Callaway Big Bertha Alpha 815 Double Black Diamond Driver

Lighter Weight In The Face Leads To Low CG

Remember this name – R•MOTO. It’s the new face technology that provides structure and saves weight (leading to higher ball speeds all across the face), and we use that weight to move the CG low and more forward to give you even more speed.

Adjustable Launch Conditions

We modified the crown of the driver so we could fit a taller Gravity Core. This gives you more spin separation between low and high settings. All without changing loft or face angle.

Compact Head Shape

The players who use this kind of driver like a deeper face, and that’s what we’re giving them. The shape of the crown and face angle at address all suit better players’ eyes.

OptiFit Adjustability

8 way adjustability for loft and lie angle, along with Draw and Neutral CG settings.
