The flight distance and flight direction of the ball can be calculated easily and with high precision.In other words, a first sound wave detector is installed in contact with the tee cup, and at least four or more sound wave detectors are installed around the target at equal distances from the center. A second sound wave detector is provided, and the initial velocity of the ball is calculated from the time from the time when the first sound wave detector generates an output until the second sound wave detector generates an output, and the ball is converted from the initial speed. This method is characterized in that the flight distance is calculated, and the flight direction of the ball is calculated based on the difference in the output generation time of the second sonic wave detector.

示する。When the counting circuit 9 receives an input from any of the microphones 4, 5, and 6.7, the circuit 9 stops counting pulses and stops the input to the control circuit 10, so the control circuit 10 receives the sent pulses. The speed of the ball 13 is calculated from the number, the flight distance is converted based on the initial speed, and the flight distance is displayed on the display meter 11.
制御回路１０に入るマイクロホン４，５，６゜７からの
入力の時間的ズレによって回路１０はボール１３の飛行
方向を仮定し、表示計１２に方向を表示するものである
。The circuit 10 assumes the flight direction of the ball 13 and displays the direction on the display meter 12 due to the time lag in the inputs from the microphones 4, 5, 6.degree. 7 entering the control circuit 10.

The converted flight distance of the ball can be calculated from the initial velocity, and since the flight direction of the ball is assumed based on the time lag in the output of each microphone caused by the impact sound of the ball hitting the target, the converted flight distance and flight can be calculated using the initial velocity. Direction calculation is easy and highly accurate.
