2
Drive the boat at a slow speed. If the chartplotter appears to
be working properly, gradually increase speed while
observing the chartplotter.
3
If the sonar signal is suddenly lost or the bottom return is
severely degraded, note the speed at which this occurs.
4
Return the boat to the speed at which the signal was lost,
and make moderate turns in both directions while observing
the chartplotter.
5
If the signal strength improves while turning, adjust the
transducer so that it extends another

in. (3 mm) below the
transom of the boat.
6
Repeat steps 2–4 until the degradation is eliminated.
7
If the signal does not improve, move the transducer to a
different location on the transom, and repeat the test.
