Big, bad and bold are just some of the words to describe this powerful new iron design. The precision cast 431 stainless steel outer shell creates the foundation by placing additional mass directly behind the sweet spot optimizing the center of gravity deep and well back of the club face. This creates an extremely high moment of inertia (resistance to twisting) resulting in superior accuracy and an ideal driving trajectory. It is joined with a separate high-performance face plate formed by an ultra-thin sheet of high strength 420 specialty maraging steel, which translates into a more explosive ball velocity off the club face for the ultimate in distance. From the ultra-wide beveled sole and heavy rear mass to the unique appearance at address, the Caiman Irons put more raw power in your hands to produce shots that you've previously only dreamed of..
