BPS Marine BPS-1 1-Transducer Ultrasonic Antifouling System - 12VDC

The BPS Marine BPS-1 1-Transducer Ultrasonic Antifouling System - 12VDC keeps your boat's hull, running gear, and transducers free from marine growth without chemicals or manual scrubbing. After years on the water, any serious boater knows that fouling—zebra mussels, barnacles, slime, and algae—degrades performance, fuel economy, and resale value faster than almost any other maintenance failure. This ultrasonic system solves that problem silently and continuously, protecting your investment while you focus on fishing or cruising.

The BPS-1 uses a single ultrasonic transducer operating on a 12-volt DC power supply to emit high-frequency sound waves that discourage marine organisms from settling on submerged surfaces. Unlike toxic coatings or ionizers that require regular replacement, ultrasonic technology delivers consistent, chemical-free protection 24/7 with minimal power draw—ideal for boats with cruising batteries or integrated marine electrical systems. The compact design (7 x 4 x 10 inches, weighing just 2.8 lbs) installs easily in the bilge or engine compartment, and the transducer mounts directly to the hull or inside the keel cavity where it can reach protected areas that topside coatings cannot.

This system works best on displacement hulls and cruising vessels where speed is moderate and fouling pressure is seasonal or moderate; performance on high-speed planing hulls may vary depending on cavitation patterns. Installation requires a dedicated 12VDC circuit breaker and battery connection, making it compatible with any boat equipped with a standard marine electrical panel. Saltwater anglers, liveaboard cruisers, and boaters in warm or brackish waters see the most dramatic results, often reporting improved fuel economy and cleaner transducers within weeks of activation—a payoff that justifies the modest investment for anyone serious about hull maintenance.
