Abstract: The device is used for monitoring the drive movement and the accuracy with which the striking surface (16) of a golf club hits a golf ball. It comprises a plate-shaped sensor (18), which can be fastened to the striking surface (16) and by which the point of impact can be located. The sensor (18) is connected by way of signal lines (26) to a measurement and computation circuit (30), which can be detachably fastened to the shaft (12) or the back of the head of the golf club, and which together with a yaw rate sensor (65) and an electrical voltage source is mounted in a housing (28) and during each strike carries out a measurement operation in order to determine coordinates of the point of impact relative to the position of a predetermined reference point (22).

Abstract: A device is used for controlling the accuracy with which the striking face (16) of a golf club strikes a golf ball. It has a plate-shaped sensor (18), which can be fastened on the striking face (16) and by means of which the point of impact can be localized. The sensor (18) is connected via signal lines (26) with a measuring and computing circuit (30), which can be releasably fastened on the shaft (12) or on the back of the head of the golf club, is mounted, together with an electrical voltage source, in a housing (28) and which, in the course of every hit, performs a measuring process for determining the coordinates of the impact point relative to the position of a predetermined reference point (22). A radio module (34), connected with the measuring and computing circuit (30), transmits the results of the measurements to an evaluating device (36), like a cell phone or the such, for the program-controlled evaluation and display of the results of the measurements on a display screen (40).
