Golf Equipment

Average golfers are the focus of today’s equipment designers. It seem that in most golfers bags half of them had less than adequate equipment. Yes, some can’t afford the lasts clubs every year but most are just ignorant of what is available. Some players have clubs that are over 10 years old. Golf Digest recognized the dilemma and reviewed over 522 golf clubs, 130 were picked as winners.

When buying golf clubs you should know some of these terms pertaining to equipment:

Bounce: The degree to which the sole of a club angles up and away from the ground plane when the club is in a square setup position. More bounce is better for soft sand and high, lush grass. Less bounce is needed for firm sand and turf.

Bulge: The curvature from heel to toe that corrects spin on miss hits.

Camber: the radius measurements of the sole form front to back or heel to toe.

Center of gravity (CG): A theoretical point that defines the average location of weight in a club head and the internal point about which a object rotates. A low cg helps to launch the ball higher.

Chamfer: A beveled or rounded edge connecting two surfaces.

Coefficient of restitution: Used by manufacturers to refer to spring like effect of a flexing club face. The USGA limit is .83 which is the energy transfer from club head to ball.

Leading edge: The forward edge of the sole, opposite of the trailing edge.

Momentum of inertia (MOI): the measure of a club’s resistance to twisting of off center hits. The USGA limit for drivers is 5,900 grams/centimeters squared.

Relief: The angling or curve up and back of the sole to reduce contact.

Skirt: The perimeter of a club head between the sole and crown.
