Callaway Men's Big Bertha 816 Double Black Diamond Driver

The new Big Bertha Alpha 816 Double Black Diamond Driver is built for the best players, the studs, the big bombers, the ones who stripe it off the tee like clockwork. They're already long and they'll get even longer with the new Dual Distance Chambers that give them exactly what they need to get every last yard out of their drives.

You can use the Gravity Core as a distance turbo charger for more ball speed, and it's easy to do. Just pick your Distance Chamber for a draw or neutral setting. Then flip the Gravity Core up or down depending on where your normal impact location is on the face. Set the gravity core up for impact locations above center, or down for impact locations at center or below. You do that, and you'll get the ball flight that you want to play, with maximized ball speed set to your impact location. Throw in a faster, deeper face and our OptiFit adjustability and you can see why this club deserves to carry the Alpha name. It's the ultimate combination of distance and shot-shaping control for the highest caliber players.
