Depth Sounder

Depth Sounder

An instrument used to measure the depth of the seabed. Its working principle is that the transmitter transmits a sound pulse to the seabed, and the sound pulse is reflected by the seabed and received by the transducer. In this way, the time difference between the echo pulse and the transmitted pulse is measured, and the depth of the seabed can be directly read through the indicator. The depth sounder can also be used for measurement of inland waterways, reservoirs, underwater projects, etc.
