The present invention relates to a golf club. It is important to make one surface of a golf club head contact with the center of a ball tangentially when a golfer hits the ball. The margin of error is great because the golfer estimates an angle using the small surface of the golf club head contacting with the ball. To supplement the estimation, a long line can be drawn on the long frame of the golf club like the figure 1, thereby reducing the margin of error. The golfer removes optical illusions caused by the contours of the surrounding scenery by erecting a putter vertically when the golfer estimates the angle of the surrounding field during the final putting. A level installed vertically on the long line can help reduce the error caused by optical illusions. The present invention will help a user to enjoy golf more easily and joyfully. |
