The Callaway Big Bertha Fusion Driver is all about hitting fairways over and over again. The technologies that Callaway have been able to use in this revolutionary head shape has allowed them to call the Fusion Driver their most forgiving ever.

Callaway have used a fusion of Exo-Cage titanium and Triaxial Carbon to develop a crown and sole technology that saves incredible amounts of weight and allows them to reposition it to areas of the club that will benefit you whatever your handicap.

By repositioning the weight saved in the crown and sole design to the furthest, deepest point of the head Callaway have been able to dramatically increase the head's MOI. This in turn raises forgiveness through the roof so that off-centre hits travel as far and as straight as those good ones.

To encourage faster clubhead speeds Callaway have used their Speed Step Crown technology, co-designed with Boeing, to reduce air drag over the head. This is what will give you that extra MPH!

To maximise this weight saving and extra MPH on your swing, the face features the excellent R:MOTO face technology. R:MOTO extends the size of the hitting area to increase forgiveness as well as produce incredible levels of ball speeds across the whole face.

Callaway have used the super premium UST Recoil shaft as their stock shaft. The profile of this shaft will allow the shaft to load more efficiently on the downswing and release greater power through impact for faster ball speeds.

Innovative Exo-Cage For Forgiveness & Power

Titanium Exo-Cage makes it possible to reposition weight for more forgiveness and increased swing speed to increase accuracy and distance.

Fusion Technology For Maximum Forgiveness
Fuses a titanium Exo-Cage with an ultralight triaxial carbon crown and sole to create forgiveness and stability, promoting straighter and longer drives.

Industry-leading Aerodynamics For More Head Speed & Distance

Callaway's proprietary SpeedStep, designed with help from aerospace experts, reduces drag to promote faster swing speed for more distance.

“Big Bertha Fusion’s innovative construction, which combines a titanium Exo-Cage with a Triaxial Carbon crown and sole, wouldn’t be possible without the nearly 20 years we’ve spent researching and developing carbon fiber technology.”
-- Dr. Alan Hocknell Senior Vice President, R&D

“Big Bertha Fusion’s unparalleled forgiveness and stability at impact promotes straight flight on mis-hits and gives golfers the green light to make a fast, aggressive swing.”

-- Evan Gibbs Director, R&D - Woods
