Callaway GREAT BIG BERTHA Driver

Features and Benefits of the Callaway Great Big Bertha driver:

The Great Big Bertha Driver is back, and it represents the next frontier in driver design.
This advanced adjustable driver has a light, fast, stable chassis unlike any other Callaway driver before.
It's a technological breakthrough, and it's built to get the most distance for all golfers.
There's a 10g sliding weight on the perimeter of the clubhead to add stability, and you can slide the weight for more dispersion control to hit your drives on line.
To get every last yard out of your driver Next Gen R-MOTO Technology provides the structure for a thinner face, leading to high ball speeds from anywhere on the clubface.
