4x Ultrasonic Antifouling transducers
A four-transducer unit designed to enhance antifouling protection for hulls, drives, rudders, stabilizers, and more. Combine with other Hull Shield systems for extended coverage and intensified anti-fouling strength. With four transducer emitters, the HD4 generates ultrasonic signals that effectively disrupt marine fouling. As part of the advanced HD Series, it delivers nearly double the power directly to the transducers, featuring the latest hardware technology for increased effectiveness. The HD4 is tailored for boats between 40 and 50 ft, providing unparalleled biofouling prevention.
