The transducer depth is the difference in depth between the water line and the location of the transducer on the hull.
The depth column on the extreme right of the Sounder screen shows the DBT (Depth Below Transducer), and not the the depth below the water line.
The default offset is 0. (This default assumes that the transducer is located on the hull at the water line.)
You must enter an accurate value for the transducer depth. If you don't, all the depths on the
Sounder screens will be wrong.
