High Density Tungsten is precisely placed low and in the toe of the long and mid irons, produces a lower centre of gravity (CG) for a higher launch angle. The improved launch allows for stronger lofts, which increase speed for even more distance. The high density tungsten also moves weight to the perimeter, increasing moment of inertia (MOI).360º Undercut CavityAn extreme 360º Undercut Cavity results in a large, thin, unsupported face area, creating a Thin Fast Face that flexes more at impact. The face is constructed from specially heat-treated 17-4 stainless steel for strength, which increases both speed and launch for more distance. Additionally, the deeper undercut creates discretionary weight that allows industry leading use of high density tungsten.Titleist AP1 716 Steel Irons Features:Improved FeelAP1 models provide solid feel at impact with improved turf interaction. The irons have optimised CG heights, low with a slight progression through the set which are positioned closer to the point of impact for solid feel. A higher MOI through the increased use of high density tungsten, adds stability and further enhances the solid feel. The Titleist AP1 716 Irons has a new pre-worn leading edge and cambered sole that reduces digging and allows a smoother entry and release from the turf.Loft ProgressionOptimised loft progression facilitate shot-stopping distance at both ends of the set and creates preferable yardage gaps. Strong lofts in the short irons provide distance with trajectory and spin control. Strong lofts in the long irons provide distance with proper launch, longer carry and shot-stopping ability. Compared to other game improvement irons, new AP1’s provide tighter dispersion at the short end of the set where control is paramount, and less yardage gap compression at the long end of the set where launch and trajectory are critical.We are a professional shop with 26 years experience, for more information on any of our products please contact us.
