The MIL 3H is our best compass, and if its good enough for the military, we believe you’ll find it meets your specs as well.
The Tritium compass can be used in total darkness since seven tritium micro lights allow for navigation in low-light conditions and does not require exposure to a light source, as a phosphorescent compass does. It provides both degrees and mil scales. It’s battle tested and is shock, water, sand proof and funtional from -50ºF to +150ºF.

Ships complete with a lanyard, belt clip and nylon case. U.S. made, NSN 6605-01-196-6971.
