I love the shot tracer/trackman during broadcasts and find myself disappointed when a shot doesn't have the shot tracer with it. In recent years they have married the shot tracer with trackman data of ball speed, apex and even curvature. I also really appreciate when they superimpose the animation of the hole where you can see the trees/hazards/fairway as the ball flies to see where the ball is flying.
Is it the best golf broadcasting innovation ever? You can see where the ball is going in relation to the hole layout as opposed to some on course broadcaster sayin, "this is headed left."
I can't imagine going back to watching golf without this innovation without being disappointed.
