there's no way to know exactly where the clubhead is by just monitoring your hands.
old drill:
open you palm flat out, facing the sky.
put the butt of your driver (or even your baseball bat) into the palm of your hand, so that it stands vertically.
Now, concentrate on the top of the clubhead, and try to balance it. Were you successful?
Now, try it but only look and think of your hands. You will have a hard time keeping the club balanced because your attention isn't on the clubhead, but just on what your hands are doing.
Now, what does this mean? You have to train your hands. But, when you're actually swinging, you better have your mind on what the clubhead is doing otherwise it won't be exactly where you need it to be.
