Real-World Testing: Putting Si-Tex SP-70 Autopilot w/Rotary Feedback f/Inboards to the Test
First Use Experience
My first real test of the Si-Tex SP-70 Autopilot w/Rotary Feedback f/Inboards was a long-awaited tuna run 60 miles offshore. The conditions were mild, with a slight chop and a steady breeze.
Engaging the autopilot was incredibly simple. I steered the boat onto my desired heading, pressed the “PILOT” key, and the SP-70 smoothly took control. Initially, I made small course adjustments to compensate for current, but it locked on and steered admirably for the next four hours.
Extended Use & Reliability
After several months and countless hours on the water, the Si-Tex SP-70 Autopilot w/Rotary Feedback f/Inboards has proven to be a reliable companion. It has endured everything from calm lake cruises to moderately choppy offshore runs.
There are no signs of significant wear and tear on the control unit or the rotary feedback sensor. A quick wipe-down with a damp cloth after each use keeps the system looking like new. It has significantly reduced fatigue on long trips, allowing me to focus on fishing and navigation.
Breaking Down the Features of Si-Tex SP-70 Autopilot w/Rotary Feedback f/Inboards
Specifications
The Si-Tex SP-70 Autopilot w/Rotary Feedback f/Inboards features an ultra-compact, waterproof control unit designed for easy operation. This unit offers simple keypad controls and a large LCD display.
The LCD screen clearly shows heading, course, rudder angle, operating mode, and any error messages. The control unit can be dash-mounted or quickly detached for handheld use.
The system includes a built-in NMEA0183 Loran/GPS interface for course-line navigation. This allows for precise, route-based steering when connected to a compatible GPS unit.
It uses a rotary rudder feedback sensor that provides the autopilot with real-time rudder position data for precise control. Without a drive unit included, ensure your specific vessel’s steering system is supported by the SP-70.
The autopilot offers adjustable sea state and trim controls. These controls along with ten levels of rudder sensitivity, allow for fine-tuning the autopilot’s response to varying conditions.
Performance & Functionality
The Si-Tex SP-70 Autopilot w/Rotary Feedback f/Inboards performs admirably in its intended role, maintaining a consistent course with minimal deviation. The automatic sea state and trim controls do an excellent job of adapting to changing conditions.
While not as feature-rich as higher-end autopilots, the SP-70 offers all the essential functions needed for basic course keeping and route navigation. The power steering mode is handy for maneuvering in tight quarters.
The SP-70’s simplicity is both a strength and a weakness. It is incredibly easy to use but lacks some of the advanced features found in more expensive systems, such as wind steering or advanced pattern navigation.
