All golfers, even the best players in the world, miss the center of face from time to time. And when you lose speed relative to a center hit, the ball doesn’t roll as far as you intended, so you miss more putts or leave them farther from the hole. Now with Ai-ONE Milled, Callaway’s industry-leading Artificial Intelligence design and super-computing capabilities have merged to create the most advanced insert in golf, with consistent ball speeds across the face.

Ai-ONE Insert: Designed using Artificial Intelligence, Callaway has created contours on the aluminum backer of the insert to promote consistent ball speed across the face. They’ve co-molded a grooved White Hot urethane layer into that aluminum backer for the classic White Hot feel that Tour players and amateurs love.

Ai Window: Callaway's designers and engineers developed a Panlite window, which is a unique automotive grade polymer, that allows showcasing the unique topology of the back of the insert.

SL 90 Shaft: A lightweight steel shaft with 20-30 grams (depending on the grip) of counterbalance weight in the butt end. This is an evolution of Callaway's Stroke Lab Weighting that will appeal to even more golfers.

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.

Interchangeable Front Weights: Available in 5, 10, 15 and 20 grams these removable weights allow you to dial in your head weight to your exact preference. Model: 73034X3500.
