Callaway Big Bertha (2006) (Irons)
Callaway | Irons | Add A Review
Our best game improvement irons keep getting better. Callaway Golf Engineers combined Extreme Notch Weighting and the Deeper 360-degree Undercut Channel to increase the Moment of Inertia by a substantial 8 percent. That means increased stability and reduced distance loss on off-centre hits.
Callaway Golf designers used Extreme Notch Weighting to reposition even more clubhead mass away from the centre and toward the heel and toe areas, so you get greater stability and forgiveness along with less distance loss on off-centre hits.
Shaft design features steps that are more shallow-angled than traditional steps, providing more efficient energy transfer. That, combined with the lower kick point, results in shots that get up in the air faster and with less effort.
The Constant-Width Sole is designed to help each iron in the set move smoothly and easily through the turf while also reducing catching or digging on missed shots.
By pulling weight even further away from the clubface using the Deeper 360-Degree Undercut Channel, the Moment of Inertia has been raised. That makes the club more stable on off-centre hits, so your shots go straighter and longer.
