The overspeed device helps the golfer increase clubhead speed.
The weight of the chain and ball at the end help with the feeling of creating lag in the swing. It increases stored power potential by making it easier to keep the right arm bent longer toward impact.
I am a dealer for the speedchain and overspeed device. Check out my site above for more info.
I updated the video description with more information about the overspeed device.
