Callaway Big Bertha Alpha 816 Double Black Diamond driver review

Key technology
Aimed predominantly at better players, the deep-faced Big Bertha Alpha 816 Double Black Diamond driver now features Dual Distance Chambers located in the heel and toe, one of which houses the Gravity Core.

As such, golfers can now alter both shot shape and spin. Next-generation R-MOTO Technology provides the structure needed for a thinner face, leading to faster ball speeds
on both centre and off-centre hits. A slightly open face angle and matte-black finish should also suit the eye of better players at address.

Shaft options
14 shafts are available with no upcharge. The stock models are the Aldila Rogue I/O 60 and Mitsubishi Diamana D+ 70.

Loft options
9° and 10.5° (adjustable)

Will suit
Better players looking to control their dispersion while keeping spin levels low.

GM verdict

The deep face, combined with the shallow head length from front to back, leaves you in no doubt that this driver is aimed at the better player who likes to work the ball. The crown aesthetics are clean and simple, with a matte- black finish preventing any glare from the sun.

During testing, placing the Gravity Core in either the heel or toe Distance Chamber to align with lateral mishits proved to be an effective way to achieve a solid feel and more ball speed, provided you can manage the shot shape from the sweet spot in this setting.

Combined with the extra eight settings available on the adjustable hosel, this creates a forgiving driver that good players should be able to use to find a setting that maximises both distance and accuracy. The feel from the sweet spot is incredibly solid, while the low-spin flight optimises both carry and roll out.



A premium looking driver with a shape and size that will suit the eye of the better player that likes to shape the ball. The feel off the face is incredibly hot and stable and there's a surprising amount of forgiveness on offer, helped by the plethora of adjustable settings that can be used to negate bad shot tendencies.
