ELECTRONIC DEVICE TO IMPROVE A GOLF SWING ABSTRACT OF THE DISCLOSURE: An apparatus to measure the speed of a golf club head during a detected golf club swing is provided. The intent is that, with practice, the user will have a consistent speed of swing, whereby the user may then be assured of a constant and predictable result from striking a golf ball with any golf club. The apparatus provides means for generating and receiving a radar signal, so that signals reflected from the golf club head when it is in a controlled path beforethe apparatus will be received, which signals are subjected to doppler shift. A mixer is provided to determine the doppler shift, with the output being an audiosignal which is amplified. The resultant audio signal is analyzed to determine the period between any two consecutive similarly directed zero-crossings of the output signal, and upon application of algorithmic calculations and/or analysis which identifies specific signal characteristics and/or changes in specific signal characteristics, further signal processing of a binary stream indicative of the audio signal will be carried out to provide specific information as to the speedof the golf club head on any given swing being measured. Cumulative results may be stored whereby consistency of the swing may be determined, and club for distance or distance for club determinations may be made when a consistent swing has been established.
