Upgrade your marine navigation setup with the Garmin GPS 24xd, a compact powerhouse that delivers pinpoint positioning and reliable heading data right where you need it most—on the water. Whether you're cruising coastal inlets, chasing offshore trophies, or maneuvering in tight marinas, this NMEA 2000-compatible antenna stands out by combining multi-band GNSS precision with a built-in heading sensor that performs flawlessly at any speed, including those nerve-wracking slow crawls.

Unlock Next-Level Accuracy for Confident Boating

Imagine gliding through fog-shrouded bays or navigating crowded anchorages without second-guessing your position. The GPS 24xd taps into multiple satellite constellations—GPS, GLONASS, Galileo, and BeiDou—for location fixes accurate to within one meter. This multi-band approach cuts through signal interference from tall buildings, bridges, or heavy tree cover, giving you an edge over traditional single-band receivers that falter in real-world marine environments.

Paired with its magnetic heading sensor, you'll get stabilized charts, radar overlays, and MARPA targets with just 3-degree accuracy. No more erratic compass swings when idling or drifting; your displays stay rock-steady, making it ideal for autopilot integration and precise docking.

High-Speed Data for Dynamic Conditions

With a blazing 10 Hz update rate, this antenna refreshes position, velocity, and time data ten times per second—far smoother than standard 1 Hz units. Fishermen benefit from real-time boat speed and course-over-ground readings during trolling, while sailors appreciate the velocity data for true wind calculations. Multi-SBAS support further refines signals by correcting atmospheric errors, ensuring integrity even in remote ocean stretches.

Built Tough for Harsh Marine Life

Crafted from high-impact plastic alloy and fully gasketed, the GPS 24xd shrugs off saltwater spray, pounding waves, and relentless sun. Its IPX7 rating means it survives submersion up to one meter for 30 minutes, perfect for deck-mounted adventures. Operating from -22°F to 176°F, it handles everything from icy Great Lakes winters to sweltering Gulf summers without missing a beat.

At just 3-19/32 inches in diameter and 1-15/16 inches tall, it slips neatly into tight spaces, blending into your vessel's silhouette.

Seamless Integration and Versatile Mounting

Plug-and-play with NMEA 2000 networks, it connects effortlessly to Garmin chartplotters, multifunction displays, and autopilots. Choose from pole, surface, or under-deck mounts to suit your boat—pole for open flybridges, surface for hardtops, or under-deck for sleeker profiles without drilling visible holes. A 6-meter drop cable and T-connector make wiring a breeze, minimizing clutter in your console.

Pro Tips from Seasoned Boaters

• Placement Matters: Mount high and forward-facing, away from metal structures or engines to dodge magnetic interference and maximize sky view.
• Calibration Routine: Swing your boat in a full circle during setup to calibrate the heading sensor—takes minutes but ensures lifelong accuracy.
• Pairing Power: Combine with radar for MARPA stability or sonar for structure scanning; the fast updates make overlays buttery smooth.
• Maintenance Hack: Rinse with fresh water after every saltwater outing to preserve seals and extend its rugged lifespan.

Boat owners rave about how the GPS 24xd transforms hesitant navigation into intuitive command, especially in GPS-challenged spots like urban harbors or deep canyons.
