Transducer

The performance of the fish finder depends upon the transducer position. A place least
affected by air bubbles should be selected since turbulence blocks the sounding path.
Further, select a place least influenced by engine noise. It is known that air bubbles
are fewest at the place where the bow first falls and the next wave raises, at usual
cruising speed. In small, slow-speed boats, the position between 1/2 and 2/3 of the
ship's length from the bow is usually a good place.
Note: The face of the transducer must be facing the sea bottom in normal cruising trim
of the boat.
