Do-it-yourself autopilot packages controlled at your fingertips from a Simrad GO XSE, NSS evo3 or NSO evo2 multifunction display. Affordable automatic steering for engines with hydraulic steering or cable steering. DrivePilot™ delivers robust performance in rough seas with an included rate compass.

Key features:

• Plug-and-play compatibility. Works with both Simrad NAC-1 and NAC-2 autopilot computers.
• Integrated rudder feedback sensor. Eliminates the need for an externally mounted rudder sensor, as the feedback mechanism is built into the unit itself.
• Precise steering. Provides smooth and accurate autopilot control using small, gradual adjustments.
• Easy to retrofit. Supports common steering cables (e.g. Ultraflex M66, Morse 290, Morse 304411, Teleflex SSC52), making upgrades simple.
• Power: Powered by 2–12 VDC supplied by NAC-1
• Power consumption: Motor: Up to 5 A - Clutch: Approx. 0,8 A
• Compass safe distance: 1,5 m (4,9 ft)

How it works in the system HELM-1 works together with the NAC-1 or NAC-2 autopilot computer as the core of the system: NAC-1 acts as the “brain” of the system – it handles signals, steering and the interface to displays or compass sensors. With HELM-1, no external rudder feedback sensor is needed because feedback is built in. It connects with plug-and-play connectors, simplifying installation. Especially useful on boats with limited space or mechanical constraints.
