STP Technology
A Tungsten plug in the toe of the 702 series serves two specific purposes: The weight redistribution perfectly balances the CG for optimal face control (ie. these irons don't have a left or right tendency). And the mass of the tungsten helps to maintain better distance on toe strikes.

Progressive Geometry
Each 702 iron features a specific geometry design on the back cavity/muscle that progresses through the set. This ensures optimal launch conditions from the long irons all the way to the scoring clubs.
