It links this sensor with the GHP 12™ to provide rudder position response and detect and avoid rudder stops during navigation. The GRF 10 uses a magnetic sensor to transmit information about the position, eliminating the friction caused by the wear of other types of sensors. The arm of the GRF 10 is connected to the rudder of the boat and transmits information about the position through the sensor to the sailor so that he knows where the rudder is, which gives him greater peace of mind when leaving a position of stopping, docking, starting or moving at reduced speed. In addition, GRF 10 allows sailors to: Know the position of the rudder without having to look back Perform more uniform maneuvers and avoid excessive compensation Reduce unnecessary wear and stress in the autopilot system by eliminating the force at the rudder once stopped to the left or right. FAQs Can you shorten the connecting rod if necessary?Yes, the 300 mm rod can be shortened using a metal saw to suit your installation location. Which hole on the sensor should be used for the ball-joint connector?The second hole from the tip of the sensor is preferred, but other holes may be used based on installation needs. Which hole on the sensor is typically used for the ball-joint connector?Usually the second hole from the sensor tip is used, but other holes may be used based on installation location. What safety equipment is recommended during installation?Wear safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding. What should you check before drilling or cutting during installation?Always check what's on the other side to avoid damaging the vessel. What safety equipment should be used during installation?Wear safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding. What should be checked before drilling or cutting during installation?Always check what is on the opposite side of the surface to avoid damaging the vessel before drilling or cutting. What are the main steps to install the GRF 10 sensor?Key steps: keep rudder centered, align sensor arrows, mark/drill mounting holes, attach ball-joints and mounts, adjust rod length if needed, tighten fittings. How should the connecting rod be positioned?The rod should be installed level or within +/- 5 degrees of level to function properly. What tools are required to install the GRF 10 sensor?A drill with 3.2 mm bit, 8 and 10 mm wrenches, 10 mm socket, metal saw, #2 Phillips screwdriver, tape measure, and pencil are required. What is included in the Garmin GRF 10 package?The package includes the GRF 10 sensor, mounting hardware (M4 screws, M6 locknuts and nuts, washer), tiller arm mount, two ball joint assemblies, and a threaded rod. How is the sensor connected to the autopilot system?The sensor connects via a 12-pin rudder feedback connector to a compatible Garmin autopilot system. What alignment must be ensured during mounting?The sensor and rudder rotation axes must be aligned for correct operation. How long is the connecting rod included with the GRF 10?The rod connecting the sensor to the tiller arm is 300 mm (11.8 inches) long and it can be shortened if needed. What is the maximum range of travel for the sensor?The maximum travel range is 140°, or 70° from center to each stop. Exceeding this may damage the sensor.
