Introducing Astro Tour V501 Irons from Masters! Astro Tour V501 irons are made with forged S20C mild carbon steel featuring an undercut cavity back shape. The undercut cavity design allows further lowering of the CG as well as improving MOI and helps create softer feel at impact. Although the Astro Tour V501 irons are a forgiving under cavity back design, it is also designed to provide great workability and excellent turf interaction preferred by better players. Another feature of the V501 irons are the addition of two 5g tungsten weight screws on the back which helps with lowering CG that helps with easier launch. The Tungsten weight screws also helps with creating a larger sweet spot and a head that creates stronger impact. Easy to launch, larger sweet spot and stronger impact are 3 of the most important design characteristic for optimal distance performance in irons. The face features precision laser milling which creates consistent friction that works to create consistent back spin on every shot. At a micro level, the surface of the ball pushes in further into the face milling creating a very soft compressed sensation at impact.
Astro Tour V501 irons have lofts that are modern with a 43 deg PW which seems to have become the norm for some one piece forged irons … perhaps should be referred to as “semi-game improvement forged irons?” Now that the multi-material irons are available in a more player’s category you need stronger lifts to keep up performance wise, yet the one piece forged will still promise better feel over the multi-material counterparts. Offset is quite small with a face progression spec of 4.0mm for the 5 iron and 4.5mm for 6-AW. Astro Tour V501 irons are offered with Fujikura 7 Axis graphite shafts as well as the popular NS 950GH and Dynamic Gold steel shafts.
