BIG BERTHA ALPHA 815 DOUBLE BLACK DIAMOND

Big Bertha Double Black Diamond is the perfect choice if you need ultra low spin to maximize your distance. It’s made for players that generate high ball speeds and hit the ball in the center of the face a majority of the time.

The face is lighter from R•MOTO technology, and we use that leftover weight to move the center of gravity low to reduce spin. In the Double Black Diamond, we’ve also added a taller Gravity Core so you can finely tune your spin and launch conditions in a compact head shape with a deep face.
