Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. Golf equipment
encompasses the various items that are used to play the sport of golf.
Types of equipment include the golf ball itself, implements designed for
striking the golf ball, devices that aid in the process of playing a
stroke, and items that in some way enrich the playing experience. The
minimum allowed diameter of a golf ball is 42.67 mm and its mass may not
exceed 45.93 g. Modern golf balls have a two-, three-, or four-layer
design constructed from various synthetic materials. The surface usually
has a pattern of 300-450 dimples designed to improve the ball's
aerodynamics. The method of construction and materials used greatly
affect the ball's playing characteristics such as distance, trajectory,
spin and feel. Harder materials, such as Surlyn, usually result in the
ball's traveling longer distances, while softer covers, such as
Urethane, tend to generate higher spin, more "feel" and greater stopping
potential. Golf balls are separated into three groups depending on their
construction: two-, three-, or four-piece covers. Generally four-piece
golf balls tend to be the most expensive, though price is no assurance
of quality.
