Building on the combination of distance and forgiveness of the 2014 and 2016 models, the Big Bertha 19 irons utilise a ‘Suspended Energy Core’. The core comprising of a ‘Metal Injection Moulded’ tungsten floating weight suspended within urethane microsphere material.

Suspending the weight allowed Callaway’s engineers to more precisely place the centre of gravity (CG) within the head, which uses a three-piece construction, meaning the 360 cup face employed in the previous Big Bertha irons could be made even thinner to deliver faster ball speeds. The combination of higher ball flights, with more speed producing increased distance, without negatively affecting forgiveness.

First appearing in the company’s Rogue iron range, the urethane microsphere material encasing the floating tungsten weight produces a pleasing feel of the clubface without affecting ball speed and COR unlike other materials used to dampen vibrations through the small microspheres flattening under pressure. This flattening creating room for the face to flex and return unhindered.

Released in conjunction with the new irons, the latest Big Bertha Hybrid incorporates a ‘Hyper Speed’ face cup with Callaway’s ‘Jailbreak’ technology and adjustability, to offer customised distance and forgiveness.

The Big Bertha 19 irons and hybrids will be available around Australia beginning Friday November 16.

RRP: $219.99 per iron (steel); $239.99 per iron (graphite); $419.99 (hybrid).
