The Big Bertha line was named after a German cannon during World War I that was known for its accuracy and distance.


The Great Big Bertha II 415 driver is named after the volume of the clubhead, 415cc. It was the largest clubhead that Callaway Golf had ever produced. allowing the weight to be distributed to the edges to keep the shots straight and long. The clubhead was made of titanium and the clubface was manufactured using new methods that made it thinner, stronger and more forgiving on mis-hits. The hosel has been bored all the way through to reduce twisting and improve the weight distribution.
