How to use the trawl symbol
This is a useful aid in providing an overview of the trawl
operation. Trawl data can be set manually using the menu or
automatically by interfacing a Simrad FS trawl sonar or Simrad
ITI trawl monitoring system with the sonar.
In the manual mode the trawl symbol will be displayed with
the selected size, depth and distance. When the FS70, FS900
or FS3000 trawl sonar is connected, the trawl symbol will
automatically be displayed with the correct depth in the vertical
modes. When the ITI trawl system is connected, the trawl symbol
will be displayed with the correct distance, bearing and depth.
If required, the trawl opening, ambient water temperature, and
trawl-lling indicator may also be displayed. This is assumed
that the proper sensors are connected to the ITI system.
