Photo detail

The Big Bertha Alpha has two adjustable weights to give the club a draw or a fade bias. It also has an adjustable hosel that lets golfers independently tweak the loft and the face angle of the club.

Callaway's new Big Bertha Alpha driver is loaded with adjustability.
Unscrewing the plug in the center of the sole allows golfers to adjust a weighted core. Inserting the core with the heavy end in first raises the CG location for a penetrating ball flight; putting the light end in first lowers the CG for a higher ball flight.
The Big Bertha Alpha has been designed with Callaway's new Hyper Speed Face Cup for added ball speed.

The crown is made from a carbon composite material that is extremely lightly, allowing Callaway designers to redistribute the saved weight to performance-enhancing areas in the head.
