Callaway 2014 Big Bertha Alpha Driver
Big Bertha is back and in a big way! The Callaway Big Bertha Alpha driver is the first driver from Callaway Golf that allows a player to adjust the Vertical Center of Gravity of the clubhead. The adjustable COG along with adjustable loft settings allows a golfer to adjust launch angle and spin rate independently from one another for a completely fine tuned and optimized ball flight, making it one of the longest drivers in golf! You can’t argue with physics!
