Compass! I don't really need it because i know our property like the back of my hand. I think it's more a piece of mind type thing for me than anything else. We do have lots of swamps that joins our property that i've never been in and it's never happened before but if a deer was to ever run that far and you have to track deep in those swamps i want to be able to get out of there. No telling what lives in those swamps and i don't care to spend the night in there with the boogy man.
