The AP70 Mk2 is a dedicated autopilot controller designed to meet the needs of professional mariners aboard a variety of commercial vessels.

Replacing both the AP70 and AP80 as our IMO/SOLAS autopilot controller, the AP70 Mk2 retains much of the well-reputed platform of its predecessors, but with a brilliant new display and modernised software interface.

Engineered for responsiveness, robustness and ease of use, the AP70Mk2 pairs a precision rotary control dial with dedicated buttons for instant access to steering modes, several custom-configurable work modes and multiple rudder/thruster integration.
