8.1 Sonar app overview
The Sonar app displays a visualization of the echoes received from a Sonar module and transducer.
The Sonar app is compatible with Traditional, CHIRP, DownVision™, SideVision™ and RealVision™ 3D
sonar modules and transducers. The Sonar app builds an underwater view of bottom structure and
targets in the water column.
Multiple Sonar modules can be connected at the same time. Sonar modules can be internal (built-in
to your MFD) or external (a separate box on your network).
For each instance of the Sonar app you can select which Sonar module and channel that you want to
use, the Sonar module and channel selection will persist over a power cycle.
The Sonar app can be displayed in both Fullscreen and splitscreen app pages. App pages may
consist of up to 4 instances of the Sonar app.
