Hemisphere Sonarhead
The Oktopus hemispherical sonar head delivers a spatial image of the underwater world. Applications are found in shallow water: dredging depth gauges, port monitoring and sediment redistribution.
 
Oktopus manufactures a transducer specially for this sonar head.
 
It transmits and receives in the same frequency range as traditional depth sounders. Its special feature is the ability to sense a hemispherical area.
 
The echo signal is received step by step and transmitted to a recording unit.
