The new Phantom OC Spec III putters take their name from the automotive world, where "Spec III" denotes a fully optimized build with every part working in sync. Cameron's version is an all-black package (PVD finish, black steel shaft, black mid-size Matador grip) with three high-visibility sightlines for alignment.

The limited offering comes in two models: the compact, winged Phantom 5 with an SCS insert, and the rounded, high-MOI Phantom 11R, also available in left-handed.

The OC version differs from the traditional Phantom, with the shaft sitting behind the leading edge, in line with the center of gravity (CG), to reduce face rotation. The putters retail for $800 and hit shops on Oct. 1.
