Raymarine M81105 Rudder Reference Transducer
Achieve unparalleled autopilot performance and steering precision with the Raymarine M81105 Rudder Reference Transducer. This essential component is the cornerstone of a responsive and reliable navigation system, providing your autopilot´s course computer with instantaneous, high-accuracy data on your vessel´s rudder position. By constantly monitoring the exact rudder angle, the M81105 enables the autopilot to make subtle, intelligent adjustments, resulting in superior course-keeping, smoother turns, and a more comfortable journey for everyone on board.
Designed for the harsh marine environment, this robust transducer ensures consistent and dependable operation when you need it most. Its feedback allows the autopilot to apply the correct amount of counter-rudder to prevent oversteering, a feature that not only improves the ride but also enhances fuel efficiency by minimizing drag from excessive rudder movements. Whether you are replacing a worn-out unit or completing a new installation, the M81105 is the genuine Raymarine part engineered for seamless integration and long-lasting durability.
