Abstract: A measurement setup to determine hitting parameters of a golf club includes a group of reflectors with at least two strip-shaped reflectors with retroreflective surfaces applied to the golf club shaft. The group of reflectors is attached to the club shaft with a detachable, yet tight clamp-connection. At least three retroreflective areas are arranged in a determined geometry at the club shaft and/or at the group of reflectors. At least one first reflective light barrier sends its beam at a right angle to the ideal swing path of the club head near the tee and/or the golf ball at the group of reflectors. During the penetration of the beam the three strip-shaped retroreflective surfaces elicit temporally staggered pulse-shaped signals that the receiver of the first reflective light barrier receives and which it transmits to the data acquisition device. A calibration setup is also provided.
