Golf Center of Gravity Precise Automatic Marker. Missing the hole on a short putt can happen to any golfer. This issue may be related to the center of gravity deviation in the golf ball. If the ball's center of gravity is off, even a correct putting stroke may fail to launch the ball in a straight line toward the hole. This golf ball center of gravity automatic marker spins the ball at high speed to accurately identify the center of gravity distribution line and axis point. Using this information helps improve putting alignment and consistency by accounting for the ball's internal balance. Additionally, it can assist in improving driver performance by identifying the optimal strike point, helping to stabilize ball flight, reduce backspin, and promote more accurate and efficient contact for better distance and trajectory control.
