Multibeam Echo Sounders - Kongsberg Maritime

Our product range includes models for all water depths and virtually any application. The benefits of multibeam echo sounders are that they map the seafloor by a fan of narrow acoustic beams, thus providing coverage of the bottom. The resulting seabed maps are more detailed than those obtained using single-beam mapping.

The sound travels through the water as pressure waves. When a wave strikes an object like a weed, a rock, a fish, or the bottom, the wave is reflected. The wave is said to echo—just as your voice will echo off a canyon wall. When the reflected sound wave returns the transducer acts as a microphone.
