Great Big Bertha Tung/Titanium

  - Callaway
Perfect size and weight for exceptional performance under all conditions.

Titanium, combined with a tungsten insert, make a clubhead that is just the right size for use in all conditions – from tee to rough and everything in between. Callaway Golf’s unique tungsten insert represents just 15 percent of the clubhead volume but 40 percent of the weight to keep the clubhead the ideal size and the center of gravity in the ideal location.
