If you are like me and you LOVE the outdoors, than one of your MOST important tools to always have with you is a compass. Especially if you hike and camp alot. Sure I always take my camera with me, since I'm a photographer, but I always go out prepared and make sure I have the right gear with me at all times.
Its important to me enjoy my adventures that offer me my great photo ops, but its also important to me that I get back home safely in one piece too.
Sure GPS's are nice, but there are times when they could and do fail, and its always nice to have the knowledge and know how of a basic compass and understanding of maps.There are places that offer classes on this knowledge, and knowledge will mean the difference of finding your way home or becoming lost and needing help from your local Search and Rescue Team.
There are some important features to a compass, one and the most important feature is you will have to set your declination of the area that you are in. Its important because it needs be "calibrated" to the area that you are in. (or will be going in.)
With practice a compass is just as fast as a GPS, but it takes time to be this efficient with one. I'm not that efficient with mine yet, but I take it with me and bust it out on hiking trips to stay accustomed with it.
Even people who have GPS's should carry a good compass as a back up, GPS's can and do sometimes fail they are electronics devices that require electrical power. If for some reason your GPS was not charged all the way before your adventure, than you will need a backup tool to get you where you are going, and back to your original destination of your vehicle (starting point).
So with that said, enjoy the outdoors, and be safe out there while you are out and about.
