Notes iv
Section 1: Read Me First! How this manual can get you out on the water, fast! Welcome to the exciting world of digital sonar! We know you're anxious to begin finding fish, but we have a favor to ask. Before you grab your unit and begin installing it, please give us a moment or two to explain how our manual can help you get the best performance from your compact, wide-screen, fish finder. First, we want to thank you for buying anEagle sonar.
After you've gained some experience with your sonar, you'll want to check out Section 4, which discusses more advanced Sonar Options and Other Features. When you come to a sonar menu command on the unit's screen, you can look it up in the manual by skimming over the table of contents, just flipping through Section 3 or scanning through the sonar options in Section 4. If you're having difficulty with your sonar, you can find an answer to the most common problems in Section 5, Sonar Troubleshooting.
Back-up memory: .......... Built-in memory stores sonar records for decades. Languages:...................... 10; menu languages selectable by user. Sonar Frequency:...................... 50/200 kHz for SeaFinder 480DF; 200 kHz for FishMark 480. Transducers: .................. A dual-frequency Skimmer transducer with built-in temperature sensor is packed with the SeaFinder 480DF. It has 35°/12° cone angles.
Speed/distance log: ....... Optional (requires optional speed sensor). NOTICE! The storage temperature range for your unit is from -4 degrees to +167 degrees Fahrenheit (-20 degrees to +75 degrees Celsius). Extended storage in temperatures higher or lower than specified will damage the liquid crystal display in your unit. This type of damage is not covered by the warranty. For more information, contact the factory's Customer Service Department; phone numbers are listed on the last page.
menu command to use by finding the boldface command text. The following paragraphs explain how to interpret the text formatting for those commands and other instructions: Arrow Keys The arrow keys control a horizontal line depth cursor on the sonar screen. The arrow keys also help you move around the menus so you can execute different commands. They are represented by symbols like these, which denote the down arrow key, the up arrow, the left arrow and the right arrow: ↓ ↑ ← →.
Translated into complete English, step 1 above would mean: "Start on the Sonar Page. Press the Menu key then repeatedly press (or press and hold) the down arrow key to scroll down the menu and select (highlight) the Sonar Features menu command. Then press the Enter key." Step 2 would mean: "Press the right arrow key (for dual-frequency units) or press the right arrow key followed by the down arrow key (for single-frequency units) to select (highlight) the Fish ID symbols command.
Section 2: Installation & Accessories 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.
These are all "kick-up" mounting brackets. They help prevent damage if the transducer strikes an object while the boat is moving. If the transducer does "kick-up," the bracket can easily be pushed back into place without tools. Read these instructions carefully before attempting the installation. Determine which of the mounting positions is right for your boat. Use extreme care if mounting the transducer inside the hull, because once it is epoxied into position, the transducer usually cannot be removed.
then the chosen location must be in the water at all times. If the transducer is not placed in a smooth flow of water, interference caused by bubbles and turbulence will show on the sonar's display in the form of random lines or dots whenever the boat is moving. NOTE: Some aluminum boats with strakes or ribs on the outside of the hull create large amounts of turbulence at high speed. These boats typically have large outboard motors capable of propelling the boat at speeds faster than 35 mph.
How low should you go? For most situations, you should install your Skimmer transducer so that its centerline is level with the bottom of the boat hull. This will usually give you the best combination of smooth water flow and protection from bangs and bumps. Transom Transducer centerline Hull bottom Align transducer centerline with hull bottom. However, there are times when you may need to adjust the transducer slightly higher or lower.
However, the shoot-thru-hull installation does have its drawbacks. First, some loss of sensitivity does occur, even on the best hulls. This varies from hull to hull, even from different installations on the same hull. This is caused by differences in hull lay-up and construction. Second, the transducer angle cannot be adjusted for the best fish arches. This can be a problem on some hulls that sit with the bow high when at rest or at slow trolling speeds.
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.
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.
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.
B. Two-piece bracket: Once you determine the correct position for the ratchets, assemble the transducer as shown in the figure in step 2B. Don't tighten the lock nut at this time. 4. Drilling mounting holes. Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground. The transducer's centerline should be in line with the bottom of the hull. Don't let the bracket extend below the hull! Mark the center of each slot for the mounting screw pilot holes.
Both bracket types: 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.
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.
Transducer mounted on trolling motor, side view. 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. Partial fish arches Transducer aimed too far forward Transducer aimed too far back 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.
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.
100 grit sandpaper. The surface of the hull must be flat so the entire transducer face is in contact with the hull prior to bonding. Spread epoxy here Sand this surface Epoxy transducer to hull. 2. Follow the instructions on the epoxy package and mix it thoroughly. Do not mix it too fast, because it will cause bubbles to form in the epoxy. Apply a small amount on the face of the transducer as shown above, then spread a small amount onto the sanded area on the hull.
If a second temp sensor is used, it must be the model TS-2U. This model has a fixed electronic "address" which designates it as the second of two temp sensors. Dual temperatures are only displayed on the Full Chart page. The Large Digital page will only display the primary temperature sensor. See the following wiring diagram for temperature and speed sensor combinations. Sonar unit rear view T2-U temp sensor Power/transducer cable Temp sensor built into transducer.
Optional Speed Sensor Installation All the units in this series can display speed and distance traveled, but only the SeaFinder 480DF comes packed with a speed sensor. If you wish to purchase an optional additional sensor for your unit, refer to the accessory ordering information inside the back cover of this manual. The following instructions describe how to install the speed sensor. Recommended tools for this job include: drill, 5/8" drill bit, 1/8" drill bit for pilot holes, screwdriver.
Good location Stern view showing good location for mounting sensor on transom. 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. Transom Bottom of hull Bottom of hull Speed sensor mounting configuration: side view (left) and rear view (right.) Route the sensor's cable through or over the transom to the sonar unit.
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 the unit is not in use.
Optional power off switch for saltwater installations To unit Black wire 12 volt battery Red wire with 3 amp fuse Power connections for the sonar unit. 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.
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.
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 the unit.
place against the side of the hole. Finally, fasten the bracket to the dash. Attach the unit to the gimbal bracket using the supplied gimbal knobs and washers. In-Dash Installation You can mount the unit in the dash with an optional FM-5 In-Dash Adapter Kit. The kit includes mounting hardware, a template for cutting the hole and an instruction sheet, part 988-0147-43. 146.5 [5.76] Top R 7.9 [0.31] In-Dash Template 113.5 [4.

For setup directions, refer to the pack's instruction sheet, part 988-0147-601. "D" cell battery Install batteries in power pack battery adapter. Face Cover Your unit comes with a white protective cover that snaps on and off the front of the unit. This cover is intended for use when your unit and the vehicle it's mounted in are idle.
Section 3: Basic Sonar Operation This section addresses the unit's most basic sonar operations. The instructions presented here in Sec. 3 follow a chronological order. Sec. 4, Sonar Options & Other Features, will discuss options and other more advanced functions and utilities. The material in Sec. 4 is arranged in alphabetical order. Before you turn on the unit, it's a good idea to learn about the different keys, the Main Menu, the Sonar Menu, the four Page options and how they all work together.
1. PWR/LIGHT (Power & Light) – The PWR key turns the unit on and off and activates the backlight. 2. PAGES – Pressing this and the ↑ ↓ arrow keys switches the unit between the four different page options. (Full Sonar Chart, Split Zoom Sonar Chart, Split Frequency Sonar Chart and Digital Data.) 3. MENU – Press this key to show the menus and submenus, which allow you to select a command or adjust a feature. 4.
Menus 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 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.
• 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.
Sensitivity 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.
Pages Menu showing some Sonar display options (at left, dual-frequency menu; at right, single-frequency menu). 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. Digital data overlay (depth & temperature) Surface signal Surface clutter Depth scale In FasTrack, fish arches show as horizontal bars.
Sonar chart display options (from left) split zoom (all models) and split frequency (SeaFinder 320DF only). Digital data sonar chart display option. 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.
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.
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 PWR key for three seconds. Sonar Operations As you can see from the quick reference, basic operation is pretty easy, right out of the box.
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! Fig. 1 Fig. 2 Fig. 3 Fig.
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.
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.
"printer friendly" version of the tutorial available on our web site…it 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! Eagle is one of the first sonar manufacturers to provide this type of training tool for customers. This PC application simulates the actual sonar unit on your computer.
Section 4: 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.
To change the ASP level: 1. From the Sonar Page, press MENU|↓ to SONAR FEATURES|ENT. 2. Press → ↓ or ↓ 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 three different types of sonar alarms. The first is the Fish Alarm. It sounds when the Fish I.D. feature determines that an echo is a fish. Another alarm is the Zone Alarm, which consists of a bar on the side of the screen.
To adjust and turn on the shallow alarm: 1. Press ALARM. 2. Press → to SHALLOW ALARM DEPTH|ENT. 3. Press ↑ or ↓ to change the first number, then press → to move the cursor to the next number and repeat until the depth is correct, then press ENT. 4. Press ← to SHALLOW ALARM ENABLED|ENT|EXIT. 5. To turn off the alarm, press ALARM|ENT|EXIT. To switch to a different depth setting, open the Sonar Alarms menu and repeat the instructions in step 3 above. To adjust and turn on the deep alarm: 1. Press ALARM. 2.
Adjust Zone Alarm selection box, with Upper selected. 3. To set the upper boundary for the Zone Alarm, use ← or→ to select UPPER, then press ↑ or ↓ to move the top of the bar to the desired depth. 4. To set the lower boundary for the Zone Alarm, use ← or→ to select LOWER, then press ↑ or ↓ to move the bottom of the bar to the desired 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.
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.
If you do experiment with chart speed, remember to reset it to maximum when you resume trolling or moving across the water at higher speed. To change chart speed: 1. From the Sonar Page, press MENU|↓ to CHART SPEED|ENT. 2. The Chart Speed Control Bar appears. Press ↓ to decrease chart speed; press ↑ to increase chart speed. 3. When it's set at the desired level, press EXIT. Contrast See the entry in this section for Screen Contrast and Brightness.
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 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.
There are several fish symbol sizes. These are used to designate the relative size between targets. In other words, Fish I.D. displays a small fish symbol when it thinks a target is a small fish, a medium fish symbol on a larger target and so on. The sonar'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.
Fig. 1 A Many fish arches visible Fig. 2 A Fish arches above structure Fig. 1 B Fewer fish symbols visible Fig. 2 B No fish shown FasTrack graph confirms fish above structure At left, figures 1A and 2A show Sonar Page in normal chart mode. At right, figures 1B and 2B show the same underwater scene with Fish I.D. turned on. Note how arches are replaced with symbols. To turn the Fish I.D. feature on: 1. From the Sonar Page, press MENU|↓ to SONAR FEATURES|ENT. 2.
FishTrack The FishTrack feature shows the depth of a fish symbol when it appears on the display. This lets you accurately gauge the depth of targets. This feature is available only when the Fish I.D. feature is on. The default setting for FishTrack is off. To turn on FishTrack: (Note: These instructions will turn on FishTrack and Fish I.D. at the same time.) 1. From the Sonar Page, press MENU|↓ to SONAR FEATURES|ENT. 2. Press → ↓ to FISH ID DEPTHS|ENT|EXIT|EXIT.
The normal mode of operation (with FishReveal turned off) shows the weakest echoes as black and the strongest echoes in light gray. Since all weak echoes are black, fish arches show boldly against the white background. The drawback is that all weak echoes – such as thermoclines – are also emphasized. This can make it hard to distinguish fish signals inside thermoclines or other cover. In FishReveal mode, the weakest echoes are white and the strongest echoes are black.
Fish not visible Visible fish Fish arch Fish arches Sonar chart in regular grayscale mode, left, and in FishReveal mode, right. Notice how shallow fish formerly hidden in the surface clutter become visible in FishReveal mode. NOTE: Water conditions vary greatly, and that affects sonar performance. Under certain conditions, FishReveal will show you more fish than normal grayscale mode, but the reverse will be true in other circumstances.
all sonar units typically read deeper in fresh water than in salt water.) There is a common exception to these rules of thumb. Some fishermen on freshwater lakes (or the ocean) using downriggers like to see them on the sonar. In many of those cases, you'll see a 50 kHz transducer frequency in use because the wider cone angle lets them watch the bait. Sonar Features menu with a frequency of 200 kHz selected. To change the frequency setting to 200 kHz: 1.
Grayline is adjustable. Experiment with your unit to find the Grayline setting that's best for you. To adjust the Grayline level: 1. From the Sonar Page, press MENU|↓ to GRAYLINE|ENT. 2. The Grayline Control Bar appears. Press ↓ to decrease Grayline; press ↑ to increase Grayline. 3. When it's set at the desired level, press EXIT. Fig. 1A Fig. 1B Hard structure Fish near structure Grayline Fig. 2A Fig.

The "A" figures to the left show locations with Grayline set at the factory level of 64 percent. At right, the "B" figures show the same locations with Grayline increased to 84 percent. In Figure 1B, no fish are near the left structure, but the right structure shows fish holding next to the structure.
At left, we scrolled down the data list to highlight "Water Speed." At right, data list showing "Water Speed" selected to display on Sonar Page. 3. To return to the previous page, press EXIT|EXIT. To turn off displayed data: 1. Press MENU|↓ to OVERLAY DATA|ENT. 2. Press ↓ or ↑ to select Data Type|ENT. The selected data type disappears from the top of the list and reverts to its previous, unchecked position. (If you wish, you may now use ↓ or ↑ to select other Data Types to turn off.) 2.
1. Press MENU|↓ to OVERLAY DATA|ENT. 2. Press ↓ or ↑ to select Data Type|press → or ← to select Data Size|ENT. The data will be shown in the new font size. To return to the previous page, press EXIT|EXIT. NOTE: Some data types can be displayed in only one font size. If that is the case, the Data Size box will not be displayed for that data type. Sonar chart with Overlay Data turned on. This example shows Depth, Water Temperature and the Water Speed of the boat.
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.
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.
Reset Water Distance The sonar chart's Digital Data display option includes a window that shows distance traveled, called Water Distance ("W Distance"). This information is calculated from an optional water speed sensor. The Water Distance window can be reset to zero using the Reset Water Distance command. 1. Press MENU|MENU|↓ to RESET WATER DISTANCE|ENT. The menus are cleared and the water distance is reset to 0.00. Screen Contrast and Brightness To access the Screen menu, press MENU|MENU|ENT.
best sensitivity level shows a good solid bottom signal with Grayline and some surface clutter. Automatic Sensitivity The default sensitivity mode is automatic. The unit bases the sensitivity level on water depth and conditions. When the unit is in the automatic mode, sensitivity is automatically adjusted to keep a solid bottom signal displayed, plus a little more power. This gives it the capability to show fish and other detail.
To adjust sensitivity in manual mode: 1. First, turn off Auto Sensitivity: from the Sonar Page, press MENU|↓ to AUTO SENSITIVITY|ENT. 2. Press ↑ to SENSITIVITY|ENT and the Sensitivity Control Bar appears. Press ↓ or ↑ to pick a different sensitivity setting. When it's set at the desired level, press EXIT. To turn Auto Sensitivity back on: 1. From the Sonar Page, press MENU|↓ to AUTO SENSITIVITY|ENT|EXIT.
feature eliminates the need for the navigator to mentally calculate how much water is under his keel. Keel Offset lets you calibrate the digital depth: chart depth scale, chart cursor depth and fish symbol depth displayed on the screen. To calibrate the depth indicators, first measure the distance from the face of the transducer to the lowest part of the boat. In this example, we will use 3.5 feet. This will entered as a negative 3.
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.

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.
Surface clutter In the illustration at left, Surface Clarity is turned off. The right view shows Surface Clarity set at High. Units of Measure This menu sets the speed and distance (statute or nautical miles, meters), depth (feet, fathoms, or meters) and temperature (degrees Fahrenheit or Celsius).

Pressing ZIN once doubles the size (2X) of all echoes on the screen. Pressing it again quadruples the size of the echoes (4X). The zoom bar on the far right side of the screen shows which echoes will be displayed on the screen when the ZIN key is pressed. For example, pressing the ZIN key once will enable a 2X zoom which will show all echoes that are between the top and bottom of the 2X zoom bar.

Section 5: 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 for repair. For contact information, refer to the last page, just inside the back cover of this manual. Unit won't turn on: 1. Check the power cable's connection at the unit. Also check the wiring. 2. Make certain the power cable is wired properly.
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.
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.
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 unit's power cable and transducer cable away from the wiring that is causing the interference.
Section 6: Supplemental Material FCC Compliance This device complies with Part 15 of the U.S. Federal Communications Commission (FCC) Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the manufacturer could void the user's authority to operate the equipment.
