Tru-Nord, makes the finest “button” compasses that I have ever used. They are rugged, reliable, and can be compensated for your area’s magnetic declination. Tru-Nord is introducing a new compass face design for 2013 (and going forward) that gives some more detail to the use. The original compass face offered only cardinal directions while the newly redesigned face has degrees marked in increments of 10.
