Callaway's industry-leading, groundbreaking artificial intelligence technology takes a quantum leap forward in the new Paradym Ai Smoke family. Using real player data from thousands of golfers, including swing speed, club delivery, and face orientation just before impact, advanced machine learning created the most sophisticated iron face in Callaway history. Known as Ai Smart Face, this refined design optimizes launch and spin, resulting in a series of sweet spots spanning the entirety of the face that yield exceptional distance and tighten dispersion into the green. Callaway amplified Ai Smoke's already potent distance capabilities by using quarter-inch longer shafts in the mid and long irons. While there's no question a wider arc generates additional club head speed, it typically wreaks havoc on accuracy and control. So revolutionary is Ai Smart Face that golfers can reap the benefits of lengthened clubs while avoiding the typical pitfalls. Featuring a lightweight shaft and grip, the MAX Fast helps slower-speed golfers gain club head speed without a swing change. The irons' deep cavity back construction and precision tungsten weighting combine to lower the center of gravity, promoting a high, effortless launch.
