The M-Tac Compass Cartographic with Mirror Large is a very practical piece of equipment for the field—simple, but it does exactly what you expect from it. Thanks to the transparent base and 1:25,000 and 1:50,000 scales, it works well with a map and makes orientation easier. The mirror really helps with more accurate direction finding, and the whole thing is lightweight and fits easily in a pocket. It's also nice that there's a lanyard, so you can always have it at hand and not lose it in the field. Overall—a cheap, solid, and very sensible choice for trips, training, or survival.
