10.6.4 Change the transducer depth

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.
To change the transducer depth:
1. Select Display.
2. Select Setup from the control panel.
3. Select
+ Sounder to display a list of sounder specification options.
4. The Transducer Depth button shows the current setting. Select Edit, then enter
the difference in depth between the water line and the transducer. For example, if
the transducer is 5 ft (1.5 m) below the water line, just enter 5. If you want to check
or change the distance units, (see "Select the small scale distance units" page 73) .
5. The new setting is applied immediately to all the Sounder screens.
6. When you are finished, select – Sounder.
