VRF PACK - NAC-3 + PRECISION 9 COMPASS
Description
NAC-3 Autopilot Core Pack
This pack includes the Simrad NAC-3 autopilot computer, Precision-9 solid-state compass, plus all cabling and connectors required to build an NMEA 2000® network backbone or connect your autopilot system to an existing NMEA 2000® network. This pack is recommended for outboard and sterndrive boats greater than 10 metres (35 feet) in length, and is suitable for use with high-current drive pumps including the Simrad RPU160 and RPU300, mechanical drives such as the Simrad DD15, hydraulic linear drives such as the HLD2000 series, and solenoid valves.
Choose from a range of dedicated autopilot controllers, or control your autopilot from your existing Simrad multifunction display. Install extra autopilot stations, ideal for dual-helm vessels, or add the Simrad WR10 wireless remote for instant steering and autopilot control from anywhere on board.
Simrad Virtual Rudder Feedback (VRF) technology eliminates the need to install a mechanical rudder feedback unit aboard outboard and sterndrive (inboard/outboard) boats. VRF technology greatly simplifies autopilot installation, while delivering uncompromising Continuum steering performance. Industry-standard NMEA 2000® networking and NMEA 0183® input allow simple connectivity to sensors, autopilot controllers, and multifunction displays located anywhere on board. Auto-tuning simplifies setup and ensures optimal steering performance, while automatic compass calibration continuously improves heading accuracy as you travel.
The 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.
- Heading, Rate Of Turn (ROT), roll, and pitch output over NMEA 2000®
- Heading and ROT calculated using sensor data from 9 axes of rotation and motion
- Accurate and reliable solid-state sensor technology
- Heading accuracy of ±2° after calibration
- Easily adjustable mounting bracket allows bulkhead or up-mast installation
- IPX7 waterproof. Best in class.
- Simple installation with a single NMEA 2000® connection
