The new Big Bertha Titanium 454 Driver is the biggest Callaway Big Bertha driver ever. The big 454cc size means more hallmark Big Bertha performance: more forgiveness, more confidence, and more distance. The extra large clubhead provides more stability–thanks to a higher Moment of Inertia created by maximizing perimeter weighting–for more accuracy off the tee. Plus an ultra-thin, formed face creates a huge sweet spot that delivers increased ball speed. The new Big Bertha Titanium 454 Driver: the tradition continues.
