This Trident Putting String will help you with your alignment, your stroke and your green reading. The black legs are made from premium durable aluminum. The white elastic string measures 12 feet and can be stretch for longer putts.
The Putting String is used to check the putter alignment at address, also to help with the path of the putter, and then to visualize the ball starts on the correct line. It can be used for both straight and breaking putts. For both straight and breaking putts the string helps you see if you are able to start the ball on your correct start line under the string.
As seen on PGA Tour practice greens, this String is high quality and definitely a must have to improve your putting.
I can only recommend this High Quality String to work on your putting. Best Putting Aid by far!
