The SI-TEX SP-120C brings full-color autopilot capability to hydraulic, mechanical, and solenoid-steered vessels under 38 feet. All wiring terminates directly at the control head — no junction box required. A high-performance 9-axis rate gyro compass delivers precise steering response, while NMEA-0183 GPS integration enables waypoint and route following when paired with a chartplotter. The compact, splash-proof color LCD simultaneously displays compass heading, selected heading, and rudder angle, making situational awareness straightforward at a glance. Covered by a 2-year SI-TEX warranty.
