Tour Authentic Big Bertha Diablo Drivers

A driver that performs like no other all-titanium driver we've ever created, combining aggressive styling with wicked power. The unique clubhead shaping comes from Edge Technology, which provides a higher MOI and an optimized CG location to generate incredible distance with strong, penetrating trajectories. Edge Technology also helps golfers release the club at impact for maximum power. Cutting-edge Hyperbolic Face Technology increases ball speed across the entire face, even on miss-hits. And to be truly Tour Authentic, the Tour hosel creates the look and open face appearance that highly skilled golfers prefer in their driver.

• Hyperbolic Face Technology: Hyperbolic shaping is the cutting edge of driver face design. Mathematics and engineering combine to create Callaway's highest ever ball speeds across the entire face.
• Edge Technology: The unique shaping of the all-titanium clubheads allowed the engineers to move weight in specific locations to achieve the optimal CG location for strong trajectories with a higher MOI. It also helps close the clubface at impact so golfers can better release the club with power.
• Tour Hosel: A full-length hosel is placed closer to the face for less face progression and a more open appearance at address, which is the look preferred by highly skilled players.
