The M2 provides maximized distance and height, now with face slots for increased forgiveness. It's pushing the limits in iron design and engineering. The M2 has ultra-low CG & max-cor, wtih moving discretionary weight lower in the head via the new 6-sided fluted hosel and ultra-thin 1mm top line provides higher launch and incredible distance. Combined with a 1.5mm thin, max-cor face, M2 gives golfers consistency on each strike, face Slot technology that is engineered into M2 irons for the first time, face slots provide added forgiveness on shots struck toward the heel or toe. Complemented by speed pocket technology, which preserves distance on shots stuck low on the face, golfers experience ultimate forgiveness on every mis-hit. Geocoustic engineering, which is acoustic engineering thru geometry combined with a multi-material fin-badge, dampens unpleasant vibrations for confidence-inspiring sound and feel.
