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 Lowrance sonar/GPS unit.
Whether you're a first time user or a professional fisherman, you'll dis-
cover that your unit is easy to use, yet capable of handling demanding
navigation and sonar tasks.
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 11 sections. This first section is an intro-
duction to the M68 sonar and GPS. It tells you the basics you need to
know before you can make the unit look around and tell you where you
are, or look below the surface to find some fish.
Section 2 will help you install your unit, as well as the transducer (the
most important part of any sonar installation). 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 37 and head
for the water with your 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 or the in-
