Filming Your Swing
Unfortunately, Vijay's quote was taken out of context, misunderstood, or was simply untrue. Singh has used high-speed cameras to record his swing for years and maintains a large library of his videos. While practicing, he often has his caddie or others record his swing, and will stop to look at things and make adjustments.
I think that what Vijay Singh was trying to say is that he values function over form. That's fine - and something virtually every good golfer has in common. And while it's true that form follows function in the golf swing, the opposite is also true: function follows form. A high-speed video camera is a useful, valid tool in improving both the form and function of your swing.
