I was just browsing my own store! HaHa and I stumbled on this item. It's a really neat little gizmo called the RoamEO, I was looking for something like that a while back but I don't think it existed then. It is basically a GPS which allows you to track your dog. The inconvenience I can already see with this is that you have to preset your fence perimeter, so if you ever go to a new location in the woods I don't think it would work. And the price is obviously too expensive. But maybe with time, it will come down. This is probably used for hunting and all, but it would also be nice for hiking and stuff. Here are a few screenshots, more can be found. It really does has some nice features! It even tells you the battery life of the collar (supposable it lasts up to 8-10 hours.) And it can track up to three dogs at the same time. I think this is kind of cool to see how people use technology for stuff like this.
