A. Mounting location is very important in maximizing your transducers capabilities. Acoustic noise -- which is always present -- and these sound waves can interfere with the operation of the transducer. While ambient noise cannot be controlled, carefully selecting the transducer mounting location can minimize the effect of vessel-generated noise. The lower the noise level the higher you can set the echosounder gain setting.

Ambient noise sources:
waves and air bubbles, fish and mammals, rain and hail, other vessels, and shores.

Vessel generated noise sources:
aerated and turbulence from water flowing across the hull, propellers, propeller shaft vibration, machinery such as engines, generators, gears, and pumps, as well as interference from other echosounders.
