BPS Marine BPS-2 12V Dual-Transducer Antifouling System

BPS Marine BPS-2 (2-Transducer Ultrasonic Antifouling System, 12VDC) adds antifouling protection to hulls, drives, rudders, stabilizers, and more without chemicals. It is designed for boaters with hulls up to 30 feet who want chemical-free, fit-and-forget biofouling protection from two transducer zones.

The system emits high-frequency ultrasonic waves through the hull and drives, creating a microscopic barrier of resonance that repels biofouling before it can attach, entirely chemical-free and safe for marinas with strict environmental regulations. Installation requires no thru-hulls: each submersible transducer mounts directly on top of the hull surface using the included epoxy kit, with 15 feet of signal cable per transducer running to a control module that connects to your boat's existing house battery.
