After looking an different options for charging a smart phone, maybe not taking one me be a better option all together. The reason I want to bring a phone Is mainly to inform my family that Im ok ever so often, maybe every morning or something. But charging and reception it is kind of a pain, so what about a Gps tracker suck as the "spot" has any body has any experience with one? being a lighter choice(not having to carry anything to charge it with)will it work on the trail? any cons other than extra cost and the fact that I can't really actually "call" any one or use it to read, no maps or apps, etc. will it preform as advertised. Any other info I may not be considering or taking into account?
