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 aerodynamic's. 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.
A player usually carries several clubs during the game (but no more than fourteen, the limit defined by the rules). There are three major types of clubs, known as woods, irons, and putters. Wedges are irons used to play shorter shots. Woods are played for long shots from the tee or fairway, and occasionally rough, while irons are for precision shots from fairways as well as from the rough. A new type of club called a hybrid combines the straight-hitting characteristics of irons with the easy-to-hit characteristics of higher-lofted woods. A hybrid is often used for long shots from difficult rough. Hybrids are also used by players who have a difficult time getting the ball airborne with long irons. Wedges are played from difficult ground such as sand or the rough and for approach shots to the green. Putters are mostly played on the green, but can also be useful when playing from bunkers or for some approach shots. Putters have minimal loft, forcing the ball to stay on the putting surface when struck.
When on the green, the ball may be picked up to be cleaned or if it is in the way of an opponent's putting line. Its position must first be marked using a ball marker (usually a flat, round piece of plastic or metal, generally a coin).
A tee is an object (wooden or plastic) that is pushed into or placed on the ground to rest a ball on top of for an easier shot; however, this is only allowed for the first stroke (tee shot or drive) of each hole. Conventional golf tees resemble nails with a small cup on the head and are usually made of wood or plastic. Wood tees are generally very inexpensive and quite disposable; a player may damage or break many of these during the course of a round. Plastic tees are generally more expensive and last longer. The length of tees varies according to the club intended to be used and by personal preference; longer tees (3-3.5") allow the player to position the ball higher off the ground while remaining stable when planted, and are generally used for modern woods. They can be planted deeper for use with other clubs but tend to break more often. Shorter tees (1.5-2.5") are suitable for irons and are more easily inserted and less easily broken than long tees.
Alternately, the rules allow for a mound of sand to be used for the same function, also only on the first shot. Before the invention of the wooden spike tee, this was the only accepted method of lifting the ball for the initial shot. This is rarely done in modern times, as a tee is easier to place, hit from, and recover, but some courses prohibit the use of tees either for traditional reasons, or because a swing that hits the tee will drive it into or rip it out of the ground, resulting in damage to the turf of the tee-box. Tees also create litter if discarded incorrectly when broken.
