If you do change the transducer position, re-trace the position of the mounting
bracket before proceeding.

NOTE: It is often necessary to make several incremental transducer adjustments
before optimum high speed performance is achieved. Due to the wide variety of
boat hulls, however, it is not always possible to obtain high speed depth readings.

6. Once you have reached a consistently good sonar signal at the desired

speeds, you are ready to lock down the transducer settings. Force the pivot
to the Up position to gain access to the mounting screws, then re-align the
mounting bracket against the transom of the boat to match the traced
silhouette. Check the bracket position with the level again to make sure it
is still level, then mark the third mounting hole using a pencil or marker.
Unscrew and remove the mounting screws and the transducer assembly
and set aside.
