Proto Concept C03TC Irons 5-PW ( 6pcs )

Introducing Proto Concept C03TC Iron.

Crafted with unparalleled ultra-precision soft iron forging.
A tour cavity back evolved through a center of gravity designed for each club number.

A tour cavity back with high-precision soft iron forging crafted with minimal manual processes using an ultra-precise forging process and CNC undercutting.

While succeeding the functionality of the previous C03 model which was already close to perfection as a soft iron integrated cavity back iron, the center of gravity design was developed for each club number through using 3D CAD. The C03TC was crafted to become a world-standard soft iron forged iron with enhanced balance as a set, pursuing functionality for each club number in response to feedback received at U.S. tours.

Center of gravity design for each club number by 3D CAD

While utilizing the center of gravity design of the previous C03, which reached near limits as an iron made with a single material, the center of gravity design for each club number was adopted to pursue optimal functionality except for each and balance as a set.

The maneuverability required for advanced golfers is achieved while the head movement stability was enhanced to align the sweet spot and desired direction of the club. Furthermore, the center of gravity positions was optimized across all club numbers by using 3D CAD to improve the ease of handling as a set. The lineup also includes a #4 iron that provides forgiveness while retaining the same flow as other club numbers.

Precision-integrated soft iron forging and CNC undercutting (#4-#7)

Integrated soft iron forging provides a pure and crisp feel when hitting. The ultra-precise soft iron forging and CNC machining which are distinctly different from traditional forging methods eliminate product deviations and deliver significant advantages in shape uniformity.

The CNC undercut shape, with newly developed depth, width, and angle for each club number, has a lower center of gravity and an expanded sweet spot. Forgiveness and ease of raising the ball for the long to middle irons have significantly been improved.

3D head shape that materializes PROTOCONCEPT's dedication to shape

The center of gravity position of the club head and sole shape has been optimized for all club numbers, assuming both good lies as well as difficult conditions and use on all types of courses, including when teeing up. The design offers even greater advantages to intermediate and advanced golfers who can make use of this while feeling the center of gravity.

The top blade, back face, and undercut area are all designed to appear parallel to one another, creating a shape that is easy to position squarely and providing a sense of security and a good image of the trajectory.

SPEC

*For every 0.25-inch change from the standard length, the balance changes by about 1 point.
