  • Patent number: 5265875
    Abstract: A reduced area, night playable golf course is achieved by utilizing a common driving area for all par 4 and par 5 holes on the course. Separate laterally spaced tees are provided at one end of the driving area for each hole. The ball landing region of the driving area is covered by a grid of ball catching nets having relatively small areas. A ball caught by a particular net is directed to a ball return conduit which includes a ball actuated switch which inputs a signal to a computer which records the distance and lateral position of the ball as two coordinates which are printed on the player's score card. The playing course is conventionally constructed, except that the initial 100 to 150 yards of each par 4 and par 5 hole is omitted. A grid pattern of markers bearing coordinates corresponding to those of the ball catching nets is installed in the initial portions of the par 4 and par 5 holes and the ball is dropped for the second shot adjacent the marker showing the coordinates of the drive.
