PuttOUT Pro Putting Gates, 3 Pack and protective bag (gate sizes, large 70mm, medium 60mm and small 50mm) Add another level to your putting game with the PuttOUT Pro Putting Gates. With 3 different sizes you can create putting drills to improve your game. The putting gates are the very best accompaniment for indoor and outdoor practice. Place the gates closer for refining start-line, and further away for breaking putts and a whole new target. Practice more, putt less. It's a fact: Your putter is the most used club in the bag. By improving your putting and reducing the number of putts per round you will dramatically improve your score. 1. Adjustable targets, work on starting line, breaking points and target putting. 2. Progressive practice, start with a wider gate and get narrower as you improve.
