Advanced Marine Autopilot System for Precision Steering
The SI-TEX SP-120 Autopilot with Rudder Feedback and No Drive is designed to enhance navigation precision for vessels equipped with hydraulic steering, mechanical steering, or solenoid control. This advanced autopilot system eliminates the need for a separate junction box, streamlining installation by allowing all connections to integrate directly into the control head.
Engineered for optimal performance, the SP-120 utilizes a high-performance 9-axis rate gyro compass to deliver exceptional steering response. It enhances navigation accuracy by incorporating GPS Speed Over Ground (SOG) and Course Over Ground (COG) data, ensuring smooth and efficient course corrections. The intuitive control head features a splash-proof, compact 4.1" x 4.1" LCD display, providing real-time readings of the compass heading, selected heading, and rudder angle.
This autopilot system is designed with user-friendly software for effortless operation and quick heading selection, making it ideal for both seasoned captains and first-time users. The SP-120 also supports NMEA-0183 GPS interfacing, allowing integration with most chart plotters for seamless waypoint steering and navigation route execution.
