The Hammerhead Slot
A new sole slot design, the Hammerhead Slot was engineered specifically for high ball speeds and forgiveness, extending the effective hitting area across a larger portion of the face than the Speed Pocket designs that preceded it.
Geocoustic, Refined
The M4 carried forward the Geocoustic approach first introduced on the M2, optimizing both crown geometry and sound simultaneously, so the driver looked, sounded, and performed as one coherent design rather than separate engineering afterthoughts.
Look, Sound and Feel

A harmonious blend of power and precision, a satisfying, distinctive, confidence-inspiring sound that resonated with a wide range of golfers.
Look
Clean lines and a balanced visual composition, with a matte black crown that reduced glare and aided alignment for a striking, modern look.
