I bought thing with the intent of eliminating bothersome lensatic compass checks on the move in a tactical setting, but two things were lacking:
1. The reverse numbering system seems good, but when you are tired from running off two hours sleep it just confuses you.
2. Impossible to read in the dark. Doesn't glow in a way that's helpful for actually reading your azimuth. Also the fact that the north seeking arrow is red makes red lense flashlights unhelpful for a quick compass check.
All in all: meh. Save your money and get a basic NSEW, wrist compass that attaches to your wristwatch. It's more helpful.
