Abstract: An electronic tee off device has a plurality of light-emitting diodes of different colors situated at a location where when energized, they are visible to a golfer when the golfer is properly positioned with respect to a golf ball which the golfer is about to drive from a tee. While the golf ball is carried by the tee a preparatory circuit is connected to the plurality of light-emitting diodes for sequentially placing them in a condition remaining unenergized but ready to be energized so that at any given instant the golfer has no way of knowing which particular light-emitting diode is conditioned to be energized. Upon driving the golf ball from the tee, the latter renders an operating circuit operative to energize whichever one of the light-emitting diodes happens to be in the condition to be energized, and this particular light-emitting diode is only momentarily energized so that the golfer, if properly positioned can detect a particular color of the particular light-emitting diode which is energized at the instant when the golf ball is driven from the tee.
