One of the benefits of a compass is that it is portable. The slim and compact dimensions of most modern compasses enable you to add one to a pack of any size without worrying about additional weight. Most compasses can fit in your pocket. Some come with straps so you can hang them around your neck or wrist to keep from losing them. When using a compass, you can establish your direction and position on your own. Even if you are alone in the wilderness and far away from a town or even a homestead, as long as you have a compass and an accurate map you can happily navigate across the environment without requiring the aid of another person and without needing an electrical power source.
