SI-TEX SP-80-1 Autopilot w/Rotary Feedback - No Drive Unit

The SI-TEX SP-80-1 Autopilot with Rotary Feedback is a fixed-mount marine autopilot system designed to take the helm and hold course with precision, freeing you to focus on fishing, navigation, or simply enjoying time on the water. This model ships without the drive unit, making it ideal as a replacement control head or for integrating with existing drive systems where only the autopilot controller is needed.

The rotary feedback mechanism ensures accurate course-holding even in variable sea conditions. The SP-80-1 interprets helm input and manages steering commands with the stability serious fishermen and cruising boaters require. Weighing 14 lbs and designed for standard panel mounting at 19 × 6 inches, the unit integrates into existing console installations without excessive space demands. The control interface is straightforward—set your desired course and the autopilot maintains it, eliminating fatigue from hand-steering during long passages or all-day offshore runs.

This autopilot serves weekend anglers making daytime runs to fishing grounds and serious offshore operators managing multi-hour transits in open water. Whether you're positioning the boat while deploying lines, running a grid search pattern, or simply reducing crew workload on a long passage, the SP-80-1 delivers the mechanical reliability SI-TEX is known for in marine electronics. The control head is compatible with external drive units, making it a practical upgrade or replacement component for existing SI-TEX autopilot installations.

SI-TEX autopilot systems have established a solid reputation for holding course in the field. The SP-80-1 controller represents the core brain of that system—compact enough for retrofit, robust enough for continuous duty, and straightforward enough that operators need minimal training to engage and disengage command.
