In mounting a transducer for a depth sounding system, what would represent an ideal location?

Correct Answer: Option D — Mount the transducer forward of the position where the bow wave re-enters the sea.

Transducers must be mounted forward of the bow wave re-entry zone and clear of turbulent boundary layers, hull openings, and propeller cavitation. Placing them in clean, laminar flow ensures uninterrupted acoustic transmission and accurate bottom echo reception free from aeration and acoustic noise interference.
