BIG BERTHA ALPHA 815

LOW SPIN
WITH FORGIVENESS

BIG BERTHA ALPHA 815

The Big Bertha Alpha 815 is a new category of driver. We lowered the center of gravity, increased MOI and found more ball speed with a breakthrough R•MOTO Face and multi-material construction. The revolutionary Gravity Core can push CG even lower, increasing forgiveness and optimizing ball speed at impact. The result is a low spinning, incredibly forgiving driver that goes a long way.

Callaway Talks: Big Bertha Alpha 815 Introduction and Overview

What is low spin with forgiveness? It’s a compromise breaker, and Doctor Alan Hocknell and Evan Gibbs from Research and Development stopped by the studio to give us the details. Watch as they talk about the new R•MOTO face technology and how the club’s construction allows for lower spin but still allows for forgiveness and ultimately longer drives.

MAXIMUM DISTANCE

Lower spin from a forged composite crown, R•MOTO face and Gravity Core.
