I never said I would take additional chances with my life...Personally, going into the woods is safer than getting in your car IMO. I have never been worried for myself in the wild, I wasn't sure where I was once, but knowing the terrain by studying a map before going out, having the right tools with me, and growing up in the woods got me home just fine. I don't know that this thing actually navigates for you, but I wouldn't use it if it did, I enjoy landnavigation to much to use a GPS..I would never own one.
What I meant about going out farther was the little extra knowledge that IF anything did happen (broken leg, fall) that I could call for help. You can plan for anything, and be a super hiker, but you can still get hurt. I would think of it as an insurance policy for my kids. I certainly wouldn't rely on it. Thats not my style, and the fact that there are city people getting themselves stranded, or in trouble isn't how I plan for my adventures. I'm not to proud to not use something like that if I had to.
