Garmin Marine Heading Sensor 010-11417-00

For sailors and powerboaters navigating coastal waters, accurate heading data is essential for autopilot performance, radar overlay alignment, and chart stabilization. The Garmin Marine Heading Sensor delivers solid-state heading information with ±3° accuracy, ensuring your marine electronics work in harmony. It connects directly to your NMEA 2000 network with a 6 ft drop cable, drawing power from the bus (9-16 Vdc) and consuming only 150 mA. With an IPX7 waterproof rating and a wide operating temperature range, it withstands the harsh marine environment. The sensor outputs at 10 Hz for real-time responsiveness and supports PGN 127250 for vessel heading. Mount it on any flat surface, keeping it at least 20 inches from compasses and magnetic equipment. Automatic magnetic variation compensation means no manual calibration is required. Ideal for autopilot heading, radar overlay, and chart stabilization on recreational and light commercial vessels.
