Re: Raymarine compass interference

I'm also getting some interference on my compass.

The easiest way to test it is to calibrate the autopilot compass against your regular helm compass in one direction. Put the autopilot compass heading onto the display. Do a slow circle and see if the autopilot compass and helm compass agree in all directions. If not you are getting some magnetic interference.

Ideally the autopilot flux gate compass should be mounted on the centerline of the boat and far from any sources of magnetic interference. It is hard to find the perfect location for that on my boat. I have it mounted under the V-berth, but I'm afraid that it is too close to the water pump (about 2' away).
