Description

Navico NAC-3 VRF Core Pack – NAC-3, Precision-9 & N2k Starter Kit

Comprising of the high-current NAC-3 Autopilot computer, Precision-9 compass & N2k Starter Kit.

The NAC-3 Autopilot Computer is the brains behind your autopilot system. NAC-3 contains the control algorithms developed to helm a yacht across a broad range of weather conditions and sea-states, alongside the electronics needed to operate a hydraulic or mechanical drive unit, while also interfacing with other components including heading sensors and rudder feedback units. The NAC-3 was designed for boats 10M(33′) or greater in length and is rated to operate high-current hydraulic drives, mechanical drive units, and solenoid valves with a current rating of 30 Amps continuous (50 Amps peak).

Precision-9 Compass
The Precision-9 Compass supplies heading and rate-of-turn information to Simrad, B&G and Lowrance autopilot, radar and navigation systems. Based on reliable solid-state sensor technology, this compact compass offers easy installation aboard any vessel.
