Jayhawk is proud to be the exclusive manufacturer of the DeTerminator. Designed by Jayhawk, in cooperation with leading bowling ball researcher Mo Pinel, the DeTerminator gives pro shop operators previously unseen insight on a ball before drilling it. The DeTerminator will locate the exact position of the mass bias on the surface of the ball and show the ball’s relative motion. It is also the ONLY tool available to accurately locate the mass bias on a plugged bowling ball. With the ability to confidently provide their customers with precise layouts, users of the DeTerminator wonder how they ever ran their pro shops without it.
