Callaway X-18 Single Irons

The Callaway X-18 Iron has the "Extreme Notch Weighting" technology that is found in earlier X-series irons but it's optimized and has a sleeker appearance in the 18 model. The feature involves the placement of additional weight around the perimeter of the clubhead, particularly in the toe and heel areas. This design helps to increase the moment of inertia (MOI), enhancing stability and forgiveness on off-center hits. The Extreme Notch Weighting allows for a lower center of gravity, promoting a higher launch angle and more consistent distance control. This technology allows golfers to achieve more reliable performance on the course by stabilizing the club during impact.
