Jeff Hull demonstrates the 'practice station.'
I think this is a pretty good setup and saw some PGA Tour pros doing this at East Lake or something similar last year.
The big thing for me is that Hull correctly shows where the clubhead should go after impact. I think this also teaches path correctly and more or less gets the golfer thinking about target golf and getting the ball on line quickly.
The only issue I don't like about it is that in order to hit it straight, the divot will go a tad left and if that is not presented to the golfer, it can cause some confusion.
