ABSTRACT:
The wrist release is a device for monitoring wrist movement during a golf swing, and for learning the proper wrist movement needed to lower golf scores. The wrist release comprises an electronic circuit having signaling means and a unique transducer. The transducer comprises a housing having a bore, with a movable element disposed therein. The movable element is connected to means for monitoring a golfer's wrist movement. When the golfer has cocked his wrists properly, the movable element activates the electronic circuit, causing the signaling means to issue a feedback signal to the golfer. If the golfer does not cock his wrists properly, the feedback signal will be early, or nonexistent. In other embodiments, the device can be used to monitor arm extension, wrist cupping, or knee bending during a golf swing.
