I've been looking up something called a gps bracelet from pfo. And it is exactly what is sounds like. A bracelet that works with a gps function. But it's not for finding your way to a destination though, but instead it makes other people close to you like family members be able to track the bracelet wearers location. That way you wont get lost and can get help in case something should happen. So it's a really good invention that little bracelet. I'm definitely going to buy me one of those.
