Sonar views

The FM90i offers three different sonar views: a net opening view, an up-sounder view, and
down-sounder view. The sounder views are shown in windows that can be resized, docked,
or floated anywhere on the display.

How to open

To open the sounder views, click on the up-sounder button or down-sounder button on the
top bar. The net opening view is always available.

Description

The graphical presentation of the net opening view occupies the greater part of the FM90i
presentation. This real-time view is oriented from the cod end towards the bow.
