From the Tour to the amateur golfer, distance with consistency is the ultimate performance goal. With M4 driver, we have combined our revolutionary Twist Face technology with a new Hammerhead slot and a refined Geocoustic sole design to produce straight distance with a massive sweet spot. The result is consistent driving performance through a premium blend of power, forgiveness, and accuracy.New face curvature w/corrective face angle on off-center hits, to reduce side spin & deliver straighter shots. Provides more loft in high-toe & less loft in low-heel for more consistent spin
Hammerhead slot: the reinforced outer portions of the slot allow for a lighter, more flexible face, resulting in a larger sweet spot
The center portion of the slot increases ball speed low on the face and drops unwanted spin for more distance
GEOCOUSTIC: Shaped for a solid and explosive sound. Reduced sole volume enables a larger, more forgiving face.
