Sonar; Sonar Views - Garmin GPSMAP 190-01120-00 Owner's Manual

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.
