What PING Says:
If you desire a compact, blade-style head and your primary goal is more distance, the new i530 is engineered to launch the ball higher and farther with the consistency and predictability to hit shots closer to the hole. Distance gains come from multiple sources including a highly flexible forged face in a hollow-body design that will add yards with tighter dispersion.

Details & Benefits:

• Forged Face - Like our previous player’s distance designs, a forged, highly flexible maraging steel C300 face is precisely welded to the 17-4 stainless steel hollow
  body, creating bending that produces big di
• Hollow-Body Design - The hollow body accentuates face bending that generates faster ball speeds and greater distance. Distance-optimized lofts help ensure max height
  with stopping power on greens.
• Confidence Inspiring - Blade enthusiasts will appreciate the compact head’s thin top line, narrow sole and shallow face height. The clean, premium look owes in part to a
  new machining technique that thins the back wall, saving weight to help with forgiveness and tighten dispersion.
• More Grooves, Spin - Precision-milled MicroMax grooves (tighter spacing, more grooves) ensure consistent launch and spin results and score-lowering performance from all
  conditions.
• Power With Feel - A lower CG is more aligned with where impact occurs, and a polymer precisely placed in the head improves feel and sound while maximizing face bending
  and ball speed. Tungsten toe screw and shaft tip weights for swingweight fine-tuning.
