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 fisherman, you'll discover that your unit is easy to use, yet capable of handling demanding sonar tasks. You won't find another sonar unit with this much power and this many fea- tures for this price!

Our goal for this book is to get you on the water fast, with a minimum of fuss. Like you, we'd rather spend more time boating or fishing and less time reading the manual!

So, we designed our book so that you don't have to read the whole thing from front to back for the information you want. At the start (or end) of each segment, we'll tell you what content is coming up next. If it's a concept you're already familiar with, we'll show you how and where to skip ahead for the next important topic. We've also made it easy to look up any tips you may need from time to time. Here's how:

The manual is organized into 6 sections. This first section is an intro- duction to the sonar unit. It tells you the basics you need to know be- fore you can make the unit look below the surface to find some fish.

Section 2 will help you install your unit and the transducer. We'll also tell you about some of the available accessories.

Section 3 covers Basic Sonar Operation. It will show you how easy it is to run your sonar, right out of the box. This section features a one-page Sonar Quick Reference. (If you've already jumped ahead and fig- ured out how to install the unit yourself, and you just can't wait any longer, turn to the Quick Reference on page 39 and head for the water with your sonar unit!)
