The Big Bertha Fusion driver has forgiveness as its focus, developing a clubhead design built around an aerospace-grade titanium exoskeleton called an Exo-Cage that is fitted with a crown and sole composed of an light, strong material called triaxial carbon.
The new triaxial carbon material is said to be over 65 per cent lighter than titanium based on material density, and more than 35 per cent thinner than Callaway’s previous forged composite material.
This allows Callaway to position 35.4 grams in strategic areas of the head to optimize the centre of gravity and increase MOI by up to 17 per cent compared to the XR16.
This driver also incorporates Callaway’s Speed Step technology, devised with the help of aerospace experts, to enhance the head aerodynamics, promoting faster clubhead speeds.
Big Bertha Fusion comes stock in both a 45.5 or a 44.5-inch length. All stock configurations are available with UST’s new Recoil driver shaft that’s designed to load more efficiently on the downswing and unload with greater power and precision through impact.
The other option is Mitsubishi’s Diamana Red shaft that combines a firm midsection and active tip to promote high launch, low spin and fast ball speed.
Big Bertha Fusion Fairways
The crown is composed of a light, strong triaxial carbon material and weighs in at just 5.8 grams, 78 per cent lighter than a typical steel crown, allowing Callaway to position weight in strategic areas of the head to enhance centre of gravity and increase MOI.
The Hyper Speed Face Cup is used to promote higher ball speeds all across the face, leading to more distance.
The fairways are also available in stock 44.5 and 45.5-inch lengths.
