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