Abstract
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.
