I just use it for basic directions. Such as you know you need to go east to get back to a trail or you know that if you keep going south you will hit the black top. It takes a bit of work to stay on any certain course with one. You have to take readings when you start out, plotting certain landmarks along the way and jotting down coordinates. If you need that detailed a guide to get out of the woods, you should invest in a gps. A compass is best for woods that you are somewhat familiar with.
