Cleveland Launcher Irons offer the highest MOI (Moment of Inertia) and the lowest and deepest centre-of-gravity available in any other Cleveland Golf iron. The Launcher Irons offer mid to high handicap players more accuracy and less loss of distance on off-centre shots, while their wider sole helps players get the ball up in the air quickly and easily. Made from 17-4 stainless steel and available in a high polish finish, the Launcher Iron?s extra large cavity and face help create an even larger sweet spot which will make the game more enjoyable for players of any level.
