A.I. Flash Face Cup
For the first time in a Big Bertha iron, Callaway Golf has introduced the same technology used in their new drivers to achieve more performance. Flash Face was created using artificial intelligence to provide increased ball speed off the clubface. This is incorporated into the iron design with industry-leading 360 Face Cup which flexes and releases at ball impact for even more distance performance.
Visible Tungsten Energy Core
Callaway Golf has precisely infused a visible Tungsten Energy Core (VTECH) into each iron to optimize launch and trajectory. This deepens the CG to optimise launch while still maintaining ball speed in the face.
Proprietary urethane microspheres offer a beautiful feel. Over a million patented microspheres are strategically placed into each clubhead to absorb unwanted vibration at impact. This premium technology also maximises COR, so as well as providing a pure feel, you also get consistent performance.
