The Garmin GPS 24xd combines multi-band GNSS positioning with an integrated magnetic heading sensor, delivering sub-meter location accuracy and reliable heading data at any speed — all through a single NMEA 2000 connection to compatible marine displays, instruments, and autopilots.

Multi-Band GNSS: Provides position accuracy within 1 meter to compatible marine multifunction displays, instrument displays, and autopilots.

Magnetic Heading Sensor: Delivers heading accuracy within 3 degrees, keeping charts, radar overlay, and MARPA stabilized even at low speeds.

High-Sensitivity GPS: A 10 Hz position update rate supplies high-sensitivity position, velocity, and time data for responsive navigation.

Expanded GNSS Support: Accesses four global navigation satellite systems — GPS, Galileo, GLONASS, and BeiDou — for more accurate tracking in challenging conditions than GPS alone.

Multi-SBAS Compatible: Corrects signal measurement errors and provides information on signal accuracy, integrity, continuity, and availability.

Mounting Options: Supports under-deck, pole, and surface-mount installation for flexible placement aboard any vessel.

Water Resistance: Rated IPX7 to handle exposure to the marine environment.
