Callaway Diablo Fairway

Callaway's Cutting-Edge Technologies

The Big Bertha Diablo's most notable innovation is the uniquely shaped all-stainless-steel clubhead, which allowed Callaway engineers to play with different weight locations when designing the club. The flexibility resulted in an optimal center of gravity (CG) for both the "draw" and "neutral" options, along with a higher moment of inertia (MOI). There's no better wood for golfers who want to overcome their natural swing flaws and hit the ball straight down the fairway. The design--dubbed Edge Technology--also helps close the clubface at impact so golfers can better release the club with power.

The Big Bertha Diablo also employs a couple of other classic Callaway designs: Variable Face Thickness (VFT) and S2H2. With VFT, Callaway built varying levels of face thickness into the club, resulting in an optimum ball speed from all areas of the clubface. Even if you don't hit the ball dead center, it's still possible to hit a monster drive. The S2H2 design, meanwhile, increases the club's discretionary weight by removing it from the hosel and repositioning it in the perimeter of the clubhead. Not only does this help with distance, but it also improves the feel and stability of the club. Add the features together and you have a club that's sure to please everyone from beginners to low handicappers.
