The Garmin GPS 24xd HVS pairs multi-band GNSS positioning with an onboard magnetic heading sensor, giving compatible MFDs, instrument displays, and autopilots sub-meter accuracy alongside steady heading data at any vessel speed — right down to near-idle trolling. A 10 Hz update rate keeps radar overlay and MARPA tracking fluid, and IPX7 water resistance means the unit handles spray and submersion without issue.
