Turning On the A-Scope

NOTE: This feature is available in the Traditional sonar views.

The a-scope is a vertical flasher along the right side of the view, showing you what is underneath the transducer right now. You can use the a-scope to identify target returns that may be missed when the sonar data is quickly scrolling across the screen, such as when your boat is moving at high speeds. It can also be helpful for detecting fish that are close to the bottom.


A-scope with callouts

The a-scope above shows fish returns Callout number one and a soft bottom return Callout number two.

  1. From a sonar view, select Menu > Sonar Setup > Appearance > A-Scope > On.
  2. Select a hold time.

    You can increase the hold time to increase the length of time the sonar returns are displayed.
