Practice golf course with greens at different distances - has simple relationship between dia. of each hollow and distance of its centre from common tee

摘要

The ball is driven in succession from each of a number of supports (2) ranged across the tee (1), towards greens (4) of different dia. which increases in proportion to the distance. Each green is a shallow depression in the ground (5) with its centre marked by a small flag (6). The successive lengths of fairway may be e.g. 20,50,100 and 250 m. Electronic devices may be laid in the hollows (4) to signal the impact of the ball. ADVANTAGE - Course occupying small tract of land affords longer drives than in conventional miniature golf.
