HDI
Single transducer Ultrasonic Anti-Fouling System.
 
The HD1 is a single transducer unit that can be installed to protect hulls, drives, rudders, stabilizers, and more. This single transducer system can be combined with other systems to provide broad protection for vessels of any size. The HD1 facilitates an easier installation process compared to larger controllers when installing a transducer in an area where routing signal cables back to a larger central controller is impractical.
