Wikipedia
echo sounder
Echo sounding or depth sounding is the use of sonar for ranging, normally to determine the depth of water (bathymetry). It involves transmitting acoustic waves into water and recording the time interval between emission and return of a pulse; the resulting time of flight, along with knowledge of the speed of sound in water, allows determining the distance between sonar and target. This information is then typically used for navigation purposes or in order to obtain depths for charting purposes. Echo sounding can also be used for ranging to other targets, such as fish schools. Hydroacoustic assessments have traditionally employed mobile surveys from boats to evaluate fish biomass and spatial distributions. Conversely, fixed-location techniques use stationary transducers to monitor passing fish. The word sounding is used for all types of depth measurements, including those that don't use sound, and is unrelated in origin to the word sound in the sense of noise or tones. Echo sounding is a more rapid method of measuring depth than the previous technique of lowering a sounding line until it touched bottom.

echo sounder
An echo sounder is a scientific instrument used primarily in marine applications to measure the depth of water below a boat or ship. It operates by emitting a sound pulse into the ocean or sea, then timing how long it takes for the sound wave to return after bouncing off the ocean floor. The distance or depth is then calculated using the speed of sound in water. The details it provides can be used for navigation, mapping of the sea bed, or research purposes.
