When I was starting out as a young PGA pro I used to put shafts down to show my pupils where I wanted them to aim.They would hit the ball fantastic, leaving me confused as to why I was teaching them at all. But results were not transferred to the course. Moving on to a playing lesson suddenly revealed all, the golfer in question could not aim the clubface at the target. Everything was aiming right and they looked a different golfer from the one I had seen on the range.
“Why do I hit it so well on the range and so badly on the golf course?!”
People hit the ball great when they don’t have to aim at anything. This is the main reason why most of us hit it better on the range than on the golf course. Where you aim determines how you swing.
When practising on the driving range it is important to pick out a target. Aimlessly firing shots into the distance fails to take into account the most basic principals of a good routine which leads to good alignment.
