The Callaway Great Big Bertha is a 3 component golf clubhead:
The Callaway Golf Tungsten Gravity Screw is less than 2% of the total clubhead volume yet 25% of the total weight. It's precisely positioned to achieve the ideal center of gravity which is extremely low and deep. Callaways unique combination of an extremely low, deep center of gravity and large effective area gives these Great Big Bertha woods true performance advantages.
The Callaway Great Big Bertha Hawkeye fairway woods combine super light, super strong titanium and super heavy, super dense tungsten.
The new Callaway Great Big Bertha Hawkeye Titanium fairway woods are long off the tee, long off the fairway and long out of the rough, so even if you hit a wild one into the rough from the tee on a long par 5 you can pull out the Great Big Bertha and feel confident hitting it from the rough.
