Garmin Heading Sensor is a 3-axis compass heading sensor that interfaces with Garmin’s marine MFDs and radars, delivering unparalleled radar overlay performance, precise MARPA capabilities, and dependable operation in the harshest seas.

Powered by a rate gyro, it maintains an exceptional 2-degree heading accuracy under heavy dynamic conditions, with up to 30 degrees of pitch and roll. A 3-axis solid-state compass provides accurate heading data, while a 3-axis accelerometer improves heading, pitch, and roll in static conditions. Temperature compensation across the entire operating range ensures optimum accuracy for every voyage.
