question: an old fashioned launch monitor?

[redan]

Many years ago, when dinosaurs roamed the Earth, I was told that if I placed an iron on the ground and stepped on the face with my foot, when the iron came up (sorta like stepping on the teeth of a rake-- ouch), the angle of the shaft would be the angle the ball would take leaving the club face. So I could tell for instance if I had tree limbs or something in front of me whether an 8 or 7 iron say would nip the branches. You know, all these years I've kinda used it as a guide. Is there anything to it?

Thanks. Redan
