An echo sounder, or `sonar` in American terminology, is a sound-detecting instrument used to measure the distance between the surface of the water and objects in the water or on the ocean floor. An essential item of navigational and safety equipment, an echo sounder detects objects underwater by emitting a sound pulse via a transducer mounted on the hull or lowered to the required depth and then m...
