In my 'survival pouch', in my 'survival day pack', in the closet of the bedroom (that one is a coincidence). It is in the great company of the knives, a folding saw and metal hand spade......or you think it is wrong?
I see your point and see the potential problem. How long is a compass accurate close to a metal?
JRF, did you check for any electric wire, metal (door frame) close or in the wall?
