Excellent compass. Reads within 2 deg. of all my others, so certainly looks to be true. Definately like the mechanical declination adjustment. That should NEVER move once you set it unless you move it. Dial has just the right amount of resistance to prevent unintentional movement. Nice size. Easy to manipulate with light gloves on. Easy to read and quickly find your bearing. The sighting window at the bottom of the mirror is a nice touch. As others have mentioned, the cover takes some pressure to snap shut, but stays closed tight without movement.
