{"product_id":"bps-marine-bps-2-ultrasonic-antifouling-system-12v","title":"BPS Marine BPS-2 2-Transducer 12V Ultrasonic Antifouling System","description":"\u003cp class=\"nvn-hero\"\u003eThe BPS Marine BPS-2 is a two-transducer ultrasonic antifouling system for boats up to 30 feet. It runs on 12V DC and sweeps ultrasonic frequencies through the hull to keep slime and barnacles from taking hold, protecting the bottom plus drives, rudders, and stabilizers. Bond the transducers with the included epoxy kit and let it run.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe BPS-2 is BPS Marine's two-transducer ultrasonic antifouling system, built to keep marine growth off your hull without hauling out for a fresh coat of paint every season. It runs off 12V DC, bonds two transducers to the inside of the hull, and pulses ultrasonic energy through the fiberglass into the thin film of water against the boat. That constant vibration keeps algae, slime, and barnacle larvae from ever getting a grip.\u003c\/p\u003e\n\u003cp\u003eHere's the short version of how it works. The control module drives both transducers through a multi-frequency sweep that runs from 20kHz all the way up to 42kHz. Sweeping across that range matters, because different fouling organisms react to different frequencies, and a single fixed tone tends to leave gaps. The BPS-2 keeps cycling so nothing settles in long enough to attach.\u003c\/p\u003e\n\u003cp\u003eOne BPS-2 covers a hull up to about 30 feet, and it isn't just for the hull itself. You can task the two transducers with protecting running gear too, so drives, rudders, and stabilizers stay cleaner between dives. Got a bigger boat? These systems are designed to be combined, so you add a second or third unit and place transducers wherever growth gives you the most trouble.\u003c\/p\u003e\n\u003cp\u003eNow the honest part, because install is where these systems live or die. Ultrasonic antifouling works best on solid fiberglass under about an inch thick. The transducer has to make clean, direct contact with the laminate, so any voids, thick cored sections, or air gaps will kill the signal before it reaches the water. Metal hulls and heavily cored bottoms are poor candidates. If your boat is solid glass, you're in good shape.\u003c\/p\u003e\n\u003cp\u003eThe BPS-2 ships with an epoxy kit for exactly that reason. Surface prep is everything here. Grind or sand the mounting spot down to clean laminate, follow the epoxy instructions, and let it cure fully before you splash. Do that and the transducers stay put for the long haul. Rush it, and the most common failure we hear about is a transducer letting go after a season or two. Take your time on the bond and you won't have that problem.\u003c\/p\u003e\n\u003cp\u003ePower draw is modest. The system averages about half an amp on 12V, which is nothing when you're plugged into shore power or running the engine. If your boat sits on a mooring or a hook for weeks at a time, pair it with a small solar panel so it can run continuously without pulling your house bank down. Continuous is the point. The BPS-2 does its best work when it never stops sweeping.\u003c\/p\u003e\n\u003cp\u003eA fair question we get is whether this replaces bottom paint outright. For a lot of owners it cuts way back on it. Ultrasonic protection is strongest against the soft stuff, the slime film and early barnacle set that turns into a fuzzy, draggy mess by midsummer. Plenty of boaters run the BPS-2 and stretch their haul-out and repaint intervals well past what they used to manage. Think of it as active, always-on protection that works around the clock while the boat sits, rather than a coating that slowly gives up over the season.\u003c\/p\u003e\n\u003cp\u003eWho's it really for? Cruisers and weekenders on boats under 30 feet who'd rather not deal with a fouled bottom mid-season. Sailors love that it runs quietly in the background off a small solar setup. Powerboat owners like that it keeps the drives and rudder clean, which is where growth costs you speed and fuel. If you keep your boat in the water year-round in a high-growth harbor, this is the kind of gear that pays for itself in scrubbing time alone.\u003c\/p\u003e\n\u003cp\u003eIn the box you get the BPS-2 control module with an integrated power cable, two submersible transducers each with 15 feet of cable, the epoxy mounting kit, and a printed installation and operation manual. Wire the module to a switched 12V circuit, mount and bond the transducers, and you're protecting the bottom from day one. For boaters under 30 feet who are tired of scrubbing slime and picking barnacles off the running gear, it's a clean, low-maintenance way to keep the bottom in shape.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eTwo submersible ultrasonic transducers protect hulls up to 30 feet, plus drives, rudders, and stabilizers.\u003c\/li\u003e\n  \u003cli\u003eRuns on 12V DC with a low 0.5Ah average draw, easy to power from a switched circuit or a small solar panel.\u003c\/li\u003e\n  \u003cli\u003eUp to 60W of transducer output pushes energy through the laminate to disrupt growth at the source.\u003c\/li\u003e\n  \u003cli\u003eMulti-frequency sweep from 20kHz to 42kHz targets a wide range of fouling organisms instead of a single fixed tone.\u003c\/li\u003e\n  \u003cli\u003e15 feet of cable per transducer gives you room to place them where growth is worst.\u003c\/li\u003e\n  \u003cli\u003eEpoxy mounting kit included for a permanent, high-contact bond to solid fiberglass.\u003c\/li\u003e\n  \u003cli\u003eControl module ships with an integrated power cable for a straightforward wire-in.\u003c\/li\u003e\n  \u003cli\u003eExpandable design lets you combine multiple systems to protect larger vessels.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized BPS Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow big a boat will one BPS-2 cover?\u003c\/summary\u003e\n    \u003cp\u003eA single BPS-2 protects a hull up to about 30 feet.
