The Callaway Big Bertha OS range is the ultimate forgiveness and distance package. It will largely be targeted at the higher handicapper and golfers who require assistance with launch.
The Exo-Cage makes the body of the iron more durable, which allows the weight to be placed in a more effective position within the iron head. This also allows for the 360 Face-Cup Technology to be installed. The Face-Cup innovation has increased ball speeds in Callaway products for the last few years and continues to boost ball speeds from all strike locations on the club face for added forgiveness.
Overall, these changes have repositioned the CG location in the longer irons to a lower part of the head to assist launch. The shorter irons however, do not feature any launch aids. As the OS irons feature a progressive CG location through the iron set.
“Most higher handicappers can still handle the short irons quite well. Super game-improvement irons are not a definition of the entire bag any more”
- Exo-Cage Technology – Allows for the weight to be repositioned
- 360 Face Cup Technology – Creates a hotter club face for increased ball speeds across the face.
- Progressive CG locations – Specific CG locations throughout the set to improve launch and spin.
