ABSTRACT:
This invention relates to a golf ball adapted to improve a golfer's score in that the dimples, or cavities, which are aligned on the great circle of the golf ball are provided with diffraction discs whereby the golfer is instantly warned of movement of his eyes and head when looking at the ball while addressing same and executing a golf club swing.
In the game of golf, it is most important for the golfer to rivet his eyes to the ball prior to and during the swing of the golf club. Even the slightest movement of this riveted or fixed gaze upon the ball during the swinging of the club can give unwanted and even disasterous results.
It is an objective of this invention to provide a new and novel golf ball capable of improving a golfer's game.
It is another objective to provide a novel golf ball article of manufacture having diffraction means thereon which indicates, by color change, even the slightest movement of the eyes and head fixed to said ball.
The prior art in the field of novel golf balls is quite extensive and includes Australian Patent 20,780/29 and U.S. Patents 2,861,810 (Veatch); 3,753,565 (Baker); 2,929,631 (Gillon) and 1,795,732 (Miller).
