Garmin GRF™ 10 Rudder Feedback Sensor 010-11829-00 Brand New Includes One Year Warranty The Garmin 010-11829-00 is a GRF 10 Rudder Feedback Sensor, designed to work with the Garmin GHP 12 navigation system, to provide rudder position feedback and to detect and avoid rudder stops while sailing or boating. The Garmin GRF 10 Rudder Sensor uses a magnetic sensor to relay position information, eliminating friction that causes other types of sensors to wear out. The arm of the Garmin GRF 10 Sailboat Sensor is connected to the rudder of the boat and relays position information through the sensor to the mariner so they know where the rudder is giving sailors an added peace of mind when starting from a stopped position, docking, launching or moving at slow speeds. 010-11829-00 Features Rudder Feedback Sensor Magnetic Sensor Know the Rudder Position Make Smoother Maneuvers Avoid Over-Compensating Save Undue Wear Stress on the Autopilot System
