Technology / Specs

The Big Bertha Alpha 815 driver should and will find its way into most golfers’ bags. Callaway managed to lower spin and increase forgiveness, and this combination is achieved through multi-material construction, RMOTO face technology, and multiple adjustment capabilities including the Gravity Core.
The Big Bertha Alpha 815 driver’s multi-materials include a forged composite crown and lighter titanium for the face of the club. The combination of these materials creates a low center of gravity (CG) with maximum forgiveness while increasing ball speeds on the face.
The RMOTO technology saves weight in the club to move the CG lower in the design. This CG shift increases the moment of inertia (MOI) to efficiently transfer energy back to the golf ball at impact increasing ball speeds for more distance.
The Big Bertha Alpha 815 driver includes full adjustability by incremental movements made with the Gravity Core, OptiFit hosel, and interchangeable weights. The Gravity Core is a patented weight designed to vertically adjust the CG. By moving the CG you can optimize ball speeds determined from your impact positions. The OptiFit hosel allows you to select one of eight different loft and lie angles to fine tune the trajectory. The adjustable one and seven gram weights in the toe and heel of the golf club allow you to dial in the shot shape of the driver.
The Big Bertha Alpha 815 driver is available in 8 and 10.5 degrees and comes equipped with a Fujikura Speeder Motore 565 shaft. However, there are multiple custom options available.
