Apparently, according to a land nav guide and teacher, this is one of the best compasses you can buy for the buck. Incorporates the clear bottom for reading the map through the base, a mirror for precise tracking with the passthrough viewport, and a screw-set for the 12 degree offset we are in AZ (or where ever you may be, the degrees offset can be set and adjusted to avoid on the fly math).
