An apparatus for use in training or playing in various shooting games, such as for golf approach shot, baseball batting, or sportive gun shooting. A target screen 12 is provided opposite to a shooting point 16 from which a ball 17 or the like is shot out. Four microphones 101-104 are provided at the circumference of the target screen 12 to detect the collision sound, and another microphone 105 is set at the shooting point to detect the shooting sound of the ball 17. The duration of flight of the ball 17, and the collision point on the screen, and the orbit of the flying ball 17, are calculated by analyzing the detection time points of each microphone in a control part 14. The results, i.e., collision point on the target screen 12, flying orbit of the ball, etc., are shown on a display unit 15. 42
