[Endorsed by experts] Japan Professional Golf Association "Class A" teaching professional, Daisuke Mitomi is also recommended. Not only for correct swinging, but also for those who want to increase distance. [Correct grip] It comes with a corrective grip and is perfect for beginners. It is also a good opportunity for experienced people to review their grip. [Correct form] The correct swing can be seen by the sound. Even mistakes that are difficult to notice on your own can be told by the sound of a "click". Support for form correction anxiety with sound. [Can be used indoors] The short design and safe structure allow you to practice swinging indoors with peace of mind. Even on days when you can't go outside, you can make progress steadily at home. [Realistic weight] The weight and flex are close to the actual club, reproducing a realistic swing feel. You can feel that swing practice is "useful in actual combat".
