The History of Callaway Big Bertha Golf Clubs

The two elements the original driver had in common with the howitzer was massive size--its head was 190 cc--and stainless steel construction. Both were radical departures from smaller persimmon drivers.

Besides setting a new standard for size and materials, the Big Bertha driver was revolutionary in that it put more weight around the clubhead's perimeter resulting in a thinner, more forgiving clubface.

Big Bertha irons were introduced in 1994. Similar to the driver, the clubs' oversized clubfaces and large, highly forgiving sweet spots targeted high-handicap golfers.

As the club design changed, so did the club names. From Big, Bigger and Biggest Big Bertha to Diablo drivers, the Big Bertha technology continues to evolve in 2009.

Although the Big Bertha line was designed to help high handicappers play better, touring pros have also benefited. Phil Mickelson, Ernie Els, Rocco Mediate and Gary Player all use Callaway equipment in 2009.
