Garmin Steadycast Heading Sensor

The Garmin Steadycast Heading Sensor is an essential navigation tool for serious boaters and anglers who demand accurate heading information on their chartplotter display. After years on the water, experienced mariners know that true bow orientation—not magnetic compass deviation or gyro drift—is critical for plotting accurate courses, setting waypoints, and returning to productive fishing grounds. This NMEA 2000 compatible sensor solves that problem by continuously feeding real-time heading data directly to your chartplotter, eliminating the guesswork and ensuring your vessel's icon always points exactly where your boat is actually headed.

Built on proven solid-state magnetometer technology, the Steadycast Heading Sensor delivers heading accuracy of plus or minus 3 degrees—tight enough for navigation precision and reliable enough for repeatable structure fishing. Installation is straightforward: the sensor features an easy NMEA 2000 plug-and-play interface that requires no complex wiring or programming, and initial calibration takes just two simple steps. At only 0.75 lbs, it mounts cleanly on your vessel without adding weight or creating drag, while its robust design stands up to salt spray, vibration, and constant marine exposure that would degrade lesser instruments.

Anglers and boaters who fish offshore, navigate narrow channels, or operate in areas with strong magnetic interference benefit most from this sensor's independent heading source. Whether you're running a multi-function display, autopilot system, or integrated navigation suite, the Steadycast pairs seamlessly with any Garmin chartplotter that supports NMEA 2000 networking. It's the upgrade that transforms basic navigation into professional-grade precision, giving you confidence that every waypoint, track, and course line reflects your boat's true orientation on the water.
