Upgrade your vessel's navigation with the Furuno GP330B, a compact powerhouse that delivers pinpoint accuracy even in demanding marine conditions. Mariners trust this GPS/WAAS sensor for its reliability across fishing boats, yachts, and commercial crafts, ensuring you never lose your way when it matters most.

Precision Positioning for Confident Voyages

At the heart of the GP330B is its 14 parallel-channel receiver—12 dedicated GPS channels paired with 2 WAAS channels—delivering position accuracy down to 3 meters when WAAS is engaged. This isn't just about numbers; it's real-world performance that helps you anchor precisely in crowded bays or track schools of fish without drifting off course. Updates refresh every second, giving you smooth, responsive data feeds right to your chartplotter.

Seamless NMEA2000 Integration

Designed as an NMEA2000-certified sensor, the GP330B plugs effortlessly into your network backbone or drop lines, thanks to its innovative "pin-enabled" termination resistor. No more fumbling with complex wiring—simply connect the included 6-meter cable and you're set. It's a perfect match for Furuno NavNet 3D systems or any NMEA2000-compatible setup, including direct links to Furuno DRS radar units. This plug-and-play simplicity saves hours during installation, letting you focus on the water ahead.

Rugged Build for Harsh Marine Environments

Built tough with an IP56 waterproof rating, the GP330B shrugs off spray, rain, and rough seas. Its white deck-mount housing blends discreetly on most vessels, while included hardware supports flexible deck or mast installations. Low power draw— just 175mA at 12VDC (LEN=3)—means it won't strain your batteries during long outings. Proven in extreme conditions from coastal patrols to offshore adventures, this sensor stands up where others falter.

Quick Startup and Everyday Reliability

Cold starts in under a minute get you fixing positions fast, ideal for those dawn launches or after storage. Space-saving design keeps your setup clutter-free, maximizing deck space for gear or crew. Whether you're navigating tight channels or plotting long-range routes, the GP330B provides the stable, high-speed data your systems crave.

Installation Tips from Seasoned Mariners

Mount it high on the mast for unobstructed sky view, away from metal structures that could block signals. Secure the NMEA2000 cable along existing runs to avoid snags, and always test WAAS lock before heading out—stronger signals mean tighter accuracy. Pair it with a multifunction display for full NavNet synergy, turning raw GPS data into intuitive charts and overlays.

Versatile for Every Vessel Type

From compact center consoles chasing tuna to luxury cruisers crossing oceans, the GP330B adapts to your needs. Commercial operators appreciate its cost-effectiveness and warranty-backed durability, while recreational skippers love the hassle-free performance that enhances safety without complexity.
