I found the ProV while walking the course and put it in play. It found the hole on a elevated tee par 3. We watched it hit in the middle of the green and roll right into the cup. But the best part was that one of my playing partners had a disposable camera in his golf bag. (Now this was before camera phones.). So, I have the ball framed and a picture from the tee and another picture of me taking the ball out of the hole.
