HOW the putter key works
How Does The Putter Key Help Improve My Putting?
The Putter Key uses our Shape-Lock Method™, a visual targeting system made of a circle and directional arrow. This pattern trains your eye to aim square and stay on path, even when your perception shifts. It gives your brain something simple, repeatable, and accurate to lock onto from any angle.
Why is it Better?
Most putting aids are bulky, static, or take too long to set up. Unlike the alginment stick shown here, Putter Key moves with you, instantly improving how you aim during your normal warm-up routine. No cords. No apps. No tricky devices. Just better putting.
BETTER PUTTING BACKED BY SCIENCE
The Putter Key addresses three essential aspects of putting: centering, aim and path.
Developed over the course of two years by a renowned European golf instructor and a former marksman, the patented Putter Key design utilizes shapes (rather than lines) to assist in aiming the putter face and develop a straight path.
The Putter Key is lightweight, carbon fiber and highly portable and applied in a matter of seconds with an engineered adhesive that easily affixes to the top of your putter, adding no time or effort to a player’s existing routine. It helps you see true alignment and groove your putting path. Putter Key customers have seen significant improvements to their putting success in the three and ten foot ranges.
The Putter Key™ is designed to help you perfect your putting angle and increase your putting success. Seasoned golfers know that just a two-degree face angle error causes putts to miss by over two inches from a distance of 5 just feet. The Putter Key's precision system eliminates these costly mistakes, turning near-misses into made putts.
CENTER
The Key™ is the width of a golf ball, showing you the exact center of the face and training for proper placement.
AIM
Our proprietary design utilizes shapes, not just lines, for visual alignment, training to help you better aim the putter-face, which is essential.
PATH
The Key trains your back stroke using visual cues to ingrain the correct muscle memory. Draw the arrow back to the circle to create a correct path without outside manipulation.
the physics behind the putter key
The Putter Key leverages cutting-edge putting science to combat the natural challenges that plague 97% of amateur golfers. Here's the breakthrough approach:
-
Conquers Parallax Effect: This patented golf putting aid uses specially designed shapes that eliminate the visual distortion (parallax) that occurs when your eyes shift from behind the ball to your putting stance. The result? Perfect putter face alignment every time.
-
Shape-Based Alignment System: Unlike traditional putting training aids that rely on confusing lines, The Putter Key uses intuitive shapes that your brain processes more accurately, making better putting alignment effortless and automatic.
-
Path Training Technology: The integrated arrow and back target circle system trains a straight takeaway, promoting the correct stroke path that's essential for consistent putting performance.
Instant Feedback Loop: Each practice stroke with this golf putting aid provides immediate visual confirmation of your aim and path, accelerating skill development and muscle memory formation.
