The Callaway Big Bertha Irons feature Callaway's new Suspended Energy Core. This revolutionary new construction suspends the Tungsten weight using Callaway's proprietary urethane microspheres. The result is an easy launch; long consistent distance; and incredible sound and feel.
The New Big Bertha's utilize Callaway's innovate 360 Face Cup technology, which employs a flexible rim around the face that releases at impact to generate unreal ball speeds. The high launch angles generated by the Suspended Energy Core allow Callaway to make this the thinnest face cup they've ever created, thus furthering ball speed and distance.
The Big Bertha's have a clean, attractive smoked PVD finish. The Bertha's are available with UST's Recoil ESX and Recoil ZT9 in graphite, while the KBS Max 90 is the steel shaft offering.
