echosounder
Underwater distance measurer
An echosounder is a device that measures water depth by sending sound pulses downward and timing their return from the seafloor.
Ships use echosounders for navigation and to map underwater terrain.
The technology also detects schools of fish: The echosounder showed a large shoal at forty meters.
