The Callaway Big Bertha 454 driver is all titanium and all business. The largest driver made by Callaway at the time of its release in 2005, the Big Bertha 454 increased forgiveness and distance, building on previous iterations of the Big Bertha line. The larger head and perimeter weighting that allowed increased the Moment of Inertia to keep the club from twisting when the ball was struck off-center. The thin face provides faster ball speeds for longer drives.
