The SI-TEX SP38-2 Autopilot Core Pack delivers advanced vessel steering through Intelligent Steering Technology, pairing a flux gate compass and rotary feedback unit with a sunlight-readable 5.7" color LCD head — pump not included. Built for commercial and recreational applications alike, it supports NMEA 2000, Ethernet, and NMEA 0183 connectivity alongside multi-station operation, adaptive sea-condition steering, and optional bow-thruster or Z-Drive interfaces.

Features:

• IST (Intelligent Steering Technology) for superior vessel steering performance
• ADAPTIVE steering that responds to changing sea conditions and vessel speeds
• AUTO-SETUP for automatic drive detection, rudder response timing, and compass detection with calibration
• NMEA 2000, Ethernet, and NMEA 0183 interface connectivity
• Configurable for fishing vessels, offshore boats, workboats, towboats, and yachts
• WORK Mode optimized for fishing boats, towboats, and workboats
• PRC (Proportional Rate Control) for gentle, smooth steering response
• Multi-station capability with security station lock
• Sunlight-viewable 5.7" color LCD display with 9-level backlighting
• LCD display switches to red night palette to preserve operator night vision
