Echo sounders are used to find fish in the ocean, observe their behavior, and estimate their quantity and size as well as the abundance and distribution of the plankton upon which fish feed. Research vessels and many fishing vessels typically use echo sounders that send and receive signals on up to six frequencies. Norwegian researchers have now developed an echo sounder that works on 100 frequencies simultaneously.
