Multibeam sonar heads have an array of transducers that simultaneously transmits pings (sound pulses) at a specified frequency to cover a large area in less time than a single beam transducer. To generate
data, computer software assigns a colour range corresponding to the amount of sound reflected off a target. The distance to the target is determined by the length of time it took to receive the transmitted
