Let me second Lori on the GPS. I have backpacked, mountaineered, worked in the woods and explored for over 60 years without ever using a GPS. I learned to use a map and compass and the technique of dead reckoning in the late 40's and have never felt the need for anything else. In case you think I am nothing more than a Luddite, let me assure you, I used to teach use of GPS to students in forestry, range science and wildlife management. This was because the agencies that employed our students wanted that expertise not because it kept them from becoming lost. In fact, more were lost when using the GPS than those using a map and compass. If you take the time to learn to use a map and compass, then a GPS will be useful and a real asset. But, if you can't put yourself on a map, you are lost whether you know it or not.
