The Explorist 610 and 710 have a 3 axis magnetometer in them (just like 
iPhones, etc.) and will have the same basic "within a few degrees" 
accuracy like any magnetic compass.

The huge advantage of the electronic compasses is that you don't have to 
hold them level, nor do they need compensation for dip.
