View

Shows a Traditional sonar view or a Flasher view (Flasher View).

Frequency

Adjusts the frequency to adapt the sonar for your particular goals and the present depth of the water.

The 455 kHz setting uses a narrower beam width and is better for rough sea conditions. Bottom definition and thermocline definition can be better when using a higher frequency.

The 260 kHz setting uses a wider beam width, which covers a larger area and can allow you to see more targets, but also could generate more surface noise. Wider beam widths generate larger arches for fish target returns, making them ideal for locating fish. Wider beam widths also perform better in deep water, because the lower frequency has better deep water penetration. They can be used to search for structures such as brush piles.

Scroll Speed

Sets the rate at which the sonar scrolls from right to left. A higher scroll speed shows more detail, especially while moving or trolling. A lower scroll speed displays sonar information on the screen longer.

A-Scope

Displays a vertical flasher along the right side of the screen that shows instantaneously the range to targets along a scale.

Fish Symbols

Sets how the sonar displays suspended targets.

Restore Sonar Defaults

Restores the factory default settings for the sonar view.
