2.Qty.:

Model: SFUAS1-01 | Voltage: 12V DC | Coverage: 200 sq.ft per transducer | Frequency: 20–45 kHz adjustable | Waterproof Rating: IP68 Submersible | Included: (1) Ultrasonic Transducer, (1) Control Unit, (1) 15 ft Aviation-Grade Signal Cable | Warranty: 4-Year Limited
[ ADVANCED ULTRASONIC TECHNOLOGY ]: Utilizes high-frequency ultrasonic pulses (20–45 kHz) to continuously repel marine fouling. These vibrations prevent barnacles, algae, and microorganisms from attaching to hull surfaces, significantly reducing drag, improving vessel speed, and enhancing fuel efficienc
[ LARGE 200 SQ FT COVERAGE ]: Each transducer provides approximately 200 square ft of protected underwater surface area. A rough estimate of your underwater surface area can be calculated by doubling your draft, adding it to your beam, then multiplying by your LWL (length at water line)
[ EXTENDS BOTTOM PAINT LIFE & REDUCES MAINTENANCE ]: Keeps hull surfaces cleaner significantly longer, dramatically reducing abrasive hull cleaning frequency and intensity. This substantially extends bottom paint lifespan and protects hull coatings, saving you thousands annually on maintenance, cleaning, haul-outs, repainting, and costly marine upkeep.
[ IMPROVES BOAT PERFORMANCE & FUEL ECONOMY ]: A fouled hull creates drag, reduces vessel performance, and increases fuel costs. SEAFLO’s Ultrasonic Defense System maintains a clean hull, minimizing drag, optimizing speed, and enhancing fuel efficiency, making boating more economical and enjoyable.
[ INCREASED BOAT RESALE VALUE ]: Equipping your vessel with advanced ultrasonic antifouling technology not only protects your investment but also boosts your boat’s resale appeal. Potential buyers recognize the value of reduced maintenance needs and enhanced hull preservation.
[ IP68 SUBMERSIBLE WATERPROOF TRANSDUCER ]: The transducer is built to IP68 standards, fully sealed and capable of continuous underwater operation, ensuring reliable and durable performance even when fully submerged. This rugged construction guarantees consistent protection and reliability under all marine conditions, year-round.

[ FULLY AUTOMATED, EASY DIY INSTALLATION ]: Features automatic calibration and continuous 24/7 operation for effortless antifouling protection. Simple DIY installation requires no special tools or technical expertise, and the included 15-foot aviation-grade signal cable ensures secure, hassle-free connectivity with the control unit.
[ IDEAL FOR Hull, DRIVES & RUNNING GEAR ]: One transducer provides dedicated protection for isolated components like drive shafts, props, rudders, struts, swim platforms, exterior engine brackets, and trim tabs. Because these isolated parts cannot effectively receive ultrasonic signals from the hull, each requires its own transducer for complete and effective anti-fouling protection.
[ BACKED BY SEAFLO’S 4-YEAR WARRANTY ]: Your purchase is confidently backed by SEAFLO’s industry-leading 4-Year Limited Warranty, guaranteeing superior product quality, dependable performance, and peace of mind for your long-term marine antifouling protection.
