In this video golf tip PGA Teaching Professionals Pete Styles and Matt Fryer discuss how destructive a duffed iron shot can be and how you can remove this from your game.

I don't think there's a more frustrating shot than being in the middle of the fairway having hit a great tee shot 8 iron in hand green sitting out in front of you and you play the next shot from about here and you hit an absolute complete duff. Bit like that you mean? That was an excellent example, you really practiced hard on that one, I am quite good at the duff.
