ABSTRACT:
The present invention relates to a device for training to play golf. Above a black disc is coaxially held a detector comprising a phototransistor which monitors a surface of diameter equal to that of a golf hole less the diameter of a golf ball and which sends to an electronic circuit any variation of light due to the passage of a golf ball, this electronic circuit measures the duration of this variation, comparing it with a predetermined duration and signalling the probability of this ball dropping into a golf hole or passing above it or to the side.
