Know before you buy
The NAC-2 is specifically engineered for boats up to 10 meters (33 feet) in length. It is designed to handle low-current hydraulic pumps, mechanical drives, and solenoid valves within that size range.
While the RF-25 provides highly accurate rudder position data, the NAC-2 does support a virtual rudder feedback option. This is often a simpler setup for outboard and sterndrive boats where physical feedback installation may be difficult.
The Precision-9 uses solid-state technology to provide precise heading, rate-of-turn, roll, and pitch data. This high-quality input allows the B&G Reflex sailing algorithms to make more accurate steering corrections, resulting in smoother and more reliable autopilot performance.
Yes, the NAC-2 uses NMEA 2000® connectivity, which is the industry standard for marine electronics. This allows for seamless integration with your existing B&G displays and other compatible NMEA 2000 devices on your network.
The NAC-2 operates on a 12/24V input. It provides an 8A continuous output and a 12A peak output, making it well-suited for low-current drive pumps and various mechanical steering systems.
