A golf club head enables the initial velocity of a ball to be increased and enables the carry to be lengthened. In some example structures, the golf club includes a face plate formed from metal and club head body (e.g., a crown and sole) formed from fiber reinforced plastic. A weighted body is provided inside the rearmost portion of the golf club head and a low rigidity portion whose width becomes gradually narrower as it approaches the rearmost portion is provided in the crown extending from the vicinity of the face plate to the rearmost portion.

Golf clubs and golf club heads

An instrumented golf club system and methods are disclosed. A variety of golf swing parameters are measured by the instrumented golf club and wirelessly transmitted to a portable computer device. The portable computer device generates a user interface that displays the golf swing parameters against preferred golf swing parameters. The instrumented golf club system allows a golfer to receive feedback in real time while playing golf.
