The Callaway Big Bertha 06 irons are the latest in the Big Bertha iron product line renowned for maximum forgiveness and playability and build on new technologies that deliver improved performance. The Big Bertha 06 Irons are available in 2-iron through Lob Wedge and come in a standard set configuration of 3-iron through Sand Wedge and are priced the same as the current model. They are for players who seek a solid, game-improvement iron combining forgiveness, performance and styling. Essential core technologies consisting of S2H2, Tru-Bore and Variable Face Thickness (VFT) and a constant-width sole, added with extreme Notch Weighting and a deeper 360-degree Undercut Channel result is a game-improvement iron bristling with technology. Extreme Notch Weighting allows Callaway Golf club designers to move mass to the perimeter of the clubhead, mainly to the heel and toe, for increased forgiveness and distance on off-center hits. The deeper 360-degree Undercut Channel further maximises the benefits of perimeter weighting by enhancing the clubhead’s stability and resistance to twisting. All Big Bertha 06 Irons come with a polished-chrome finish with red and black accents.
