An echo sounder uses sound to measure the depth of the sea, and it sends a sound pulse or signal from a ship or survey towfish to the seafloor and back.

Option B is incorrect because it refers to radar and doesn't involve measuring depth. Option C is also incorrect because it refers to radar instead of echo sounder.
