At the Quicken Loans National and the HNA Open de France, players began testing Titleist's new 718 irons. The AP3 is drawing the clearest attention, with photos suggesting it sits between the larger AP1 and smaller AP2.
A 2026 catalog listing placed a used Titleist 718 AP3 set at $433.98, against an estimated market value of $506. That is a later resale-market snapshot, not the model's original launch price.
What the AP3 photos suggest
Titleist had not shared specifications, so the AP3's construction and performance remained unconfirmed. Its apparent size falls between the AP1, aimed at higher-handicap golfers and described as Titleist's longest-flying iron model, and the AP2, one of the most popular iron models on the PGA Tour.
The available search results do not independently verify exact AP3 lofts or head construction. They also offer no confirmation of set makeup or face materials. No measured performance data was available.
Available GolfOnline listings concern current Titleist T-Series irons, not the 718 AP3, so they cannot verify the older model's specifications or performance claims.
Poulter's mixed setup offers a testing clue
Ian Poulter posted photos of the new irons in his bag on Instagram. He appeared to be testing AP3 and T-MB irons in the long and mid irons, with AP2 and MB irons in the short irons.
The setup raises the possibility that AP3 long irons use hot faces like the 716 AP1 and T-MB, adding height and distance. The photos do not confirm that design or show a measured benefit.
Titleist says product seeding and player validation are important parts of its go-to-market process. The company uses them to assess whether new products meet its standards for innovation and performance. It also evaluates quality. Further details were expected closer to a retail launch anticipated that fall.
The available research does not independently corroborate model-specific statements or player validation data. It also contains no official specifications for the 718 AP3. Current Titleist product listings do not establish details for this older model, as shown by GolfOnline's current iron listings.
The AP3 may bridge two established iron profiles, but its construction and benefits remain unverified. Until Titleist releases specifications or testing evidence, the photos offer an early look at tour evaluation, not a basis for choosing or replacing irons.
