Proto Concept Irons C05
US$ 1,920.00
Tour pocket cavity iron with enhanced distance,
together with straight-line performance
and maneuverability sought by tour professionals
Distance, maneuverability, straight-line performance, forgiveness, and feel.
This tour pocket cavity iron satisfies many elements sought for an iron.
SAE8655 chrome molybdenum steel is used in the proprietary structuring with thickness deviation.
A model that optimally allocates excess weight to enhance straight-line performance and forgiveness, while increasing distance performance through high rebound.
SAE8655 chrome molybdenum steel is used
in the proprietary structuring with thickness deviation.
SAE8655 chrome molybdenum steel tougher than soft iron is used for the face.The creation of excess weight and a deeper, lower center of gravity, results in the ball rising easily and straight ball flight.
The overall thickness of the face is set at a slightly thick 2.7mm to deliver the feel of a single forged cavity iron, and the center left and right areas of the face are thinned to 2.4mm to enhance distance while maintaining the feel when striking.
Optimized center of gravity design that
delivers performance needed for irons
Enhanced mis-hit forgiveness and straight trajectory are achieved while having the same face size as normal cavity bacs through pocket cavity structuring and a clubface designed with thickness deviation.
The C05 has both a sharp appearance and maneuverability, such as high controllability and pulling out of the rough, that can withstand the demanding requirements of professionals and advanced players.
