SI-TEX SP-70 Autopilot w/Rotary Feedback f/Inboards - No Drive

The SI-TEX SP-70 Autopilot with Rotary Feedback for Inboards is a compact marine autopilot system engineered to reduce fatigue on extended cruising and fishing trips. Designed specifically for inboard vessels with hydraulic or mechanical steering, this autopilot delivers hands-free heading control without requiring a separate drive unit, making it an economical choice for boat owners seeking reliable course-keeping without excessive complexity or installation challenges.

The SP-70 features a waterproof control unit with simple keypad operation and a large LCD display for clear heading readout in daylight and low-light conditions. The rotary feedback mechanism provides real-time steering input confirmation, allowing the autopilot to maintain accurate directional control even in variable sea states. At 13.6 lbs with compact dimensions of 19 x 6 x 20 inches, the control unit mounts easily in helm areas without consuming significant space—a practical advantage on boats where panel real estate is limited. The no-drive configuration means the system interfaces with your existing hydraulic or mechanical steering apparatus, reducing installation cost and compatibility issues.

Weekend anglers and serious offshore fishermen benefit equally from the SP-70. Weekend cruisers reduce helm fatigue during long transit to fishing grounds, while offshore operations gain the precision course-holding needed for trolling, drifting, or positioning over structure. Inboard vessels—whether displacement cruisers, trawlers, or larger sportfishers—represent the primary market, though the system's universal steering compatibility (hydraulic or mechanical) broadens its application across many inboard configurations. This autopilot trades the feature complexity of larger systems for straightforward, field-proven operation that prioritizes reliability in salt and freshwater environments.
