The Big Bertha Alpha driver, as used by Phil Mickelson is already creating waves on tour and no surprise - it's the most technolocally advanced driver in Callaway's portfolio.
For the first time, the player can adjust spin independently of launch angle. The secret is the gravity core - simply whip it out and switch it around to move the weight from the crown which promotes a high centre of gravity for a lower launch to the bottom for a lower centre of gravity and a higher trajectory.
The double cog system offers adjustibility from 8 to 12 degrees loft and lie angle to draw or neutral. Moveable heel and toes weights (it comes with additional weights) complete the options. The shaft is the same one used on tour - The Fabuki Zeta Tour.

Gravity Control Adjustability
What’s the story on Gravity Control Adjustability? Let’s break it down:
- For the first time ever, the Gravity Core lets you adjust unwanted spin independently of launch angle, so you get completely optimized ball flights and longer distance. You want an extreme low spin driver? You can have it. Or a more total performance, mid-low spin driver? Yep, absolutely. It’s not magic; it’s the Gravity Core in action.
- Together with the adjustable hosel, players now have an added dimension of adjustability to optimize launch angle. So now you get EVEN MORE ball speed and distance. We hope that’s okay with you.
- Dial in your preferred directional bias with the adjustable weights, enhancing a Draw or Neutral shot shape for more accuracy. Whatever flight you want, Big Bertha Alpha can give it to you.
Hyper Speed Face
A revolutionary new face design – it’s larger, and more robust than ever to increase ball speeds across the face. Expect longer drives, more consistently.
Advanced Adjustable Hosel
Here’s the quick 3-step process. Step 1: Increase or decrease loft in 1° increments (up to +2° or down -1°) to optimize launch angle and spin. Step 2: Adjust Draw or Neutral bias to optimize shot shape. Step 3: Hit absolute bombs off the tee, maximizing distance with more accuracy. Players really seem to like step 3.

Forged Composite
It’s a high strength, lightweight crown that saves crucial weight. And here’s what we get by saving that weight: Adjustable Perimeter Weighting, a deeper CG for more forgiveness, and low spin with a lighter, more preferred swing weight. That’s why when you add four independent forms of adjustability to a driver for the first time ever, you’ve got to have Forged Composite.
