Know before you buy
Multi-band GNSS allows the antenna to track multiple frequencies from satellite constellations simultaneously. This significantly reduces signal interference and improves positioning accuracy to within 1 meter, even in challenging environments.
No, the Garmin GPS 24xd features a built-in magnetic heading sensor. This provides the necessary data to keep your charts and radar overlays stable and aligned, even when your vessel is moving at slow speeds.
A 10Hz update rate means the antenna refreshes your position, heading, and speed data 10 times per second. This provides a much smoother, more responsive experience on your display, which is essential for precise maneuvering and docking.
Yes, the unit is designed for a plug-and-play NMEA2000 setup. It connects directly to your existing backbone, making it compatible with most modern marine electronics systems.
The antenna includes versatile mounting hardware that supports both pole and surface mounting, allowing you to choose the best configuration for your specific vessel layout.
Yes, the antenna carries an IPX7 waterproof rating, meaning it is built to withstand harsh marine conditions, including rain, spray, and temporary submersion.
