When Callaway launched its first generation of Apex Ai irons, the lineup included just two models – the Ai 200 and Ai 300. The Ai 200 was positioned as Callaway’s mainstream players distance offering, while the Ai 300 provided a bit more of a game improvement slant.
From the beginning, it was clear that 200 and 300 were just the beginning. The addition of new models with different numbers was all but inevitable, and with the release of the Ai 150, Callaway continues to build out – or perhaps more accurately, backfill – its Apex Ai lineup.
Understanding Callaway’s numbering system is straightforward: as is the case with Titleist’s T-Series, as the numbers get bigger, so does the size of the irons and the amount of forgiveness they offer. With that logic, the Ai 150 sits at the compact end of the Apex Ai spectrum.
The Apex Pro replacement
In simple terms, think of the Ai 150 as the replacement for the Apex Pro. It’s what Callaway is calling its fastest players iron – emphasis on players. This isn’t the fastest Callaway iron by any stretch, but it’s the fastest among clubs with a compact profile and represents the first mainline players offering to feature Ai Smart Face technology.
As a reminder, Ai Smart Face technology provides consistency on mishits while mitigating the impact of different lie conditions. It’s the same technology that’s proven effective in the Ai 200 and Ai 300, now optimized for the better player who prefers a more compact shape.
