You’ve heard it a thousand times, the putting stroke uses big muscles, not small fast-twitch muscles.
This product is designed to nest right up next to the Classic EyeLIne Putting Mirror or the Special Edition EyeLine Putting Mirror. (see below)
The Shoulder add-on for the EyeLine Putting Alignment Mirror gives an expanded view of the shoulder alignment. Match your shoulders to the mirror lines and you are ready for more solid, end-over-end rolls. No more slicing putts.
Just slide the shoulder mirror against the bottom edge of the putting mirror. No attachment.
Turn the shoulder mirror around for a great arc template, too.
