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 com- pact, wide-screen, fish finder. First, we want to thank you for buying an Eagle sonar. Whether you're a first time user or a professional f

any longer, turn to the Quick Reference on page 45 and head for the water with your sonar unit!) 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 flip- ping through Section 3 or scanning through the sonar options in Section 4.

The storage temperature range for your unit is from -4 degrees to +167 degrees Fahrenheit (-20 degrees to +75 degrees Celsius). Extended stor- age in temperatures higher or lower than specified will damage the liq- uid crystal display in your unit. This type of damage is not covered by the warranty.

How to Use this Manual: Typographical Conventions Many instructions are listed as numbered steps. The keypad and arrow "keystrokes" appear as boldface type. So, if you're in a real hurry (or just need a reminder), you can skim the instructions and pick out what menu command to use by finding the boldface command text. The fol- lowing 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

For example, instructions for turning on the Fish ID feature would look like this: 1. From the Sonar Page, press MENU|↓ to SONAR FEATURES|ENT. 2. Press → or → ↓ to FISH ID SYMBOLS|ENT|EXIT|EXIT. 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 ri

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 drill- ing 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 de- sired configuration.

optional trolling motor mount uses a one-piece plastic bracket with an adjustable strap. These are "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 installation methods is right for your boat. Remember, the transducer location and installatio

or similar tool for stirring and applying epoxy, and a paper plate or piece of cardboard to mix the epoxy on. Supplies: rubbing alcohol, 100 grit sandpaper, specially formulated epoxy adhesive available from LEI (see ordering information on the inside portion of the back cover). A sandwich hull also requires polyester resin. Selecting a Transducer Location 1. The location must be in the water at all times, at all operating speeds. 2. The transducer must be placed in a location that has a smooth

closer than approximately one foot from the engine's lower unit. This will prevent cavitation (bubble) interference with propeller operation. 5. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps and aerators can be displayed on the sonar's screen. Use caution when routing the trans- ducer cable around these wires. CAUTION: Clamp the trans- ducer cable to transom near the transducer. This will help prevent the transducer f

However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down.) If you fre- quently lose bottom signal lock while running at high speed, the trans- ducer may be c

Typically, shoot-thru-hull installations give excellent high speed opera- tion and good to excellent depth capability. There is no possibility of transducer damage from floating objects, as there is with a transom- mounted transducer. A transducer mounted inside the hull can't be knocked off when docking or loading on a trailer. 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, eve

1. Assembling the bracket. A. One-piece bracket: Press the two small plastic ratchets into the sides of the metal bracket as shown in the following illustration. Notice there are letters molded into each ratchet. Place each ratchet into the bracket with the letter "A" aligned with the dot stamped into the metal bracket. This po- sition sets the transducer's coarse angle adjustment for a 14° transom. Most outboard and stern-drive transoms have a 14° angle. Dot Align plastic ratchets in bracket. B

Aligning the transducer on the transom. A. One-piece bracket: Slide the transducer between the two ratch- ets. 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
