BPS Marine PRO-4 4-Transducer Ultrasonic Antifouling System - 24VDC

The BPS Marine PRO-4 4-Transducer Ultrasonic Antifouling System - 24VDC is purpose-built to protect your vessel's hull, propeller, and underwater metal components from destructive marine growth and biofouling. After years on the water, any serious boat owner knows that zebra mussels, barnacles, and algae accumulation drain fuel economy, reduce speed, and accelerate corrosion—often costing thousands in haul-out cleaning and propeller replacement. This ultrasonic antifouling solution operates silently and continuously, eliminating the need for toxic copper-based bottom paint or frequent manual scrubbing, making it ideal for freshwater and saltwater cruisers, fishing boats, and commercial vessels that demand year-round hull protection.

The four-transducer configuration delivers comprehensive ultrasonic coverage across the entire underwater surface, emitting high-frequency sound waves that disrupt the attachment mechanisms of fouling organisms without harming fish, mammals, or water quality. Operating at 24 volts DC, the system integrates seamlessly with standard marine electrical systems and draws minimal amperage, so it won't strain your battery bank or alternator during extended cruising. The transducers are strategically positioned to eliminate dead zones, ensuring consistent protection on hulls of various sizes and shapes. Unlike passive or chemical barriers, ultrasonic technology works continuously whether your boat is underway or at rest, providing constant defense against settlement and growth during layup periods—a critical advantage for seasonal boaters.

This system suits cruising sailboats, center-console fishing boats, trawlers, and any vessel operating in biofouling-prone waters where hull speed and fuel efficiency directly impact performance and operating costs. Installation requires mounting the transducers to the hull below the waterline and connecting the control unit to 24VDC power—a straightforward retrofit that adds no weight or drag. The compact control module measures 14 x 5 x 14 inches and weighs just 12.55 lbs, fitting easily in engine rooms, lazarettes, or utility lockers without sacrificing valuable storage space. For boaters who value reliability, reduced maintenance downtime, and extended intervals between haul-outs, the BPS Marine PRO-4 represents a proven investment in hull longevity and sustained performance.
