Any sound waves that happen to be propagating through the water will bounceoff of any objects that are there. No device is required to make that happen.A system that intentionally generates sound waves underwater, and then receivesand analyzes those that return after bouncing off of something in the water, is aSONAR system.
Sonar navigation uses sound waves; radar navigation uses electromagnetic waves (usually radio eaves).
Sound waves are used as ultra sound for medical investigations, Sonar waves for underwater investigations and depths..
They use a machine
