8.2.1 Transducer beamwidth

The transducer mounted to the hull of your vessel serves as both a “speaker”

when transmitting, and as a “microphone” when the echosounder is receiving.

Similar to the way a flashlight focuses light, most of the sound from your

transducer is focused downwards with a smaller amount going out to the sides.

The amount of focusing of the sound beam is expressed as a “beamwidth”.
