Section 1: Read Me First!

How this manual can get you out on the road, fast!

Welcome to the exciting world of digital sonar and GPS! We know you are anxious to begin navigating and 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 compact, color display, combination fish finder and mapping GPS receiver.

First, we want to thank you for buying a Eagle sonar/GPS unit. Whether you are a first time user or a professional fisherman, you'll discover that your unit is easy to use, yet capable of handling demand- ing navigation and sonar tasks. When you team your unit with our cus- tom mapping software MapCreate 6, you have an incredible combina- tion. You will not find another combination GPS and sonar unit with this much power and this many features for this price!

Our goal for this book is to get you on the water fast, with a minimum of fuss. Like you, we would 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:

Section 2 will help you install your unit and the transducer . We'll show you how to get the MultiMedia Card (MMC) correctly installed inside the unit. 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 unit, 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 49 and head for the water with your unit!)
