If you already own the Callaway Big Bertha Fusion Driver please leave your review in the customer review box at the end of this article.

Callaway, and, more specifically Big Bertha, were one of the pioneers of the seismic changes in drivers in the 1990s. And getting that nose in front at the time has ensured that they’ve been at the forefront of the argument ever since.

At the heart of the trend the early Big Bertha ranges helped to set was forgiveness, and this is a mantle which the new Big Bertha Fusion Driver carries in spades. Of course, the original Callaway Fusion range of woods first saw the light of day back in 2004, but what’s happened since is that they’ve got lighter and lighter. And lighter.

We reviewed the Callaway Big Bertha Fusion as part of our best golf drivers roundup.

Our Assessment 

The Big Bertha Fusion driver marks a notable shift in direction and priority at a time when all the emphasis seems to be on adjustability. Forgiveness, at the end of the day, appeals to golfers of all abilities. Even the best need a hand at times. Distance-wise, we’d say it holds its own, without excelling in that category. But, on the whole, Callaway have taken innovation to another level, with a product made of high-quality materials and the pinnacle in technology. As such, we think this puppy will have a whole lot of appeal - and not just for newbies either.

  • Forgiveness, forgiveness, forgiveness. It doesn’t feel like you can miss a fairway!
  • The Exo Cage and cutting-edge triaxial carbon do an excellent job in tandem, with the MOI figures to prove it
  • Feels solid at impact, with market-leading stability throughout the swing
  • Still has all the adjustables you need in terms of loft and lie angle


  • You’ll have to dig deep into the pockets here. But then again, Boeing engineers helped design it!
  • Just perhaps lacks a bit of distance

Callaway Big Bertha Fusion Detailed Review

Build Quality

As mentioned above, underpinning the forgiveness factor of this club is the combination of the Exo-Cage and triaxial carbon. The carbon composite material is roughly a third less dense than titanium, and it meant that the designers effectively had another 35g to distribute across the clubhead.

The priority as such was to enhance the Moment of Inertia (MOI), which, in layman’s terms, measures the stability of the clubhead when the sweet-spot is handsomely missed, and, by extension, the amount of ball speed lost.

And this is where the weight saving as a result of the triaxial carbon comes in so handy, as, with the additional weight in the medallion and weight pads, the MOI soars around 17 per cent higher than that of the Callaway XR-16, which came out earlier in 2016.

But the improved MOI works handily in conjunction with the center of gravity too, which sits unusually low and deep in the club.

The near-triangular shape of the clubhead effectively paints the picture for you of what’s going on inside the clubhead, and it all results in unparalleled stability – and therefore forgiveness too.

Control & Performance

It’s all very well having a club that’s forgiving, and which makes your poor shots less poor. But what about the good ones? What can you do with the ball when clutching the Big Bertha Fusion in your palms? Actually quite a lot, in truth, and the key lies in the various shaft loft angles you can choose from.

The stock version of the driver comes with shafts of two lengths: namely 44.5 inch and 45.5 inch. They say the shorter option is likely to further enhance forgiveness, but for tall chaps like me the 45.5 inch version is a no-brainer.

But within that you’ve got a choice between UST’s new-edition Recoil shafts (which weigh between 45-55g), or the slightly heavier Diamana Red shaft (63g).

I found the Recoil shaft to be a bit whippy, but the point is that there is so much flexibility there that finding the right balance to optimise performance is as easy as sampling a few different varieties of a bunch of winning formulas.

In terms of loft, we think the 9.5 and 10.5 degree options will be the most popular, but you can even choose the 13.5 degree clubface and adjust it down by a degree or two. It really does have all options covered.

In summary, there is plenty of flexibility on offer, and it really does reflect in the output when it comes to power, shape, trajectory and accuracy. You can be the architect of your own success with this one.

Design & Appearance

I haven’t necessarily thought that Callaway drivers are the most beautiful out there – least of all the square monstrosities such as the FT-iQ. It’s purely subjective of course, but being a Taylormade man myself, we all have our preferences!

That said, the Big Bertha Fusion certainly isn’t an eyesore, and more importantly, it sits nicely on the deck. It’s pretty streamlined too, with the favored triangular shape. Somewhat different to its rounded predecessor, the Callaway Great Big Bertha Driver.

In terms of design, it’s fair to say that the face is wider than it is deep. There is the classic Callaway eight-way adjustable hosel, which, like the XR-16, means you can adjust loft without affecting the face-angle settings.

The so-called ‘Speed Step’ crown is another continuation of the XR-16 features, and is said to help with reducing aerodynamic drag.

I was reasonably satisfied with the distances I was getting, so that suggests it does the job.

Appearance may not be at the very top of the totem pole, but it’s important to look down when you address the ball and feel the part. So credit to Callaway here for upping their game and delivering something that just about passes the aesthetics test.

Value for Money

It’s a tricky one to form an opinion on in terms of value. But for me, the best way to look at it is to benchmark the Big Bertha Fusion against the XR-16. First in terms of attributes, and then price.

Are you getting considerably more in terms of features and quality?

To me, that’s a definite yes. Forgiveness goes through the roof, the levels of technology and quality of materials are at a whole new level, and, to top it all off, you’re getting something streamlined which actually looks the part.

All of this for an extra 50 bucks?

If you’re a Callaway man, and hitting fairways is your priority, then that seems like good value to me.

Mike fell in love with the game from a very early age – a passion that hasn’t diminished ever since. He earned provincial colors throughout his junior years, but by the time he reached Varsity, the realization set in (thanks largely to some cold ales) that it was time to favor the pen rather than his clubs. He now writes for GA along with a few other sources.

  1. Liked your article on the Callaway Fusion driver. Being 6’2 thought I’d be much better off with the 45.5″ shaft…Not even close…The 44.5″ shaft gave me more control and distance. You were spot on about forgiveness. This past season I’ve hit the fairways at a way higher percentage than anytime in my life. Also, off center hits traveling a lot farther and finding fairway. Couldn’t be happier! The last 4 times out I switched to a 44.5″ Oban shaft and gained 15 to 20 yards on avg..Spent a lot for the shaft and worth every penny! I was getting good distance with the 460 Mamiya Recoil, but glad I switched to the Oban. All in all, highly recommend the Fusion driver.
