THE GOLDEN IMPACT
that formulates supremely strong trajectory

The PROTO-CONCEPT C01D features a thick, energy-efficient impact with proprietary technology from the world’s best production plant.

The forged cup face crafted from patented technology provides unprecedented feel and powerful line drives, stimulating the senses of golfers.

Yield trajectory as imagined

Clubs identify golfers. This is our proposition from PROTO-CONCEPT. What kinds of clubs golfers choose and put in their bags tell their playing styles.

The playing style the C01D proposes is ‘realistic’ golf. It hones the senses to hit the fairway with strong trajectory and ball flight like imagined. Its amazing feel and distance uplifts golfers and hits their next great shots.

The joys that only true drivers possess

The C01D is engineered with proprietary gravity design pursuing ease to capture the ball, swing and handle while possessing moment of inertia exceeding average drivers. This is a driver that delivers pleasure for each and every swing through its head performance that produces a more biting impact on the ball and a crisper finish.

Any driver delivers distance.
The C01D guides toward joys beyond that only golfers can experience.

Technology

The C01D is manufactured by a forging plant boasting the world’s best technology. The company had been reluctant to produce woods in recent years, but the C01D was born out of resonance with PROTO-CONCEPT’s idea of “incorporating all possible functions, materials, and techniques” in low-volume production.

The forged cup face QUATTRO FORGED FACE engineered with patented technology is crafted with extraordinary technology that cannot be imitated by any other. Complex wall thickness according to designed value is attained from high-strength titanium round bars in a single forging process. No margin was taken for the repulsion coefficient, allowing the product to be made with high repulsion performance.

Message from the Development Team

To be frank, we were hesitant on developing drivers when we launched PROTO-CONCEPT.

Many major global companies put in significant R&D budgets and human resources for drivers these days to compete their performances. We felt it was reckless to go against these giants.

Our encounter with a Japanese manufacturer that possesses globally unmatched and exceptional forging technology, however, overturned such thought. They inspired us to create an unprecedented driver through pairing their patented technology and our PROTO-CONCEPT idea of awakening golfers’ senses.

And that is how the C01D driver was crafted.
We are confident that the C01D is the one and only, best golf club unlike any other drivers today.

The data is based on 3 testers hitting 5 shots each.
All swing speeds demonstrated outstanding ball speeds and marked smash factors of around 1.50.
In addition, testers with high swing speed marked strong trajectories with lower spin. The slower swing speed tester slightly increased spin and improved carry. All three tester commented on the driver’s ease to hit and great feel, as well as pointed out how their swing speeds actually improved.

*Three testers whose swing speeds differ tested shots outside. Course balls with high spin were used.
Ball flight tracker TrackMan was used to measure trajectory.
