The device was designed to train the wrists and forearms in 3 different motions that occur in a proper release of the golf club during a full swing — cocking and unlocking of the lead wrist, flexion (bowing) of the lead wrist and supination or rotation of the lead wrist and forearm without sacrificing the integrity of the flexed lead wrist. Simply put the Impact Snap is a grip with a noise-making ball extending from the butt end. By making the ball clack in the right place and rest against your trailing forearm, you’re training a good release. As Ben Hogan wrote, using the wrist & arms properly is a must if you want to play great golf. I have not had the opportunity to test the golf aid, but its definitely on my bucket list.
