The Big Bertha family of drivers from Callaway Golf is getting so big that it's going to be tough to fit them all around the table at Thanksgiving. The Big Bertha and Big Bertha Alpha, both unveiled late last year, were recently joined by the V Series, and now come two more models – the Big Bertha Alpha 815 and the 815 Double Black Diamond.
The V Series is a lightweight driver for golfers who need help generating their maximum swing speed. The Alpha 815 blends both distance and forgiveness for a wide range of golfers (it's significantly more forgiving than the original BB Alpha), while the Double Black Diamond – as any snow skier knows – is for experts only.
The Alpha 815, Callaway says, represents a brand-new driver category: low spin for extra distance with the forgiveness many golfers need to hit the ball straight. The Double Black Diamond is an extremely low spin model for advanced golfers who don't need a lot of help hitting the ball down the middle of the fairway.
Both these new models feature the Gravity Core that Callaway pioneered in the original Big Bertha Alpha. One end of the core has a heavier weight while the other has a lighter weight; golfers can move the center of gravity up or down depending on which way they insert the Gravity Core to optimize their ball speed locations to wherever they usually hit the ball off the face.

The heads, larger on the 815, slightly more compact on the Double Black Diamond, what Callaway calls "RMOTO:" technology that lets the company produce a larger, more forgiving clubhead while maintaining a lighter overall club weight. It also has an ultra-thin face. Like many recent models, these heads are also made of strong, lightweight Forged Composite material.
Both drivers also feature Callaway's OptiFit adjustability. The adjustable hosel lets golfers choose from a combination of eight different loft and lie angle (Draw or Neutral) configurations, while heel and toe weights (1- and 7-gram weights for the 815, and 1- and 5-gram weights for the Double Black Diamond help dial in your shot shape even more.
These new models come with a 53-gram Fujikura Speeder Motore 565 shaft as their primary stock offering, but Callaway offers no-upcharge upgrades to a variety of premium shafts including models from Aldila, Fubuki, Fujikura, Matrix and Mitsubishi.
The Big Bertha Alpha 815 carries a suggested retail price of $449.99, while the Double Black Diamond goes for $499.99. Both will be available on Nov. 14.
