Improve your putting technique over time with a set of 4 PGA TOUR Outdoor Putting Gates which gradually get smaller. Practicing with the gates presents a new challenge to golfers to develop a good swing and consistency of stroke. Train your ability to make it to the hole. On the smallest gate, there is 5mm on each side of the golf ball meaning you need near-perfect alignment and a clear putt. Specially designed for outdoor use on the putting green the variety of widths give a new level of challenge.
