2.3 Selecting the Equipment Location

Transducer Mounting Location

It is very important that you mount the transducer correctly. The transducer
provides the most reliable readings if it looks into water that is smooth and
undisturbed.
Acoustic noise is always present and these sound waves can interfere with the
operation of the transducer. Ambient (background) noise from sources such as
waves, fish, rain and other vessels cannot be controlled. Carefully selecting the
transducer's mounting location can minimize noise generated by the vessel's
propeller(s), shaft(s), machinery, and other echo sounders. The lower the noise
level, the higher the echo sounder gain that can be used, and the better the
sounder's performance.
