Abstract

See full text

When golf is being played, the golf swing of a person (60) is decisive for the quality of the stroke. In order to obtain as good a golf swing as possible with a high hitting reliability and with precision, it is necessary to rotate the club with the arms (70) in a positionally fixed fashion about an imaginary axis through the head (68) and upper body (66). In order to monitor said positionally fixed rotation, it is generally necessary to consult a second person. Specifically, independent checking is possible only with difficulty. The object of the invention is therefore to provide a practice device (10) with which it is possible to check the position of the imaginary axis independently and without help from further persons in order to be able to practice the optimum golf swing even on one's own.
