We used a compass when I would go coonhunting with my friends down in the bootheel of Missouri, fellas there are a bunch of big long deep hollows, in that Mark Twain National Forest. We would generally head out out about 9:00 pm and hunt til about 5:00 am. My friend would hand the compass to me and say dont let us get lost, and we never did, and this is why: When we got ready to leave truck I would take a reading, and coordinate our travel direction from the truck, for instance the truck set in a parking lot at 30 degrees south and we knew that to find this truck at 2:00 am or whenever we would have to use this first reading and triangulate off large topo features and record direction. Large topo features can be anything you can see from a distance like highline poles, lookout towers, cellphone towers, bluffs,,, etc. we called our coonhunting party "lost in the dark"...
