Displaying the View from Surface to Seabed
You can choose to display the echogram beginning from the water surface instead of the default view from the sensor position. Depending on the type of fishery, this is useful to see the trawl descent from the sea surface to the seabed.
Procedure
Right-click the echogram and click True Mode.
When True Mode
option is activated, the echogram is displayed beginning from the water
surface (1). When the option is deactivated, the echogram is displayed
beginning from the sensor position (2).
