If you want to refine your putting and practise the ball start and your putting stroke, the Perfect Putting Mat is an excellent choice. Many professionals already use this product. Two different-sized holes, one with a standard size and one with a smaller size. The track lines on the mat make it easy to see how the ball rolls all the way to the hole. A smart automatic ball return feature sends the ball back to you, and there is a back stop to catch the balls that go past the holes. With an exclusive wood finish, the putting mat is both stylish and durable. Measures 10-14 on the stimpmeter (depending on underlying surface). Size: L x B: 300 x 37.5 cm.
