The trawl opening size can be selected manually in the GEAR
menu. The trawl depth can also be manually selected, or
automatically if a Simrad FS 3300 or ITI trawl system is
connected to the sonar.
If an echo sounder is connected to the sonar, a white bottom line
will indicate the depth. If an ITI trawl system is connected, the
depth at the trawl will also be indicated.
The depth marker line with depth marker readout can be moved
up and down by the menu joystick, for depth measurements in
the catch data page. The vertical range can be changed by moving
this depth marker to the scale end.
The trawl filling indicators will only operate if an ITI trawl filling
system is connected to the sonar.
The volume estimation of the school is based on the selected type
of fish in the SCHOOL DATA menu. Note that this value can be
adjusted according to experience.
