JUNRYOKU Putter practice ball for golf practice hard emphasis on sound confirmation putting, equipment, type, SNB-01H

---------------------------------------------------------------------- This is a golf practice ball specifically for putting, supervised by Yuji Kihara of Nippon Sport Science University's Golf Laboratory. There is a stainless steel ball inside a resin ball with a white line in the middle, and it makes a clicking sound when it moves. When you putt correctly, the white line of the ball will trace a straight path to the cup, and the ball inside will make a constant sound. On the other hand, if you putt without hitting the center of the ball, the white line will bend, causing the ball to wave and move a lot, and you will lose efficient rotational power. Try again and again to make sure the ball makes a consistent sound and the center line of the ball is straight towards the cup. [How to use JUNRYOKU] 1. Before placing the ball, shake it two or three times and divide it into approximately equal numbers on the left and right so that the small balls inside are not lopsided. 2. Set the ball so that the white line in the center is straight towards the target (cup). Please practice at a distance of approximately 1.5m ~ 2.5m. 3.Catch the white line at the center of the ball with the center of the putter, and putt so that the white line continues in a straight forward rotation. [Tips for straight and beautiful putting] - Imagine punching through the equator (center) of the ball! ・Do not rub the top of the ball to avoid hitting it. On the other hand, be careful not to blow too much (down blow)! Efficient rotational force is not transmitted. ・If you accelerate or decelerate before impact, it will be difficult to hit the center and you will not be able to get a sense of distance. The small balls inside are the cause of the waves. Keep a constant speed until impact and practice repeatedly to make sure you are putting with the correct stroke. [Precautions when using] *This ball is limited to use with putters, so please refrain from practicing hitting more than 5 meters and use it only for putting practice. *Although we have conducted extensive durability tests, this product is hollow and is susceptible to temperature changes and harsh blows. Pay special attention to temperature changes and hard blows. *Concentrating on the same area may cause it to wear out quickly. *If you hear an abnormal sound when you hit the ball or there are cracks in the ball, please stop using it. *Please refrain from using at temperatures below -5°C as there is a risk of damage. *Do not leave it in a place where the temperature exceeds 50°C as it may deform. *After use, wipe off dirt thoroughly and store away from direct sunlight.
