Even the world’s best tour players sometimes miss the centre of the face. When you don’t hit the centre of the face, the ball loses speed and doesn’t roll as far as you intended, resulting in longer return putts and more putts per round. With Odyssey Ai One, Callaway, using artificial intelligence and advanced computing capabilities, has created its most innovative insert yet. The putter’s multi-material construction includes unique contours on the back of the face, which give you a larger sweet spot and minimise ball speed loss on off-centre contacts. The groundbreaking Ai One insert delivers more constant ball speeds, even on off-centre hits, bringing putts up to 21% closer to the hole. The face is forged in titanium and equipped with the popular White Hot coating.
