Callaway Big Bertha Alpha 816 DBD Driver: What you need to know
Callaway’s Big Bertha Alpha 816 Double Black Diamond Driver ($499.99) is available in lofts of 9 and 10.5 degrees for right-handed and left-handed golfers. Stock length is 45.5 inches. Stock swing weight is D4. It’s in stores Sept. 18, 2015.
Stock Shafts: Aldila Rogue I/O 60 (60-gram range), Mitsubishi Rayon Diamana D+ 70 (70-gram range)
What you need to know
- Callaway’s Big Bertha Alpha 816 Double Black Diamond is the lowest-spinning driver in the company’s new driver line. It’s as forgiving as last year’s Big Bertha Alpha 815 driver, and more forgiving than its predecessor, the Big Bertha Alpha 815 Alpha Double Black Diamond driver, offering a 45 percent larger sweet spot and a 30 percent tighter dispersion.
- The Big Bertha Alpha 816 Double Black Diamond, or DBD, has two “Distance Chambers” in the center of the sole — one closer to the heel, one closer to the toe — that allow golfers to vary the position of the driver’s Gravity Core for more draw bias (heel position) or more fade bias (toe position). Because of the Gravity Core’s design (read on), this creates four distinct CG positions: high toe, low toe, high heel, low heel.
- The Gravity Core, a stick-shaped object made of carbon fiber and tungsten, has a heavy end and a light end. In the past, Callaway advised golfers who needed a higher-spinning ball flight to position the Gravity Core heavy-side up in the club head, while golfers who required a lower-spinning ball flight were told to position the Gravity Core heavy-side down. This is still true with the new design, but…
“WE’RE SHIFTING THE FOCUS OF HOW WE’RE FITTING THE ALPHA DRIVER TO BE MORE ABOUT BALL SPEED AND LESS ABOUT SPIN RATE,” SAID EVAN GIBBS, CALLAWAY’S MANAGER OF PRODUCT PERFORMANCE.
- The spin rate difference between the Gravity-Core-up and Gravity-Core-down positions with the Big Bertha Alpha 816 Double Black Diamond driver has been reduced from about 300 rpm in previous versions to 200 rpm because of the Gravity Core’s shorter design.
- Callaway advises that golfers position the Gravity Core in the heavy-side-up orientation if they tend to contact their drives high on the club face, and in the heavy-side-down orientation if they tend to contact their drives in the middle or the bottom of the club face. Doing so moves the center of gravity (CG) more in line with impact area, which enhances ball speed. Callaway testing showed that 40 percent of golfers create more ball speed with the Gravity Core in the up position.

The DBD is all business at address with a matte black crown, no alignment aids and a slightly opened face angle.
“RATHER THAN DEMONSTRATE HOW MUCH WE CAN CHANGE SPIN AS WE DID WITH OUR PAST ALPHA DRIVERS, WE WANTED TO CREATE TWO TRAJECTORIES THAT ARE DESIRABLE TO TOUR PLAYERS,” GIBBS SAID.”BASED ON FEEDBACK AND TESTING, 200 RPM WAS THE SWEET SPOT.”
- The dual Gravity Core ports were made possible by the elimination of Callaway’s previous adjustable weight ports, which were used on the Big Bertha Alpha (2014) and Big Bertha Alpha 815 (2015) drivers to give golfers the ability to fine tune draw and fade bias. Their removal created the discretionary weight possible for the new design.
- Like the Great Big Bertha driver, the Big Bertha Alpha 816 DBD has a Forged Composite Crown, a structure that helps move weight lower in the club head. It also uses the same Advanced OptiFit Hosel, which gives golfers a 3-degree range of loft adjustability. So a 9-degree driver can be adjusted to lofts of 8 degrees, 10 degrees and 11 degrees. Each loft can also paired with an individual lie angle of either standard (S) or draw (D), which makes the lie angle more upright.
- The total weight of the Big Bertha Alpha DBD is 327 grams with Aldila’s Rogue I/O 60 shaft, which uses Aldila’s R.I.P. (Reverse Interlaminar Placement) Technology to give the shaft less torque, increased tip stability and a tighter feel.

Slab city on the Korn Ferry Tour — Lead Tape Report
This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.
Joel Thelen
Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.
First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.





Mitchell Meissner
Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

- macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”

Just picked up a 816 DBD in a X- FLEX to replace my X-Hot driver. The increase in distance was easy to see with lower spin and I was getting a tighter dispersion. Love it, I tested the great big bertha and it was nice, but nothing like the 816 DBD. I would play my X-Hot over the Great Big Bertha personally. Easy switch.

All you guys are right but only for the average golfer. Ya if your an average golfer you can’t really tell between this club and a 10 year older model. But when your a good golfer and hit consistently you can tell a huge different. Like it’s now known that about a 3% up swing on the ball give the best result and the golfers who are really good know that and can do it to get the most of of there drives. And sense that’s known now companies are making it so these new drivers can maximize that. Especially for a drivers like this and the other “pro” drivers companies put out.
You guys are dissing companies like taylormade and callaway for trying new things and saying that it doesn’t work. Well look how much father tour players are hitting the ball now compared to 5 years ago. It’s a huge increase! So the best advice I can give is to invest in a certified instructor who has the correct equipment to get you hitting the ball exactly how it needs to be hit and then you take advantage of the equipment coming out.
Also you guys really need to be fitted for the driver sense there all crazy adjustable now. You can loose a lot of yards and miss a lot of fairways if you have it tuned wrong or the wrong shaft and shaft length.
I have hit this driver and I was able to play a couple rounds with it before the release date and it is something special I absolutly loved it. I’m just a broke college student and $500 is crazy money to me. Clubs are becoming way over priced. But the day it becomes $400 this driver will be mine.
And KK it’s 200 rpms for both.

Zach says that Callaway is telling him Sept 18th release dat. My Callaway rep was in store yesterday and said firmly and without pause that the lineup will be in stores by the end of August. He also repeated that eh new Apex line will make an appearance just after Halloween.

not doubting zach, just curious what the actual scoop is.

Why release the driver that time of year? When the golfing season is ending, football starting. Buy the driver and store it for 6 months?
KK
Aug 5, 2015 at 10:50 pm
Is it 200 rpms per gravity core or 200 rpms for both? I love the look of the new DBD and the wide, tall face. Not a fan of composite drivers, though.

Hit this today and it is a very nice upgrade from the 815. More forgiveness with the deeper face and moving the gravity core makes a nice difference. Should be a popular choice for fitters.

All this is is a race of who can market the most BS for people to buy into. I agree this continues to be out of hand. Next thing they’ll resort to is nano tech paint jobs and whatever else they hope sticks to the walls when they throw it on deep. Try a better shaft and swing, until then.

All I need to know is that if I wait three months, the price will reduce $50; if wait 6 months, $100 off; one year, it gives a $150 discount. And probably one or two new models will come out and say: 400 RPM less spin with 40% more forgiveness. Even my kid will do a good math to add the spin reductions and forgiveness improvements claimed in the past a few year to find out: now everyone is having a negative spin rate driver with double /triple amount of forgiveness.

Does anyone else feel all this stuff has just gone too far? The entire illusion of small tweaks equaling significant game improvement just doesn’t hold much water. The bottom line is that if you swing poorly you get a poor result, if you swing well you get a good result. The return of small differences from all this tech is diminishing at best. If you doubt this grab a driver from about 10 years ago and try it against your current gamer. You will probably be surprised that the results are not as different as you might think they would be. It’s time for club manufacturer’s to stop the madness!

I view golf equipment like cars….is there really a difference between a 65 and 66 mustang? Not really….but premium options like fuel injection eventually trickled down making a 2016 mustang substantially better than a 1966…
While yes, each year (or decade for that matter) may not see discernible improvements there is no arguing that the technologies which last are richly importing the overall driving experience….pun intended
That’s all this is….trickle down technology that in the long run will make golf equipment incredibly more efficient and effective although year to year the improvements are almost imperceptible..

So buy a new driver every twenty years or so.
BTW I think a 60’s mustang would be a much better driving experience and much more desired car.
Christosterone
Aug 5, 2015 at 9:58 am
Sounds about right….personally, I would take a 60s E type jaguar over anything save maybe a 63 split window vette…
But to your point, yes and no…
Adjustability and 430-460cc head sizes are the fuel injections of today IMHO…
Loft, lie and face angle adjustments on drivers were reserved to pros and those who had access to club fitters prior to the str8 fit era….
We will eventually see adjustability in every club in our bag once the tech allows it…putters are beginning the conversion as we speak…
Club makers will continue to throw ideas at the wall seeing what sticks…ideas like square heads and mini drivers will come and go….but ideas that work will, like disc brakes, change our golfing lives for the better…

The problem with your theory is that a 40 year old car and a brand new car will take you from point A to point B. Both will go at above speed limit speeds. Golf drivers have speed limits. Take a 975d and any new driver to a golf course. And you will be surprised both will take you from point a to point b. I think it is more like computers or cell phones. They having these selling points that 99% of people will never use or need
Christosterone
Aug 6, 2015 at 8:27 pm
Computers are absolutely a perfect analogy…
I was simply trying to convey the fact that, like computers and cars, most year to year “advancements” are not discernible…but decade advances are more perceptible and tangible…
As said, I think your PC analogy is spot on!
