Checking a used set? These are published factory specifications, not measurements of the clubs you own. Loft, lie and length may have changed through custom ordering or later work.

How to identify this generation

  • Look for AP3 and 718 markings; AP1 and AP2 are separate head families.
  • Use the official 718 AP3 page to compare the cavity before treating these as the correct angles.

What to notice in the specifications

  • AP3's 7-iron is 31°, one degree weaker than AP1 718 and three stronger than AP2 718.
  • Its P wedge is 43°, matching the AP1 718 P loft, but not its 7-iron loft.
  • The manufacturer lists AP3 from 3 through W48.

What the chart cannot tell you

A loft figure alone does not predict carry distance or determine a suitable fit. Head design, shaft, strike, swing speed and delivery also matter. Check actual loft and lie with a qualified fitter when a used set's history is uncertain.
