StarFish 450H Hull-Mounted Sidescan Transducer Head (20m cable)

Product Code : BP00092

StarFish 450H is the affordable high performance hull-mounted side scan sonar which produces spectacular images of the seabed. The compact slim-line sonar design combined with our flexible mounting bracket ensures the system can be positioned correctly on any vessel helping you capture the best images possible.

As the 450H sonar is fixed to your boat it’s accessible all the time, allowing you to monitor the seabed for interesting targets during every journey. With hullmounted systems, you don’t have to worry about snagging a towing cable when surveying in shallow water or high traffic areas making it very simple to operate. This makes it an ideal system for anyone who may need to capture digital images of the seabed on their own.
