Callaway Mens AI-Duel Square-2-Square MAX Half Ball Putter

Callaway Mens AI-Duel Square-2-Square MAX Half Ball Putter 

The AI-Duel Square-2-Square MAX Half Ball delivers the highest MOI in the Square-2-Square lineup combined with the intuitive Half Ball alignment system. This putter is engineered for golfers who want maximum forgiveness with a visual that makes squaring up effortless. 

Features

• Zero-Torque Center Shaft Design: The shaft aligns directly on the center of gravity plane, creating a reverse-torque toe-up position that naturally keeps the face square throughout your stroke—the opposite of traditional toe hang. 
• MAX High-MOI Shape: The largest, most forgiving head design in the Square-2-Square family delivers exceptional stability and resistance to twisting on off-center contact. 
• Half Ball Alignment: A semicircular alignment aid helps golfers visualize proper ball position and ensures the face is perfectly square to the target line at address. 
• AI-Designed Insert: Artificial intelligence created optimized contours on the aluminum backer to promote consistent ball speed across the entire face, even on mishits. 
• White Hot Urethane Face: Soft, responsive feel combined with AI-engineered speed consistency provides both feedback and forgiveness. 
• Built-In Forward Press: The 3.3° forward shaft lean pre-sets your hands, eliminating face opening through impact. 
• SL 90 Stroke Lab Shaft: Counterbalanced steel shaft enhances tempo consistency and stroke stability. 
• Oversize Grip: Secure, controlled feel optimized for the Square-2-Square design.
