Upgrade your Garmin GHP system with the GRF10 Rudder Feedback Sensor cable (sold separately). When paired with the GHP 12™ or GHP20 SmartPump, it delivers precise rudder position feedback and helps you detect and avoid rudder stops during sailing, docking, or slow-speed maneuvers.

• Precise rudder position feedback — The GRF10 uses a magnetic sensor to relay real-time rudder angle to your Garmin system, so you always know exactly where the rudder is.
• Friction-free sensing — Magnetic sensing eliminates mechanical wear and tear, delivering reliable performance over time without the friction of traditional sensors.
• Smarter, smoother maneuvers — Use during docking, starts from a stopped position, or slow-speed sailing to make smoother turns and avoid over-correcting.
• Protects autopilot — Reduces unnecessary rudder movement and force on the autopilot when the rudder is already centered or at rest, extending autopilot life.
• Hands-free rudder awareness — Know the rudder’s position without looking back, increasing safety and confidence on every maneuver.
• Easy installation — The GRF10 arm attaches to the rudder and transmits position information to your Garmin system for instant feedback and peace of mind.

Pair the GRF10 Rudder Feedback Sensor cable with your GHP 12 or GHP20 SmartPump system to enhance control, reduce wear, and sail with greater precision and assurance.
