GOLF GAME

A tee trigger for use in computerized golf games. There is provided an overhead light source which generates a a line of light crossing a tee area in such a way that a ball hit from a line simulating means will break the line of light and reflect light to an overhead photocell to generate a first signal. A second signalling device is spaced from the projected line of light and provides a second signal when the ball reaches that point and the time between the two signals is indicative of the ball's velocity. Through the use of the line of light, the life of the lie simulating means may be increased inasmuch as the ball need not be placed at but a single point thereon for each shot.
