By stabilizing the thumb, the grip stays in the proper position throughout the swing. This results in increased muscle memory and straighter, more consistent shots.
The Thumb Caddy's unique design also prevents you from gripping the club too tightly, what the pros call “the death grip”. You should hold the club lightly enough to allow for plenty of wrist freedom and feel, but firmly enough to maintain control throughout your swing. With the Thumb Caddy you are now in control of your grip.
Simplicity is the key: Just Snap It, Fit It and Grip It. The Thumb Caddy fits on the shaft of any club and can be used by both right and left handed players. Using both thumbs spread it open and slide it up on the grip aligning its center with the club face. Right-handed golfers rest their left thumb in the cradle of the Thumb Caddy to ensure proper grip position; left-handed golfers rest their right thumb into the Thumb Caddy to ensure the correct grip alignment. With a solid grip everything else falls into place to develop a more effective and repeatable swing.
