Personally, I hate golf. It’s slow, and takes forever. But this gadget actually makes me want to play a bit, or at least play with a golf ball. I can leave out the clubs and score keeping part.
It’s called RadarGolf. It solves a common problem, people lose their ball and have absolutely no idea where it is. Rather than just getting a new ball and forgetting about the old one, something I’d do, you could use your RadarGolf to find that lost ball.
