发明名称 Training aid for golfer
摘要 A golf ball flight angle demonstration device includes a rigid body including integral first and second simulated golf club heads with bottom sole surfaces extending between heel and toe ends. A first club face is located on the first simulated golf club head on a plane set at a first loft angle. A second club face is provided on the second simulated golf club head on a plane set at a second loft angle that is greater than the first loft angle. The club faces are oriented in relation to one another such that the planes of the first and second faces intersect along a reference line substantially parallel to a line tangent either of the sole surfaces at a reference face centerline extending through either club face.
