1. Measuring device for measuring hitting parameters of a golf club, with the measuring system comprising:

  • a) a measurement device, equipped with at least one horizontally directed reflective light barrier,b) a data acquisition device which is integrated into the measurement device,c) reflectors with retroreflective surfaces at the golf club which correspond functionally to the reflective light barrier,d) an information output- and storage unit to which the data acquisition device forwards the acquired measured data,e) whereas the measurement device (3) is arranged opposite to the golfer (9), whereinf) a group of reflectors (7, 7a) is attached to the shaft (25) of the golf club (1) with a tight, but detachable clamp-connection and the group of reflectors (7, 7a) comprises at least two strip-shaped reflectors with retroreflective surfaces (8) and at least three retro-reflective areas (8) are arranged with defined geometry at the golf club shaft (25) and/or at the group of reflectors (7, 7a),g) at least one first reflective light barrier (4) points with its beam (10) at right angle to the ideal swing path (11) of the club head (12) near the tee (13) and/or the golf ball (14) and the three strip-shaped retro-reflective surfaces (8) upon crossing the beam (10) elicits temporally staggered pulse-shaped measuring data, which the receiver of the reflective light barrier (4) receives for forwarding to the data acquisition device (6).
