Firstly, I would try it with more than just two compasses. We sell compasses where I work and it is not outside the realms of possibility that one of those compasses is faulty. If one or both of them has been near a strong magnet or has been dropped, they could be way off in terms of accuracy. I have seen many of the cheap low grade compasses we sell have different versions of where north is. But when I get out our digital handheld gps with inbuilt compass, the inaccuracies go away.

Is your GPS compass electronic or differential?
also, on the cheap versions you are familiar with, could you replicate this phenomenon (sliding the compass a foot and having close to 180 degree difference?>
I will take you up on this and try it with other compasses.
I will post results when I do it, but I have to get some first.
