BPS Marine BPS-1 1-transducer Ultrasonic Antifouling System (MPN BPS-1) is a 12VDC preventative system for compatible hulls, drives, rudders, stabilizers and other underwater structures. Manufacturer guidance lists hull coverage up to 20 feet, subject to hull construction, underwater geometry and correct transducer placement.
The controller runs from the vessel’s 12V house-battery system and drives 1 submersible transducer using a multi-frequency 20kHz–42kHz sweep. The package includes one BPS-1 controller with integrated power cable, 1 submersible ultrasonic transducer with 15 ft of attached cable , no separate extension cable listed in the standard package, 1 epoxy kit and a printed installation and operation manual. The hull must be clean before commissioning, and the system is intended to operate continuously.

BPS Marine BPS-1 Reviews
Effective electronic growth protection for hull and running gear
Installed the BPS Marine BPS-1 1-Transducer Ultrasonic Antifouling System (12VDC) on my hull. The high-frequency acoustic waves keep barnacles and algae from bonding to the underwater surface. Power draw on the 12V DC system is minimal, and the transducer mounting instructions were easy to follow.
Easy 12VDC wiring and solid transducer bonding
The kit arrived complete with the control unit, mounting hardware, and clear wiring guides. Bonding the single ultrasonic transducer directly inside the hull was straightforward using recommended epoxy. After 5 months in high-fouling waters, bottom maintenance has been dramatically reduced.
Dramatically reduces bottom paint scrubbing intervals
Product specifications made it simple to confirm that the single-transducer BPS-1 system was the correct coverage size for my boat length. It integrates smoothly into the onboard 12V battery setup, and the hull stays visibly clean without constant diver scraping.
Reliable eco-friendly alternative to heavy antifouling
The BPS-1 system works exactly as advertised by using ultrasonic signal pulses to prevent micro-organism attachment. System status LEDs give clear confirmation that the transducer is active, and power consumption is negligible during extended mooring.
Clear installation guide and top-tier performance
The setup guidance helped identify the optimal transducer mounting position inside the bilge area for maximum acoustic resonance. It has kept the hull and stern area free of hard marine growth all season long.
BPS Marine BPS-1 FAQs
How many transducers are included with the BPS-1?
The package includes 1 submersible ultrasonic transducer, each with 15 ft of attached cable.
What size hull can the BPS-1 protect?
Manufacturer guidance lists compatible hulls up to 20 ft. Final coverage depends on underwater area, construction, geometry and transducer placement.
How much power does the BPS-1 use?
The manufacturer lists a total active draw of 0.25 A for this 1-transducer configuration. Follow the current manual for circuit sizing and protection.
Does the BPS-1 remove existing growth?
No. It is a preventative system. Existing marine growth must be removed before installation and continuous operation begins.
Does ultrasonic antifouling need to run continuously?
Yes. Manufacturer guidance calls for 24/7 operation to help prevent the biofilm from establishing.
Does installation require drilling a thru-hull?
No. The transducers are bonded to suitable internal hull surfaces with the supplied epoxy. Correct preparation and location remain essential.
Can the system protect drives and rudders?
Yes, compatible drives, rudders and stabilizers can be included in the plan. Isolated structures may require dedicated transducer placement.
