WARNING! A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN POSITION INFORMATION. CAUTION When showing navigation data to a position (waypoint), a GPS unit will show the shortest, most direct path to the waypoint. It provides navigation data to the waypoint regardless of obstructions. Therefore, the prudent navigator will not only take advantage of all available navigation tools when traveling to a way- point, but will also visually check to make sure a clear, safe path to the waypoin

Section 1: Read Me First! How this manual can get you out on the water, fast! Welcome to the exciting world of digital sonar and GPS! We know you're anxious to begin finding fish, but we have a favor to ask. Before you grab the 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 combination fish finder and GPS receiver. First, we want to thank you for buying a Eagle sonar/GPS unit. Whether you're a first time user

This section features a one-page Sonar Quick Reference. (If you've al- ready jumped ahead and figured out how to install the unit yourself, and you just can't wait any longer, turn to the Quick Reference on page 50 and head for the water with your unit!) 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, looking it up in the manual's index, just flipping through Section 3 or scanning through the sonar setup options

NOTICE! The storage and operation temperature range for your unit is from -4 degrees to +167 degrees Fahrenheit (-20 degrees to +75 degrees Celsius). Extended storage or operation 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. How Your Sonar Works Sonar has been around since th

You can replay this sonar log in the unit using the Sonar Simulator func- tion. You can save several different sonar log files, erase 'em and record new ones, over and over again. How Your GPS Works You'll navigate faster and easier if you understand how this unit scans the sky to tell you where you are on the earth — and, where you're go- ing. (But if you already have a working understanding of GPS receivers and the GPS navigation system, skip on ahead to Section 2, Installation & Accessories o

Think of this data storage like the hard drive memory in a computer or a tape in a cassette tape recorder. You can save several different GPS data files, erase 'em and record new ones, over and over again. Introduction to GPS and WAAS Well, now you know the basics of how the unit does its work. You might be ready to jump ahead to Section 2, Installation, on page 13, so you can mount your unit and plug in the power. Or you might want to see how our text formatting makes the manual tutorials easy

The system requires signal reception from three satellites in order to determine a position. This is called a 2D fix. It takes four satellites to determine both position and elevation (your height above sea level — also called altitude). This is called a 3D fix. Three satellites are required to determine a 2D fix. Remember: the unit must have a clear view of the satellites in order to receive their signals. Unlike radio or television signals, GPS works at very high frequencies. These signals can

beyond basic GPS. So, the FAA has developed a program to boost GPS performance with its Wide Area Augmentation System, or WAAS. The FAA commissioned the system on July 11, 2003. WAAS is designed to increase GPS accuracy to within 7.6 meters vertically and horizontally, but it consistently delivers accuracies within 1-2 meters horizontal and 2-3 meters vertical, according to the FAA. It does this by broadcasting correction signals on GPS frequencies. Your unit automati- cally receives both GPS a

can skim the instructions and pick out what 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 in- structions: Arrow Keys The arrow keys control the movement of dotted cross-hair lines on your plotter screen called the cursor. The arrow keys also control a horizon- tal line depth cursor on the sonar screen. The arrow keys help you move around the menus so you can execute different commands.

Translated into complete English, step 1 above would mean: "Start on the Plotter Page. Press the Menu key twice. Next, repeatedly press (or press and hold) the down arrow key to scroll down the menu and select (highlight) the My Trails menu command. Finally, press the Enter key." Step 2 would mean: "Press the down arrow key repeatedly to scroll
