Is this any use for measuring release ?
 

Take a club-length dowel and place a metal ring ( eg. curtain rail ring, large annular body-piercing ring :rolleyes: etc) over it. Go to the top of your backswing so that the ring rests on your hands. Make your downswing movement and mark / video the spot on the ground where the ring falls off.

It seems to a beginner like me that a weak, early release causes ring to slide off early in downswing and land outside my right ( right handed) foot. A max delay snap release causes ring to slide onto, or even in front of, the ball.

Easy to do indoors.

I know that this is really just a version of many commercial products ( eg "swingsetter" by Leadbetter / "Power release" by rover golf ) but it is cheaper and gives a visual marker of the release point where the other products rely on auditory markers.

It is hard to document auditory markers in an objective way for reference over time but a visual marker can be captured on video, or on the ground, much more easily and compared with future/past results.

It is also another use for the dowels!!

Is this a useful image or am i cultivating a motion that will lead to disaster when i actually hit a ball?

Thanks for any comments

This is a great improvisation.

Ultimately, being able to execute it on such devices is no guarantee that you are actually replicating the delayed release.

The best way to ensure that you are actually using a delayed release is to use a video camera.

Your "weak, early release" sounds like an improper downstroke sequence (6-M-1) where you throw the Clubhead from the Wrist (6-D-1).
