Cammenga Lensatic Compass 27 - Olive Drab, Phosphorescent

The US Military has been using and issued Cammenga's for decades.  You can trust this compass more than your ability to Land Nav.  

This is the non-Tritium model with phosphorescent paint.  What that mean?  Cheaper (good), also can still be used at night when charge with a quick hit of direct light vs. an always glowing Tritium.  No, it's not ideal where you need 100% light discipline but for most practical purposes, this version will be just fine.  Hide under a tarp if you need to use a light real quick.
