Garmin GPS 24xd HVS GPS Antenna w/Heading Sensor - NMEA 0183

Upgrade your marine navigation with the Garmin GPS 24xd HVS, a compact powerhouse that delivers pinpoint positioning and reliable heading data right when you need it most—whether you're maneuvering through tight marinas at idle speeds or charting open waters. This NMEA 0183 antenna stands out by combining multi-band GNSS reception with an integrated magnetic heading sensor, ensuring your charts stay steady, radar overlays align perfectly, and autopilot systems respond smoothly even in low-speed scenarios.

Unlock Precision Navigation on Any Vessel

Boat owners know the frustration of signal dropouts in urban waterways or under bridges. The GPS 24xd HVS tackles this head-on with support for multiple global navigation satellite systems, including GPS, GLONASS, BeiDou, and Galileo. This expanded coverage means fewer blackouts and accuracy down to within one meter when paired with compatible chartplotters or multifunction displays. Imagine docking with confidence or running night watches without second-guessing your position— that's the real-world edge this antenna provides.

Heading Stability That Keeps You on Course

At the heart of the GPS 24xd HVS is its magnetic heading sensor, offering accuracy to within 3 degrees. This is a game-changer for stabilizing digital charts, MARPA targets, and radar images, especially when your boat is crawling along at 1-2 knots. Unlike traditional compasses that struggle with magnetic interference from onboard gear, this sensor pulls reliable directional data straight from satellite signals, making it ideal for kayaks, sailboats, or larger cruisers where every degree counts for safe passage.

Rugged Design Built to Battle the Elements

Crafted from high-impact plastic alloy and fully gasketed for IPX7 waterproofing, this antenna shrugs off heavy rain, spray, and submersion up to one meter for 30 minutes. It thrives in extreme temperatures from -22°F to 176°F, so it's ready for foggy mornings in the Pacific Northwest or scorching afternoons in the Gulf. Measuring just 3-19/32 inches in diameter and 1-15/16 inches tall, it blends seamlessly into your setup without adding bulk.

Flexible Mounting for Any Deck Layout

Installation shouldn't be a hassle. Choose from pole mounts for elevated views, surface mounts for flat decks, or under-deck options to keep things sleek and protected. Everything you need comes in the box: pole mount hardware, surface mount bracket, under-deck kit, power/data cable, and an update rate select cable. Connect it to your NMEA 0183 network, and you'll enjoy blazing-fast 10 Hz updates for smoother position, velocity, and time data—ten times per second for ultra-responsive tracking.

Seamless Integration with Your Marine Electronics

Multi-SBAS compatibility fine-tunes signals by correcting errors and monitoring integrity, giving you peace of mind in congested harbors or remote anchorages. Whether you're linking to Garmin autopilots, third-party MFDs, or instrument panels, the GPS 24xd HVS enhances overall system performance. Boaters upgrading from older single-band GPS units often report crisper overlays and fewer recalibrations, turning complex navigation into intuitive cruising.
