Autopilot Performance Enhancement
The M81105 provides the essential rudder position feedback that enables your autopilot to make precise course corrections. Without accurate rudder reference data, autopilot systems cannot effectively control steering, resulting in poor course-keeping, excessive rudder movement, and increased fuel consumption. This transducer ensures optimal autopilot performance by providing the control unit with real-time rudder angle information.
SeaTalk Network Integration
SeaTalk/SeaTalk1 Integration: Connects directly to ST60+ Rudder Angle Indicator instruments, providing visual rudder position display at the helm. Multiple instruments can share the signal for comprehensive rudder monitoring throughout the vessel.
SeaTalkng Compatibility: Integrates with modern SeaTalkng networks using an iTC-5 transducer converter (sold separately). This enables rudder angle display on i70, ST70, and ST70+ instruments while maintaining compatibility with advanced navigation systems.
Professional Installation Guidelines
The M81105 mounts directly to the rudder shaft or steering system, providing continuous monitoring of rudder position. The 10-meter cable provides flexibility for installation in various vessel configurations, from small sailboats to large motor yachts. Proper installation ensures accurate calibration and optimal autopilot performance.
Installation Considerations: Mount the sensor where it can accurately track rudder movement without interference from other systems. Ensure cable routing protects against chafing and provides strain relief at connection points.
Replacement & Upgrade Applications
The M81105 serves as both a replacement component for existing Raymarine and Autohelm autopilot systems and as an upgrade component for vessels adding rudder angle indication to their instrument displays. The universal compatibility makes it suitable for retrofitting older systems with modern display capabilities.
