New for 2022, the Hull Shield HD100 ultrasonic antifouling system provides the most complete and reliable antifouling protection we have ever offered.
The HD100 is a four transducer unit engineered as a stand-alone system which can be used to add antifouling protection to hulls, drives, rudders, stabilizers, and more. When used alone, it can provide ultrasonic antifouling protection for hulls up to 48ft in length, or a combination of 2 drives and 2 rudders when used for drives and stern gear. As with all Hull Shield products, the HD100 can be supplemented with additional systems to provide effective protection for vessels of any size.
Description
About Hull Shield HD4 Ultrasonic Antifouling Controller
The Hull Shield HD4 Ultrasonic Antifouling Controller is an advanced, powerful system designed to protect your vessel’s hull, drives, rudders, and stabilizers from marine fouling. As part of the innovative HD series, the HD4 delivers nearly double the ultrasonic power to four transducers with a high-frequency bandwidth, generating more than twice the frequency bursts compared to prior systems. This makes it highly effective for boats up to 48ft in length or for protecting multiple isolated running gear components simultaneously. Its rugged IP68 waterproof enclosure and IP67 rated connectors ensure durability in harsh marine environments.
Powered by a 12V battery system, the HD4 features smart energy management with automatic power conservation and sleep modes that optimize power use, making it compatible with solar, wind, or traditional battery systems. It automatically reduces power consumption during low battery states and temporarily halts ultrasonic output to preserve essential boat functions like engine starting.
