I've been temporarily misplaced in the past, in the flat scrubby country of outback Australia during summer. I actually new where I was, I was on Ramadel Cattle Station. Only problem was Ramadel covered several hundred thousand acres. Eventually found the truck 14 hours after I set out for a 1 hour walk.
These days carry GPS, Radio, compass & topographic map if hunting remote locations & have not been misplaced since carrying these items. I have had a false position displayed on my GPS, after falling in a creek & submerging the unit, but was able to confirm my position with map & compass.
I have a hunting buddy that we nicknamed "bang bang", cause every second time he comes out deer hunting with us in the mountains ,he gets lost & fires shots to get our attention.
