Callaway Big Bertha Alpha 815 Double Black Diamond Driver Review: ClubTest 2015

February 5, 2015

Callaway Big Bertha Alpha 815 Double Black Diamond Driver


Category: Better-Player Drivers
Price: $499
9° (adjusts 8° to 11°), 10.5° (adjusts 9.5° to 12.5°) with Aldila Rogue 60 graphite shaft
KEY TECHNOLOGIES: Moving more weight low and forward in the head reduces spin and increases ball speed.



DISTANCE: One of the highest-rated models in the category; about as long as any on solid strikes; carry distance is excellent, but it also produces better roll than most; they don’t call it Alpha for nothing—this thing is a beast!
ACCURACY/FORGIVENESS: Accurate and consistent from shot to shot, even on slight misses; a power driver that’s easy to hit; surprisingly good at correcting shots struck on the toe; a lot more forgiving than the compact-looking head would lead you to believe.
FEEL: The highest-rated model; impact is springy and powerful; a distinct difference between solid hits and misses tells you what you’ve done wrong; substantial, a weighty feel to the head throughout the swing.
PLAYABILITY: The highest-rated model in the category; a rare combination of shotmaking ability and distance; big-time versatility lets you hit the shot you need; “Gravity Core” adjustable CG design allows for variable ball flight and spin options on demand; slightly higher trajectory bores through the wind.
LOOK: The clear favorite; the compact, pear-shaped head reminds guys of old-school clubs; impressive quality all around; every aspect of it is high class.



Though surprisingly forgiving, it’s definitely not the friendliest model around; multiple adjustable technologies can be confusing to some testers.

BOTTOM LINE: One of the highest-rated models in the test. A top performer across the board—it’s long, extremely playable, handsome, and surprisingly forgiving.

HOT STIX’S TAKE: Geared to players looking for relatively low spin and launch. The “Gravity Core” shifts the CG higher/lower for more spin options. Two weights influence fade/draw bias.Launch – Low; Spin – Low

From the November 2014 Issue of Golf Magazine

The Alpha 815 has the same light, forged composite crown as before, along with a thinner, livelier titanium face that’s made possible by stiffened ribs on the crown and sole, inside the body. Also, removable plugs in the heel and toe (7 gram and 1 gram) can be used to create fade or draw bias. Like its predecessor, the Alpha 815’s adjustable OptiFit hosel provides loft options (from 2° stronger to 1° weaker), as well as neutral or draw settings. Lofts: 9°, 10.5°, 12°.

Its sibling, the Big Bertha Alpha 815 Double Black Diamond ($499), is geared at faster swingers who benefit from less spin. A taller gravity core alters spin by up to 400 rpm. Both models are available Nov. 14. — Michael Chwasky
