Track the path of your golf balls while you practice putting! The golf ball will leave a faint track on the surface where the ball rolls. The grooming brush (included) will wipe it away. Features a large 10' long x 18" wide putting surface and the green speed is realistic and the mat lays flat when unrolled. The adjustable wedges allow you to increase the difficulty. Distances are well marked and there are plenty of potential targets (whether on the mat itself or with the putting cups). Roll up, secure with elastic band and store when not in use. Golf balls not included.
