Release your inner Diablo with the Callaway Big Bertha Diablo driver, an all-titanium club that delivers wicked power and distance to go along with a generous sweet spot. The Big Bertha Diablo incorporates Callaway's Edge Technology to create a high moment of inertia (MOI) and an optimized center of gravity (CG) location, giving you a long, penetrating ball flight and any shot shape that you desire. The club also offers Hyperbolic Face Technology, which increases ball speed across the entire face for more distance on both regular shots and mis-hits. The club even helps golfers square the clubface at impact--a terrific advantage when swinging aggressively. As a result, the Big Bertha Diablo performs like no other all-titanium Callaway driver. As the company says, long is good, but longer is better, so go ahead and knock the hell out of it.
