Length: 258cm x Width: 30.8cm x Height: 8.5cm 1. Repeated practice of the basics of putting with an 8cm diameter hole cup The grass on the left side of the hole cup is 10.8cm wide, the same as the actual cup, but the cup itself is slightly smaller, measuring 8cm in diameter. By practicing with this width, you can feel the pressure of an actual putter and improve your putting control and concentration. The return function returns the ball that hits the cup, allowing you to practice repeatedly. 2. 6cm interval guidelines to help you learn the correct launch direction On the right side of the hole cup, two lines are drawn 6cm apart on the grass, and a 5cm cup, roughly the same size as a golf ball, is placed there. By aligning the putter with these lines and "pulling it straight and hitting it straight," you can visualize the direction, which is important when making short putts, and develop consistent putting. White artificial turf is woven into the guidelines. 3. High-density*1 artificial turf recreates bent grass By using high-density*1 artificial turf, we have recreated a ball roll similar to that of the bent grass that accounts for approximately 90% of golf courses in Japan. The Stimpmeter measured 11.8 feet*2, allowing you to experience the ball rolling on a fast green. You can practice repeatedly to hit the ball with the touch that will land it in the target cup.
