Used by more than 150 PGA tour professionals, this is the robotic ball return that retrieves practice putts for you. The device fits easily into any standard- or practice-depth golf hole. When a putt drops into the hole, it activates the device's miniature catapult, which returns the ball approximately 14' (depending on green speed). By allowing a two-or three-fold increase in putts, the ball return helps you practice more efficiently, and reduces back strain that can result from repeatedly stooping to pick up balls. An included ball guide redirects errant putts to the hole, ensuring they are returned as well. Comes with a protective case. Requires 4 AA batteries that last for 12,000 putt returns. 1 3/4" H x 3 1/4" W x 33/4" D. (1 1/4 oz.)
