Simrad NAC-3 Autopilot Computer

Virtual Rudder Feedback
Simrad Virtual Rudder Feedback (VRF) technology eliminates the need to install a separate rudder feedback unit aboard outboard and sterndrive (inboard/outboard) boats with planing hulls. This reduces overall autopilot system cost and complexity, and is ideal where a feedback unit is impractical due to mechanical constraints. For vessels that do require a physical rudder feedback sensor, the NAC-3 supports SimNet or NMEA 2000® connected Simrad RF25 feedback units, and rudder feedback sensors with variable frequency output including the Simrad RF300.
 

Easy Installation
Industry-standard NMEA 2000® networking and NMEA 0183® input allow simple connectivity to heading sensors, rudder feedback units, autopilot controllers, and multifunction displays located anywhere on board.
