Garmin GRF™ 10 is a magnetic rudder feedback sensor that provides precise and reliable rudder position information, designed for use with Garmin GHP™ 12 autopilot systems. The sensor allows the autopilot to know the actual position of the rudder, thereby detecting and avoiding rudder hard-overs during sailing.
The GRF 10 uses magnetic sensing technology, which eliminates mechanical friction and thus reduces wear compared to traditional rudder sensors. The sensor arm connects directly to the boat's rudder and continuously sends position data to the system, so the rudder's location is always known – even at low speeds, during harbor maneuvers, or when starting up after a stop.
With the GRF 10, you achieve more controlled and smooth maneuvers, as the autopilot can work precisely without overcompensating. At the same time, the autopilot system is protected against unnecessary strain by avoiding pressure on the rudder when it is already at its port or starboard limit. The result is increased comfort, better steering, and a longer lifespan for your autopilot system.
