When we look at golfers set up there are lots of different variables including foot positioning, spine angle as well as ball position. These variable changes as you switch between longer and shorter irons thus potentially causing more room for error. With ‘One Setup‘ and ‘One Swing’ you can simplify the process. Every golfer has their favourite club and for many it is a 7iron. With these irons you will find new confidence in your game allowing you to play any iron as if it were your trusty 7-iron.

Michael Townsend, PGA Professional and Head of Fitting at Duncan Lambert Golf had this to say about the new Cobra Iron. “Cobra has produced an exciting game improvement iron, which is easy to use and has simplified the game to the customer.”



The standard irons will come in 37.25″ whether you have the set fitted in Steel or Graphite Shafts. Should you need your shafts longer or shorter each iron would match that specification. For example if you were 1 inch longer all the irons would be 38.25 inches. The overall aim of these irons is to make the game simpler and easier to play.
