1.12.2 Determining the position for the transducer

The CX34/44/54 is a sophisticated piece of electronic equipment, but how well
it will perform under actual operating conditions will be largely dependent
upon the location of the transducer and how it has been installed.
Careful consideration, therefore, must be given to selecting the mounting loca-
tion and on deciding the method of installation that best suits the vessel.
Air bubbles and turbulence caused by the vessel's movement through the
water will seriously degrade the transducer's performance. Therefore the
transducer should be located well clear of any water intake or discharge line
and also clear of any projection along the hull line which might disturb the
smooth flow of water. It is of profound importance for good performance of
the CX34/44/54 that the water flowing over the transducer be free of bubbles
and aeration. If the transducer face is clean but the performance degrades with
increasing vessel speed, then aeration of the water flowing under the trans-
ducer may be the cause of the poor performance.
Due to the varying design of ship's hulls and different operating speeds, there
