Abstract
An improved driver club head for the game of golf including an internal cavity which communicates with a shaped slot in the rear of the head to provide a short-term dynamic alleviation of the base aerodynamic drag of the head when it is being swung. The head can be manufactured from traditional materials such as wood, but in its preferred embodiments, it is constructed from metal or composite materials.
