20 Things You Didn’t Know About Golf Equipment
Over time, and with the advances of modern technology, golf equipment has dramatically changed. Whether it’s the ball, club, grip, shaft or any other piece of golf gear, many rules and considerations apply to each, and these are often unknown or unclear to many golfers. Here are some fun golf equipment rules and facts:
CLUBS & SHAFTS
▪During a round, the performance characteristics of a club must not be purposely changed by adjustment or by another means (Rule 4.1a (3)).
▪ The minimum length of a club must be 18 inches and, except for putters, must not exceed 48 inches.
▪The first steel shaft was invented in 1925.
▪The shaft on a club must twist the same amount in both directions.
▪Although the maximum number of clubs to be used in a round is 14, a player can start the round with fewer than 14 and add clubs during the round, up to the 14-club limit.
