Using Fusion Techonology
The goal in using Fusion Technology is not only to better overall performance, but to also make the golf clubs like ping g15 irons give optimum performance when hit off-center (with irons and woods). Using this technology helps the ball have maximum flight and distance, even when it's not hit directly in the middle of the clubface. Ishiner This is mostly due to Callaway's design feature offering minimal clubhead movement when impact occurs.
