My buddy and I ended up getting lost when we were hog hunting in Texas a few years ago. Rain settled in, and the temp dropped 15 degrees almost instantly. The tiny bubble compass saved our hides. We knew a road cut through the state game area a few miles south of us, and our truck was parked in the south east corner. Ever since then I always grab it when bombing around new trails. I've been wrapping mine in blaze orange duct tape for marking trails while scouting game areas in Michigan for this upcoming deer season. It's been a handy addition.
