But the steel in the base plate, frame, housing, refrigerant tank, etc. will have a lot of potential magnetic impact.
I once had a collision when I sat down next to the fluxgate compass built into my tiller pilot with my car keys in my hip pocket. And my 38 will change course if I set my cell phone down near the control head of the wheel pilot(which contains the fluxgate). Small magnetic fields can have big impact id close enough. I suppose you could plan to recalibrate the fluxgate after you have the AC installed, since the magnet effect of the machinery will not be changing position relative to the fluxgate other than the relative position change as the boat heels, and that would minimize the impact on the fluxgate.

Will an air conditioner effect the fluxgate sensor if mounted inches above it in the same locker? The fluxgate is only used when sailing and the air conditioner will be run only at the dock, but I'm not sure if I want to risk it?
