Aerated water can blind an echo sounder by reflecting the ultrasonic
energy. Water near the bow and water near the keel can become quite
aerated. Aeration occurring near the transducer can be minimized by
keeping the transducer mounted away from the keel, and by mounting the
transducer in the after
2/3
of the vessel’s length midway between the keel
and water line, if possible.
Generally, this provides the best compromise
between obtaining aeration-free water and minimizing propeller noise.
Keep in mind that the deeper the transducer protrudes into the water, the
less chance of aeration.
NOTE:
The transducer should not be mounted near any water discharge fittings.
Never position a transducer behind any struts or fittings that may cause
turbulence.
