Selecting a Frequency

Before you can select a frequency, you must open the Full Screen page (page 4), the Split Zoom page (page 5), or the Flasher page (page 8).

When using a dual-beam transducer, you can select a frequency of 200 kHz or 77 kHz.

The 200 kHz frequency shows better detail, has a narrower beam, and is typically used in shallower waters.

The 77 kHz frequency has a wider beam, so it can be used to cover a larger area. It can be used as a search tool to locate structure, such as brush piles, and to see more fish.

When you select a frequency on one page, that setting is applied to the other pages.

1.Select MENU > Setup > Sonar Setup > Frequency.

A-Scope

The A-Scope is a vertical flasher along the right side of the Full Screen page that shows the range to targets in real time along a scale. This view expands the most recently received sonar data so that it is easier to see. It can also be helpful in detecting fish that are located close to the bottom.
