The SI-TEX SP38-17 is the core control pack for the SP38 autopilot system, sold without feedback unit, compass, or hydraulic pump. It centers on SI-TEX's Intelligent Steering Technology (IST) and adaptive steering algorithms that continuously adjust to sea conditions and vessel speed. The sunlight-readable 5.7" color LCD, NMEA 2000/Ethernet/NMEA 0183 connectivity, and multi-station capability with security lock make this a capable foundation for a wide range of commercial and recreational vessel installations.
