Sonar Page, showing full sonar chart mode.

You can customize how the Sonar Page displays its pictures and other data in many ways. Your unit also includes several special sonar features and options that can help you better interpret the underwater scene.

We'll discuss all of those features and options in Sec. 4, but to show you how easy this unit is to operate, the following page contains a simpli- fied, 10-step quick reference that will cover most fish finding situations. The quick reference describes how your unit will operate with all the sonar features in their automatic modes, which are set at the factory.
