Wellputt have been developing mats to help all golfers to develop and improve their putting in every aspect. The 26ft version is perfect for large houses, garages and training centres to help you dial in your numbers when it comes to long putts. The safe zone of three feet at the end of the mat helps you to achieve an easy 2 putt distance every time, so you can step up to each putt with confidence. The mat comes with a training book which gives you the ability to improve your game in different ways. Pro Speed Mats measure 10/11.5ft on a Stimp Meter.
