C523 HYBRID A new sole rail design on all C523 metals that extends from leading edge to trailing edge. The new sole rail design produces a super-low CG for high-launching shots with optimized spin rates, decreased turf interaction and maximum ball speed off the face. The rail design lowered the CG and allowed for a 36% increase in hitting area on the face of the fairway, making it easier to achieve greater power and increased forgiveness. A back weight is strategically placed to the extreme rear of the clubhead that places more mass at the extreme trailing edge of the clubhead. The back weight creates an extremely high MOI rating, an 11% increase over the previous iteration, for top in-line stability. This weighting dramatically affects a lower and deeper CG positioning of the club for ease of launch and more forgiveness off the face at impact. The Power Channel on the sole of the club behind the club face is strategically deeper and wider in the C523 design. The 90% larger Power Channel featured on the C523 Hybrid distributes weight to promote increased face flexing, amplified ball speed and less spin, as well as added forgiveness on shots struck lower on the face. Diamond Face Variable Face Thickness technology is a breakthrough in face technology that features 39 different thick and thin diamond shapes or “mini-trampolines” behind the face. Diamond Face VFT produces a hotter face with faster ball speeds and better performance on off-center hits, as well as reduced spin. The more compact profile and deeper face of the C523 Hybrid were designed with the competitive player in mind. The C523 Hybrid design sits open and has a more pear-shaped traditional design that player’s look for at address. This versatile hybrid will play from the tee, fairway, rough and around the green. C523 IRONS High-grade TPU VIBRCOR Technology strategically placed in the deep undercut pocket to create a new speed-inducing and feel-enhancing internal technology. VIBRCOR creates a distinct feel of the clubhead at impact that dampens sound and shock, while also creating perimeter weighting around the entire clubhead for maximum forgiveness and power and ball speed enhancement off the face. Features a more compact design, a thinner topline and a sharper high toe that promotes myriad game-improvement benefits in a classic iron. The more compact design of the C523 Iron has removed weight from the top line to create an ultra-low CG. The ultra-low CG placement promotes a high launch, stability at impact and added forgiveness on off-center hits. A wide sole of the C523 Iron and its deep 360-degree undercut cavity is optimized for playability, turf interaction and ease of launch. Offers superior bounce and increases launch for cleaner, high-flying shots and leads to cleaner turf interaction for more consistent shot making The 360° undercut cavity creates more face flexing and faster ball speed across the entire face. Advanced toe weighting has been strategically increased and made more visible in the new C523 Iron design. This added toe weighting maximizes stability on impact and provides better off-center hit distance from the face of the iron and elongates the sweet spot and creates a pure feel off the face of the irons. The lower and deeper CG allowed the C523 irons to be power lofted to create an extreme distance iron. Power lofting in this forgiving iron design promotes both distance & optimized height that achieves maximum distance without sacrificing the peak apex trajectory.
