Tritech Super SeaKing DST CHIRP Sonar is a digital CHIRP dual frequency sonar capable of operating in Low Frequency or High Frequency modes. When operating in Low Frequency mode the sonar has a true operational range of 300m. Switching to High Frequency mode the same sensor is capable of providing a high definition image at shorter range. It delivers the clearest images available at operating ranges previously unobtainable. CHIRP technology dramatically improves the range resolution compared with conventional sonars. Resolution can be improved by a factor of five times.
