The Garmin Heading Sensor (010-11417-00) is a marine-grade 3-axis compass built for boaters and sailors who need steady, accurate heading data feeding their chartplotters, radar, and autopilot. Based on the proven Airmar H2183 platform, it holds heading better than 1 degree under static conditions and stays within 2 degrees during heavy motion. That stability matters when you're overlaying radar returns or running an autopilot in a seaway. For vessels building out a full instrument stack, this sensor slots in cleanly alongside other NMEA 2000 sensors and feeds the heading reference that radar overlay and MARPA tracking depend on.
Inside the housing is a 3-axis compass paired with a rate gyro, which smooths out the heading signal as the boat pitches and rolls. The sensor tolerates up to 30 degrees of pitch and roll while keeping its 2-degree dynamic accuracy intact, so it doesn't lose its reference when the bow drops into a trough. Output runs over either NMEA 0183 or NMEA 2000, giving you broad compatibility with Garmin marine displays and most networked helm electronics. Mounting is straightforward since the unit fits any angled bulkhead, letting installers position it away from magnetic interference like speakers, wiring runs, and ferrous hardware. That mounting flexibility is one reason this older Garmin unit stayed in service across so many builds. Pair it with a compatible Garmin instrument display to read live heading at the helm.
Most buyers reach for this sensor when they're adding radar overlay, autopilot, or a heading-up chart view to an existing Garmin network and need a fluxgate-class reference that won't drift in a chop. It works equally well on sailboats tacking through swell and powerboats running offshore. If you're comparing newer options, the Garmin SteadyCast uses updated solid-state technology and is worth a look for fresh installs. We carry the related cabling and network hardware to finish the job, including the underlying Airmar H2183 platform and the broader Garmin heading sensor lineup. Reach out if you need help matching it to your existing electronics.
It holds heading accuracy better than 1 degree under static conditions and stays within 2 degrees during heavy dynamic motion. The internal rate gyro keeps the signal stable while the vessel pitches and rolls, which is why it works well as a reference for radar overlay and autopilot input.
Yes. The 010-11417-00 outputs over either NMEA 0183 or NMEA 2000, so it integrates with Garmin marine displays and most networked helm electronics. NMEA 2000 wiring is the simpler route for newer installs and lets the sensor share a single backbone with your other instruments.
The unit maintains its 2-degree dynamic accuracy through up to 30 degrees of pitch and roll. That tolerance lets it keep a reliable heading reference in a seaway without losing its lock when the bow drops into a trough.
The 010-11417-00 is based on the Airmar H2183 fluxgate platform. The newer Garmin SteadyCast uses updated solid-state technology with improved low-speed behavior. For replacing an existing unit on the same network, this model is a direct fit; for a fresh build, compare both.
It fits any angled bulkhead and should be placed away from magnetic interference such as speakers, large wiring runs, and ferrous hardware. Keeping it clear of those sources protects the compass reading and preserves the rated accuracy.
