Callaway Great Big Bertha II+ ProSeries Driver
The Callaway Great Big Bertha II+ Pro driver has a hot face made of titanium. The face, actually is too hot to conform to USGA rules. This driver was made to be so long that the COR exceeds the limit set by the rules of golf. The neutral weighting in the pro model allows more skilled players to shape their shots off the tee, giving you a deadly combination of distance and accuracy.
