Two new models — the Phantom 11R OC and Studio Style Fastback OC — bring OC technology to each of Scotty Cameron’s putter families in familiar mallet and mid-mallet profiles.

“Onset Center” refers to the putters’ shaft position, which is set back of the putter head’s leading edge (Onset) and in line with its center of gravity (Center). This tour-validated setup minimizes torque and simplifies the putting stroke, and its addition to the Studio Style and Phantom families gives golfers a new option within Scotty Cameron's range of existing shaft and neck configurations.

The new Phantom 11R OC is built off the Phantom 11 platform, a stable, high-MOI multi-material mallet design. The tour-inspired 11R shape features softer, more rounded edges than the Phantom 11 head, and the new model features a full chain-link milled face. The 11R has a single alignment line, which extends back to the shaft placement.
Features:
Low-torque design: Scotty Cameron OC putters feature shaft placement set back from the leading edge (Onset) and in line with the putter head’s front-to-back CG (Center). This minimizes torque and creates a square feel for golfers looking to eliminate face rotation. 
Traditional feel and feedback: The Phantom 11R OC model features Scotty Cameron’s chain-link face milling design across the face, while the Fastback OC model features the Studio Style lineup’s Studio Carbon Steel (SCS) face insert, also with chain-link face milling. Both designs dial in feel by softening sound while preserving feedback, which is essential in identifying strike location — especially in low-torque setups.
Minimal shaft lean: OC putters feature one degree of shaft lean, promoting a neutral setup and a natural hand position familiar to many of the best putters in the game. The subtle shaft lean also delivers unimpeded topline views at address.
Loft and lie customization: Adjusting the loft and lie angle on OC putters does not compromise low-torque performance, allowing golfers to make spec changes as needed.
Heavier head weight, custom shaft and grip: New OC models offer connection to the putting stroke through 15-gram heavier head weights (compared to standard Scotty Cameron models) and a custom black shaft with flex properties designed to match the weight increase without dulling feel. OC putters are also equipped with a tapered Matador Mid grip.
