The clearance alarm will take the current depth reading from the
echo sounder and subtract the current depth reading from the
Depth sensor. The calculated depth of the trawl or towed body is
then compared to the alarm limits. Due to the distance between
the vessel and the trawl, you will have ample time to make the
necessary adjustments to avoid damage.
If your Depth sensor is mounted to the headrope, you must
create a manual depth marker. This is made in the
Trawl info
dialogue.
