From the LiveScope or Perspective sonar view, select Menu > Sonar Setup.

Appearance

Configures the appearance of the sonar screen (LiveScope and Perspective Appearance Settings).

Layout

Configures the layout of the sonar screen (LiveScope and Perspective Layout Settings).

Noise Reject

Reduces noise and interference and attempts to remove returns that are not actually targets in the water.

Ghost Reject

Reduces the occurrence of "ghost" images, which are duplicated or reflected images that are not actually targets in the water. "Ghost" images are caused by strong sonar returns, such as the bottom. Shallow water and hard bottoms generally have stronger returns and may cause "ghost" images to occur more obviously.

Adjusting the Ghost Reject and Noise Reject settings together reduces the occurrence of "ghost" images most effectively.

TVG

Adjusts the time varying gain, which can reduce noise.

This control is best used for situations when you want to control and suppress clutter or noise near the water surface. It also allows for the display of targets near the surface that are otherwise hidden or masked by surface noise.

Overlay Data

Sets the data shown on the sonar screen.

Installation

Configures the transducer (Traditional, Garmin ClearVü, and SideVü Transducer Installation Settings).
