Bill,
Refer to post number 3 from Phoenix; the compasses can handle it, bearing in mind that they are not particularly accurate anyway, pointing toward the magnetic pole rather than the true north/south. The dip angle is greatest at the equator I believe, based on a more or less symmetrical magnetic field around the whole globe (perhaps a representation of that field should be on the HU logo?!)
A bigger problem would be if you got close to the magnetic pole while using a compass because then the compass would be showing you that way rather than toward the true north i.e. the magnetic deviation (I mean variation, as per Smitty's post) increases.
