Featuring Odyssey's next revolutionary alignment technology, the 1/2 Ball design frames the ball helping to center your impacts and improve your aim. Powered by our Ai-DUAL insert delivering consistent ball speed across the face with improved forward roll the Ai-DUAL Seven S is an iconic shape, and a modern classic with an angular design that makes it very easy to align. Its short slant hosel provides significant toe hang best suited for strokes with more face rotation and arc.
