Excellent compass. Degree markings a bit small, but highly useable. I bought it because it has a good reputation. I paid extra for the 'global' version so I can use it in the Southern Hemisphere (someday....). It's not a compromise, I see no issues arising from this in Northern Hemisphere use. I'm experienced at using a compass: I'm home (from fog on the ocean, mountains, unmarked trails, etc...) I like using a mirror compass because I can more accurately site distant landmarks and use these more accurate angles on my map to find my exact location.  I've got a similar Brunton that is battered after 30 years, this one will outlast me. The angle of declination, the local difference between magnetic north and true north, is set with a small screwdriver attached to the lanyard. This seems a good feature as the setting can't be changed by accident. I don't see any reason if for some reason this little screwdriver is lost that a knife tip or even twig can't be used instead.
