Section 3: Basic Sonar Operation

This section addresses the unit's most basic sonar operations. The in- structions presented here in Sec. 3 follow a chronological order. Sec. 4, Sonar Options & Other Features, will discuss options and other more advanced functions and utilities. The material in Sec. 4 is arranged in alphabetical order.

Before you turn on the unit, it's a good idea to learn about the different keys, the Main Menu, the Sonar Menu, the five Page options and how they all work together. BUT, if you just can't wait to get on the water, turn to the one-page Quick Reference on page 38.
