StpnI actually wish I had one of these on a mountain hike a couple years back. A friend's hat blew off his head and landed on the edge of a cornice. We eventually got it back using a rock and paracord (after screaming at him as he started walking out onto the snow) but it sure would have been easier with something like this. You never know when these gadgets come in handy (others have mentioned geocaching, drones stuck in trees etc.). I don't really understand all the hate in so many of the comments. They're small and lightweight so if I want to keep one in my pack, who cares?
