"Golf no Tate-goto" (Golf Harp) is a training aid that Mark Kanai loved at first sight. It's highly effective and is actively used at the Kanda Analyze swing diagnosis site. It helps to perfect the swing plane, which is essential for building a good swing. It brilliantly teaches the relationship between the right and left hands (the feeling of keeping the right hand up). It weighs about one kilogram. The solid weight is effective for building a swing. It allows for a compact top without unnecessary arm movements. And, from the transition, you can learn how to handle your arms like an advanced player (left arm lowering while the right arm extends, finishing while keeping the right hand up). Please judge the condition from the photos and purchase only if you understand and agree.
