Compass for US troops is required to be a USGI compass. Either
Phosphorus or Tritium, your choice but it must be USGI and not
a knock off. If it does not say Stocker and Yale or Cammenga
on it and have an NSN, it is not USGI.
- You are welcome to bring another type of compass ALSO but
only after you meet the requirement to have a standard USGI compass.
- Look for 1980s dated Stocker and Yale frequently marked SandY
183. They are generally pretty scruffy looking since they did
not use very good paint on the cases but are otherwise very nice
compasses and the tritium has passed it's half life so it is
quite a bit dimmer making these compasses a fair bit easier to
use at night since they are not so wildly bright.
