Callaway Great Big Bertha metalwoods unveiled

The new Callaway Great Big Bertha metalwoods are designed to help all levels of golfer achieve more distance thanks to a breakthrough in clubhead construction

Watch the above video to see our review of the new Callaway Great Big Bertha driver.

Callaway’s first ever Big Bertha driver was launched in 1991 and represented a huge breakthrough in golf club technology and the latest model to bear this iconic name is no exception.

The new Callaway Great Big Bertha driver, one of two new drivers along with the Callaway Big Bertha Alpha 816 Double Black Diamond, is an adjustable driver with a light, fast and stable chassis that Callaway say represents a technological breakthrough that will get the most distance for all levels of golfer.

Callaway achieved this by optimising the multi-material chassis to generate more clubhead speed through aerodynamics and a wide range of weight classes to suit every swing type, from 295g to 325g, thanks to the 12 stock shaft options.

The next generation of Callaway’s R-MOTO technology also provides the structure for a thinner face, which leads to faster ball speeds on different strike points across the face.

Finally, Callaway have added the Adjustable Perimeter Weighting we saw on the 2013 Big Bertha driver, that uses a 10g sliding weight for ball flight and dispersion control while maintaining forgiveness. The Optifit hosel also lets you choose from eight different configurations to tune loft, lie, and face angle.

The Great Big Bertha fairway wood also returns and is Callaway’s fastest fairway wood to date thanks to the latest incarnation of the brand’s Forged Hyper Speed Face Cup technology offering distance, forgiveness and control. The ball speeds are higher on centre and off-centre hits than previous Callaway fairway woods.

A bigger head than a typical Callaway fairway wood increases forgiveness further while the Modern Warbird Soleplate makes it easy to hit from a variety of lies with a mid-launching trajectory. The eight-way adjustable hosel allows you to tweak the loft or lie angle to fit your swing.

The Great Big Bertha fairway wood also comes in a special Heavenwood (20.5°, 43-inch shaft) and Divine Nine (24°, 42-inch shaft) to help your gapping.

The Great Big Bertha driver has an RRP of £369 while the fairway wood RRP is £229. Both will be available in stores on September 18th.

How has the Callaway Great Big Bertha driver improved? The new Great Big Bertha has a similarly high MOI to the 2013 Big Bertha driver with Adjustable Perimeter Weighting, but has been upgraded to feature a lower Centre of Gravity, more draw shape capability and the addition of Callaway’s R-Moto face technology.

The head itself is 3g lighter than the 2013 Big Bertha APW thanks to a totally re-engineered interior, a lighter weight track than in the APW plus an R-Moto face (which has been improved further Vs the 815 version).

The stock shaft offerings are significantly lighter than what was previously available with APW by 21g and 9g with the Bassura and Kurokage shafts respectively.

Great Big Bertha 2015 v Big Bertha 815 The new Great Big Bertha has been designed to give all of the performance benefits of the 815 but with even more forgiveness to broaden its appeal to all golfers, including:

• Much higher MOI than the standard 815
• A slightly higher CG
• More draw bias capability
• A significantly lighter set up. While the headweight of the Great Big Bertha is 7g lighter than the standard 815, with further overall weight savings via the new stock shafts.
