Using a ProV1 to record my second hole in one on the par 3 8th hole at Cobleskill Golf and Country Club on July 9th, 2020. Tee shot is to an uphill green where you can only see the top of the flag. Playing in a foursome of friends, you can only see the flight of the ball and possibly the first bounce. Just so happened that a twosome witnessed the event from the ninth hole tee box and proclaimed the ball went in the hole as we walked to our carts. My first ace also involved the use of a ProV1 golf ball back in the fall of 2007.
