I live in Northwest Montana and am planning a future hunt, but there is one big hang up, my wife. Being a competent woodsman and Nordic skier, living within walking distance of some of the best wilderness areas in the continental US, I am planning a solo, pack in, mid-winter wolf hunt. But, my wife is a little apprehensive - imagine that. She's worried I will get lost, eaten, injured, avalanched, or worse and the only way I can go is if she can monitor me. I have been looking online for "GPS" trackers and it seems most of them actually use cell phone towers to triangulate position. There aren't cell towers in any of the wilderness areas I've ever been in. The ones I have found that are true GPS seem to be; huge, expensive, short battery life, need a cell phone or computer to operate, or have more features than I need or want. I want a tracker that is: Light Water proof (or that will work through a small Pelican case) Simple (an SOS button would be okay) Battery efficient (I will be gone for 1-2 weeks) True GPS I'm looking for something that will update my position on a topo map every 10min to hour that my wife can see as it is happening. I'm not concerned about privacy.
