2006 Raymarine C Series Deviation

[RWS]

Message Preview
I just replaced the fluxgate compass (third one in 8 years) on my 2006 A.D. ST 6001 C Series Smart Pilot multifunction radar/autopilot/star wars gizmo.

I choose a better mounting location this time, resulting in a deviation of ONE DEGREE.

After the setup Iran N, S, E, & W at three different speeds, noting the autopilot setting vs. GPS COG vs. magnetic compass setting.

Base don the numbers below should I add (or subtract) a couple of degrees or just leave well enough alone?

Thank you,

RWS

Is your GPS and auto pilot interfaced? If not, don't mess with it. All three headings are coming from different sources. I use my auto pilot only to go in a straight line after I get her on the course I want. With set, drift, current, wind, ect... you will be hard pressed to get all three to read the same heading
