Common Question of Simrad AC70
What is the AC70 Course Computer?
The Simrad AC70 is a course computer for compatible autopilot steering systems. It processes commands from the controller and heading source to operate a connected drive or pump. Confirm feedback, drive capacity, network, power supply, software, and marine autopilot controller compatibility before installation.
Does it include a pump?
No. The listing identifies the AC70 as a course computer and does not state that a pump, mechanical drive, feedback sensor, heading source, wiring, or control head is included. Confirm complete package contents before purchase.
Does it control an anchor?
No. The AC70 manages compatible autopilot steering and does not operate a gypsy, drum, chain motor, or anchor rope. It is not an electric anchor windlass. Use dedicated equipment for marine anchor retrieval.
