problems with electrical interference. Therefore, it's safer to go ahead and attach the power cable directly to the battery. CAUTION: When using the unit in a saltwater environment, we strongly recommend that you shut off the power supply to the power cable when 24
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 installing 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. 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 in-line 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. 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. An optional 8-foot, CA-4 external power cable with a cigarette lighter adapter is available from Eagle.

Mounting the Unit: Bracket, In-Dash or Portable
You can install the sonar unit on the top of a dash with the supplied gimbal bracket. It can also be installed in the dash or mounted on a portable power supply. If you use the supplied bracket, you may be interested in the optional R-A-M bracket mounting system. This converts the unit's gimbal bracket to a swivel mount, which can be used on the dash or overhead mounting positions. Installation instructions are supplied with the R-A-M mounting kits. Bracket Installation Mount the unit in any convenient location, provided there is clearance behind the unit when it's tilted for the best viewing angle. You should 26
also make sure there is enough room behind the unit to attach the power and transducer cables. (A drawing on the next page shows the dimensions of a gimbal-mounted sonar unit.) Holes in the bracket's base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back side of thin fiberglass panels to reinforce the panel and secure the mounting hardware.
Front Install the gimbal bracket. Orient the bracket so the arms slope toward the front of your unit.
Drill a 1-inch (25.4 mm) hole in the dash for the power and transducer 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. After drilling the hole, pass the transducer connector up through the hole from under the dash. Pass the power cable's bare-wire end down though the hole from the top. If you wish, you can fill in the hole around the cables with a good marine caulking compound. (Some marine dealers stock cable hole covers to conceal the opening.) No matter what type of installation you prefer, be sure to leave enough slack in the cables to allow tilting or swiveling 27

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 45. Your unit has three primary menus that control its operation. They are the Main Menu, the Sonar Menu and the Pages Menu. 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 the 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 4, 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 command: changes the contrast or brightness of the display screen. Use this command to adjust how the screen looks under various lighting conditions. Sounds command: enables or disables the sounds for key strokes and alarms, controls the volume and sets the alarm style. If you don't like to hear a beep each time you press a key, you can turn this off, or select tunes or sound effects instead. The sounds are 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 use. It tells you when the sonar sees a fish. You can also set deep or shallow depth alarms and zone alarms. Popup Help command: turns the pop-up help boxes on or off. When you select a menu command, these information boxes appear to tell you what the command does or how to use the command. The default setting is on, which is really handy while you're learning. The remaining Main Menu commands are for more advanced functions, mostly setting various sonar options. (They're all detailed in Sec. 4.) Units of Measure command: selects the units of measure used for showing speed/distance, depth and temperature. Set Keel Offset command: calibrates the unit to show depth under the keel or actual depth from the surface. Calibrate Water Speed command: adjusts how a speed sensor measures water speed. Reset Water Distance command: resets water distance log to zero. Sonar Simulator command: turns the simulator feature on and off. Useful for learning how to operate the unit and all its functions. 34

Reset Options command: returns all options and auto functions to their original factory settings. It's a great safety net while you're learning and experimenting with various settings. Set Language command: your unit has menus in 10 different languages. This command switches from one language to another. Software Information command: tells you which version of the operating software is loaded in your unit. Sonar Menu The Sonar Menu contains commands for the major sonar features and options. You access the Sonar Menu by pressing the MENU key one time. You run a command by using the or to highlight the command and then pressing ENT. To clear the menu screen and return to the Page display, press EXIT.
Sonar Page Menu. Most of these functions are discussed in Sec. 4. Sonar Menu Commands
The Sonar Menu contains commands for the major sonar features and options. Most of them are only described in detail in Sec. 4, but Sensitiv35
ity and Auto Sensitivity are important basic functions that are discussed both here and in Sec. 4. The other Sonar Menu commands include: Grayline command: separates fish and structure near the bottom from the actual bottom, and defines bottom composition/hardness. Depth Range command: manually sets the depth range shown on the sonar chart. Auto Depth Range command: automatically sets the depth range shown on the sonar chart to always keep the bottom in view. Stop Chart command: stops the sonar chart from scrolling. Used when you want to "freeze" the image for closer study. Chart Speed command: sets the scrolling speed of the sonar chart. 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 frequency selection, 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.
The Pages Menu controls the four major display options. They are the Full Sonar Chart, Split Zoom Sonar Chart, Split Frequency Sonar Chart and Digital Data. You access the Pages Menu by pressing the PAGES key. You select a display option by using or to highlight the option and then pressing ENT. (You can clear the Pages Menu by pressing EXIT.) 36

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 Section 4, but to show you how easy the sonar unit is to operate, see the following 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. 38
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 PWR 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: press ZIN. Zoom out to return to full chart mode: press ZOUT. 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. 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. 39

Try adjusting sensitivity in both auto and manual modes to see how they work. 41
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.)
At left, Sonar Menu with Sensitivity command selected. At right, the 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 to YES|ENT. All options are reset, and the unit reverts back to the original settings. 42
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. 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 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 sonar options 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! 43

4. To set the lower boundary for the Zone Alarm, use or to select
depth. 5. Press EXIT| to ZONE ALARM ENABLED|ENT|EXIT. Now, any echo fish, bottom, structure within the zone alarm's depth range will trigger the zone alarm. 6. To turn off the alarm, press ALARM| to ZONE ALARM ENABLED|ENT|EXIT.
To switch to a different depth setting, open the Sonar Alarms menu and repeat the instructions in steps 3 and 4 above. Fish Alarm Use the fish alarm for a distinctive audible alarm when fish or other suspended objects are detected by the Fish I.D. feature (Fish I.D. must be turned on for the Fish Alarm to work). A different tone sounds for each fish symbol size shown on the display.
To turn the fish alarm on: 1. Press ALARM.
2. Press to FISH ALARM|ENT|EXIT. 3. To turn off the alarm, press ALARM| to FISH ALARM|ENT|EXIT.

Brightness

See the entry in this section for Screen Contrast and Brightness.

Calibrate Speed

The speed sensor can be calibrated to compensate for inaccuracies. Before you change the setting, first calculate the percentage that the speed is off. You will enter this percentage in a moment. For example, if you figure the sensor is reading 10 percent faster than actual speed, you will enter 10 in the calibration window. If the sensor is reading 5 percent slower than true speed, you will enter + 5 in the window. Perform your test in relatively calm water free of current, if possible. (Unless, of course, you are taking the current speed into consideration when making your calculation.) After you have a correction figure, here's how to enter it: 1. Press MENU|MENU| to CALIBRATE WATER SPEED|ENT. 2. Enter the number you calculated earlier: press or to change the first character (+ or ), then press to move the cursor to the next number and repeat until the percentage is correct, then press EXIT.

Chart Speed

The rate that echoes scroll across the screen is called the chart speed. The default is maximum; we recommend that you leave the 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 around 50 percent. If you are drifting slowly, try a chart speed around 75 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. 49

Ping Speed & HyperScroll
Ping Speed controls the rate at which the transmitter and transducer broadcast sonar sound waves pings into the water. The unit has a default ping speed of 50 percent. At normal boating speeds, this automatically provides enough return echoes to refresh the screen and scroll the chart at maximum chart speed. However, when you are running at high speeds, or just want the fastest possible screen update, you may want to use the HyperScroll feature. When you change the Ping Speed to any setting greater than 50 percent, the unit automatically enters HyperScroll mode. 62
These faster ping rates allow you to maintain a high-detail picture on the screen, and the screen refresh rate and chart scroll speed can keep pace with the boat as it moves quickly over the bottom terrain. When using HyperScroll, you may also need to manually decrease the sensitivity for optimum performance. Depending on water depth and other conditions, HyperScroll may cause a second bottom echo to return to the transducer during the next ping cycle, or sounding. This can result in a large amount of clutter appearing on the screen. If this occurs, just decrease the sensitivity to a level that eliminates the clutter. When you turn HyperScroll off, you can return to your original sensitivity level. To change Ping Speed: 1. From the Sonar Page, press MENU| to PING SPEED|ENT. 2. The Ping Speed Control Bar appears. Press to increase ping speed; press to decrease ping speed. When it's set at the desired level, press EXIT. To adjust Sensitivity: 1. From the Sonar Page, 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.) To turn off HyperScroll: 1. From the Sonar Page, press MENU| to PING SPEED|ENT. 2. The Ping Speed Control Bar appears. Press to decrease ping speed to 50 percent. When it's set at the desired level, press EXIT. When you boost ping speed and switch into HyperScroll, the width of the FasTrack bar graph display doubles in width at the right side of the screen. The allows you to better see the virtually instantaneous sonar returns, just as you would on a flasher sonar unit. For more information on FasTrack, see it's entry in this section.

Pop-up Help

Help is available for virtually all of the menu labels on this unit. By highlighting a menu item and leaving it highlighted for a few seconds, a "pop-up" message appears that describes the function of the menu item. This feature is on by default. To set up Popup Help: Press MENU|MENU| to POPUP HELP. With the option highlighted, press ENT to check it (turn on) and uncheck it (turn off.) After the option is set, press EXIT to return to the page display.

4. Press to the second number, them press to change the number to 5, then press EXIT. The depth indicators now accurately show the water depth from surface to bottom.

Set Language

This unit's menus are available in 10 languages: English, French, German, Spanish, Italian, Danish, Swedish, Russian, Dutch and Finnish. To select a different language: 1. Press MENU|MENU| to SET LANGUAGE|ENT. 2. Use or to select a different language and press ENT. All menus now appear in the language you selected.
Software Version Information
From time to time, Eagle updates the operating system software in some of its products. These software upgrades are usually offered to customers as free downloads from our web site, www.eaglesonar.com. These upgrades make the unit perform better or introduce a new feature or function. You can find out what software version is running in your sonar unit by using the Software Information command.

1. Press MENU|MENU| to SOFTWARE INFO|ENT. 2. Read the information displayed on the screen. 3. To return to the last page displayed, press EXIT|EXIT.

Sonar Color Mode

The default color scheme for the sonar chart is grayscale, but we offer other variations to suit your viewing preferences. You can select the chart to be displayed in reverse grayscale, bottom black or FishReveal mode. (For more information on FishReveal, see the entry on that topic elsewhere in this section.) To change the chart mode color scheme: 1. From the Sonar Page, press MENU| to SONAR FEATURES|ENT. 2. Press to SONAR COLOR MODE|ENT. 3. Press or to Mode Name|ENT. 4. Press EXIT|EXIT to return to the Sonar Page.
Sonar Chart Display Options
The Pages Menu offers four chart display options for dual-frequency models and three options for single-frequency models. To access them, press PAGES| to Option Name|EXIT.
Pages Menu showing sonar chart display options (at left, dual-frequency menu; at right, single-frequency menu).
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 70
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.)

Sonar Simulator

This unit has a built-in simulator that lets you run it as if you were on the water. All sonar features and functions are useable. When in simulator mode, you will see [Simulator Mode] in the Sonar Page title bar. To use the simulator: 1. From the Sonar Page, press MENU|MENU| to SONAR SIMULATOR|ENT. 2. Turn off Sonar Simulator by pressing MENU|MENU| to SONAR SIMULATOR|ENT|EXIT. NOTE: If you turn on your unit before attaching a transducer, it may enter a demo mode. The words "demo mode" flash on the bottom of the screen and a sonar chart plays much like the simulator. Unlike the simulator, the demo mode is for demonstration only, and will automatically stop as soon as you turn on the unit with a transducer attached. The simulator will continue to function normally.

Stop Chart

If you are running multiple units on a boat, there are times when you may want to turn off the sonar. This command turns off the sonar and stops the chart from scrolling. Sonar restarts automatically each time you turn on your unit. 1. Press MENU| to STOP CHART|ENT|EXIT. To turn on sonar and start the chart scrolling again, repeat the above step. 74

Surface Clarity

The markings extending downward from the zero line on the chart are called "surface clutter." These markings are caused by wave action, boat wakes, temperature inversion and more. The surface clarity control reduces or eliminates surface clutter signals from the display. It does this by changing the sensitivity of the receiver, decreasing it near the surface and gradually increasing it as the depth increases. There are three levels of surface clarity available: low, medium, or high. It can also be turned off. The default level is off. To adjust the Surface Clarity level: 1. From the Sonar Page, press MENU| to SONAR FEATURES|ENT.
