Mizuno’s player’s driver combines the scope to optimize launch and spin with the ball speed enhancements of Mizuno’s CORTECH Chamber. Beta Rich Ti LFS Face: A new lighter, faster face material! Measuring 9% higher in tensile strength (compared to SAT2041) for a complex multi-thickness face geometry. Tour testing demonstrated an average 1.5 mph ball speed increase compared to SAT2041. CORTECH Chamber: THE MISSING PIECE: Mizuno's CORTECH Chamber encases a dense stainless steel weight with elastomeric TPU, taking stress from the club face and creating an additional energy source. At the same time, locating weight closer to the club face to reduce spin rates, while contributing to a more solid, powerful sensation at impact. Max Convergent Fast Track: Mizuno's weight track system that allows for optimizing launch conditions. Two weights can be pushed to more extreme positions for ultra-low spin to mid-low spin settings. Compact 440cc Players Profile: An inviting modern pear shape that sits perfectly square in the neutral setting. Ultra-lightweight Carbon Crown: Ultra lightweight carbon allows weight to be moved low within the clubhead. Expanded Carbon Crown: An extension of lightweight carbon into the toe section allows an even greater level of shot shaping ability. Quick Switch Adaptor : 4 degrees of loft adjustability to fine tune trajectory and look. Harmonic Impact Technology: Fine tuned head geometry delivers ideal impact feel and feedback
