Abstract: A low drag golf club head that provides greater club head speed, increased driving distance, and increased directional accuracy. An air inlet slot located on the front striking face of the golf club head channels air through an internal venturi shaped passage to an air outlet slot located in the wake region at the rear of the golf club head. Drag losses are minimized within the venturi shaped air passage and the air passage is additionally configured to provide a directionally oriented outlet air jet that operates to square the front striking face of the golf club head at and through impact, thereby reducing slices and hooks.
