Sonar Sonar When connected to an optional Garmin GSD 22 sounder module and a transducer, your chartplotter can be used as a fishfinder. The GSD 22 connects through the Garmin Marine Network and shares sonar data with every chartplotter connected to the network. Sonar Views The chartplotter shows sonar data using three different views: a full-screen view, a split-zoom view, and a split-frequency view. Full-screen Sonar View The full-screen sonar view shows a full-view graph of sonar readings from a transducer. The range scale along the right side of the screen shows the depth of detected objects as the screen scrolls from the right to the left. From the Home screen, select Sonar > Full Screen.
