Hold the snap swing against the golf club grip, approximately 1 inch from the lowest end of the grip.
Take the tail end of the SnapSwing and wrap this around the back of the grip.
Secure the tail in place by putting the ball attachment through the hole in the tail to secure the SnapSwing in place.
Over time, you will work out the best place on the grip to secure the SnapSwing. Ideally you want it positioned just below the lowest hand on the grip, so that the camera button can be activated by the thumb on the lowest hand on the grip.
PRO TIP: If you are having difficulty putting the ball attachment through the hole in the tail to secure the SnapSwing in place on the grip. Then move the SnapSwing down and attach it around the metal/carbon shaft of the golf club. Once attached pull the casing up and over the grip to the desired position.
