Grass Coil With Spiral Trough Measures Golf Drive (Apr, 1931)

Grass Coil With Spiral Trough Measures Golf Drive
GOLFERS can practice driving to their hearts’ content, and win the additional satisfaction of knowing just how far the ball would have gone on an outdoor course if they use the target recently invented by an Englishman. It is shown at the right. The ball is driven through a funnellike opening leading to coiled runways which hold it until it has lost its momentum. There are nine circuits arranged spirally, as shown in the photo. If the ball completes the nine circuits, it represents a drive of 300 yards. Strength of the drive is automatically indicated.
