Humminbird AS GPS NMEA Splitter Cable

Enhance Your Humminbird Setup with Seamless GPS Integration

Whether you're navigating open waters or chasing trophy fish in tight spots, reliable GPS data is the backbone of any serious boating adventure. The Humminbird AS GPS NMEA Splitter Cable steps in as a game-changer for ONIX and SOLIX users, letting you tap into external GPS receivers like the AS GRP or AS GPS HS. This isn't just a wire—it's your ticket to rock-solid positioning and shared data across your marine electronics.

Picture this: choppy conditions where built-in antennas struggle, or the need to feed precise location info to multiple devices on your helm. This splitter cable bridges that gap by connecting your external GPS source directly to your display unit while branching off an extra NMEA 0183 output. No more signal dropouts or compatibility headaches—just clean, dependable performance that keeps you locked on course.

Key Features That Stand Out on the Water

• Plug-and-Play Design: Tailored for ONIX and SOLIX series, it pigtails effortlessly from your unit's GPS port, adding one dedicated NMEA 0183 feed for peripherals like autopilots or radars.
• External GPS Compatibility: Pairs perfectly with high-sensitivity options, boosting accuracy in obstructed areas like canyons or under heavy canopy—ideal for inland lakes or coastal runs.
• Rugged Build: Marine-grade construction shrugs off saltwater spray, UV exposure, and vibration, ensuring longevity season after season.
• Signal Integrity: Maintains full NMEA 0183 protocol fidelity, preventing data corruption that could throw off your charts or waypoints.

Perfect Fit for Your Humminbird Ecosystem

Engineered specifically for Humminbird's flagship ONIX and SOLIX multifunction displays, this cable expands your system's capabilities without custom wiring or adapters. It's a must-have upgrade if you're running advanced setups with multiple sensors or integrating third-party gear that craves NMEA data. Anglers rigging for tournaments know the edge a stable external GPS provides—faster lock-ons, better precision for contour reliance mapping, and redundancy against unit failures.

Simple Installation: From Box to Bow in Minutes

Setting this up is straightforward, even if you're not a wiring wizard. Here's a quick rundown:

1. Power down your ONIX or SOLIX unit and locate the GPS input port.
2. Connect the splitter's main lead to your external GPS receiver (like AS GRP).
3. Plug the splitter's output into your display's GPS port.
4. Branch the secondary NMEA 0183 lead to your chosen device.
5. Power up, configure in your unit's menu, and verify signal strength—boom, you're enhanced.

Pro tip: Test in open water first to calibrate and confirm data flow. This setup shines in multi-screen helms, distributing GPS intel where it's needed most.

Why Boaters and Anglers Swear By This Splitter

Beyond specs, it's about real-world wins. External GPS receivers cut through interference that plagues internal antennas, delivering sub-meter accuracy for precise waypoint navigation and structure scanning. The splitter's extra output means your fishfinder talks seamlessly to engines, VHF, or even onboard computers—streamlining your entire operation. Tournament pros use it for edge-of-legal enhancements, while weekend warriors appreciate the hassle-free reliability that lets them focus on the fish, not the tech.
