Ai-One #7 Arm Lock Putter

The Ai-ONE #7 Arm Lock is an iconic shape and a modern classic with an angular design that makes it very easy to align. This version has a 380 gram head and is built at 42” with an Arm Lock grip intended to be rested on your forearm. This configuration makes this face balanced putter extremely stable. This putter features our Ai-One insert with an aluminum backer and White Hot urethane striking surface and our new SL 140 Stroke Lab steel shaft.

Ai-ONE Insert
Designed using Artificial Intelligence, contours on the aluminum backer of the insert promote consistent ball speed across the face. There is a co-molded, grooved White Hot urethane layer in the aluminum backer for the classic White Hot feel that Tour players and amateurs love.

Ai Window
Designers and engineers developed a Panlite® window, which is a unique automotive grade polymer, that allows the unique topology of the back of the insert.

SL 140 Stroke Lab Steel Shaft
This heavier steel shaft is designed to complement the heavier heads, longer grips and longer overall lengths of these models.

Unique Navy Blue PVD Finish
These putters all feature a beautiful navy blue PVD finish that really sets them apart and gives them a premium look.
