Lost your balls? Lol. Well, the Ballfinder Scout uses a digital video camera with a color recognition system to find your ball in the rough. They claim it combines digital video camera systems, which makes me think it is not a portable device you can bring anywhere, but I still love the concept.
The company behind this innovation also invented a number of other breakthroughs, which they claim include, "Color TV, Satellite TV, HDTV, and digital TV."
