Turning on the A-Scope

The a-scope is a vertical flasher along the right side of the full-screen sonar view. This feature expands the most recently received sonar data so that it is easier to see. It can also be helpful for detecting fish that are close to the bottom.
NOTE: This feature is not available on all sonar screens.
From the full screen page, select Menu > Sonar Setup > Appearance > A-Scope.
