Callaway AI-ONE 2 Ball Double Bend Putter The Odyssey Ai-ONE 2-Ball DB putter stands out as the quintessential shape in the Odyssey line. This 2-Ball design, in its Tour Lined version, offers exceptional ease of alignment, enhanced by a double bend shaft that ensures a face-balanced configuration. Ideal for golfers with minimal face rotation and arc, this putter features the innovative Ai-ONE insert with an aluminum backer and a White Hot urethane striking surface, paired with the latest SL 90 Stroke Lab steel shaft. Even the most skilled Tour players experience occasional misalignment when striking the ball, resulting in reduced ball speed compared to a center hit and leading to putts falling short or veering off course. With the Odyssey Ai-ONE, Callaway has harnessed the power of Artificial Intelligence and cutting-edge computing capabilities to develop the pinnacle of golf insert technology. Featuring a multi-material construction, including intricately designed contours on the back of the face, this insert minimizes speed loss on off-center hits while significantly expanding the sweet spot. Our groundbreaking Ai-ONE urethane insert ensures consistently high ball speeds, even on imperfect strikes, bringing putts up to 21% closer to the desired target. AI-ONE INSERT Utilising Artificial Intelligence, Odyssey has meticulously crafted contours on the aluminum backer of the insert to enhance uniform ball speed across the entire face. Additionally, Odyssey has seamlessly integrated a grooved White Hot urethane layer into the aluminum backer, delivering the revered White Hot feel cherished by both Tour players and amateur golfers alike. AI WINDOW The designers and engineers at Odyssey have innovatively crafted a Panlite® window, a distinctive automotive-grade polymer. This innovative material enables them to elegantly display the distinctive topology of the insert's back, showcasing their meticulous design and engineering prowess. SL 90 SHAFT Introducing a lightweight steel shaft featuring 20-30 grams (depending on the grip) of counterbalance weight positioned at the butt end. This advancement builds upon Odyssey's Stroke Lab Weighting technology, extending its appeal to a broader range of golfers. UNIQUE NAVY BLUE PVD FINISH All of these putters showcase a stunning navy blue PVD finish, distinguishing them and imparting a luxurious, premium aesthetic. INTERCHANGEABLE FRONT WEIGHTS Offered in weights of 5, 10, 15, and 20 grams, these detachable weights provide the flexibility to fine-tune your head weight precisely to match your preferences.
