Welcome to the future of clubhead design with Callaway’s new Epic Flash driver. The clubface, known as Flash Face technology, has not been designed by humans. It has been created by Artificial Intelligence (AI), through machine learning. This is believed to be the first time that this has been used in golf clubface design. The upshot is that the uniquely different face, which has a subtle wave design, allows the golfer to get a greater ball speed at impact which makes the ball fly further for longer distances from the tee. The face itself has been forged from a special titanium which is heat treated for 2 hours to produce a flexible face with excellent strength properties.
