The Putting Arc MS-3D

The Putting Arc MS-3D is the fifth-generation version of a putting aid that has been trusted by PGA, LPGA, and Champions Tour professionals for over two decades. Made in the USA, it's the #1 putting aid for the last 25 years. The 33-inch plastic rail serves as a physical guide to groove the ideal putting stroke path.

Weighing only 2.2 pounds, the MS-3D is 33" in length – enough for a full stroke for most standard length putts. The tool features two key components: the heel arc, toe arc and mirror make it much more versatile than any previous Putting Arc, and it has been received with enthusiasm by the many touring pros who have one. The adjustable mirror is possibly the most important part of this new product. It allows the golfer to check shoulder position and eye alignment for both the heel and toe arc strokes.

Like all of the other Putting Arcs, the curve of the MS-3D is based on the 2200 year old math formulas of Apollonius of Perga. With the Putting Arc you can quickly learn the inside-to square-to inside putting stroke used by the majority of the world's touring pros. Non-slip pads integrate with tee holes to anchor the MS-3D on grass, carpet or a mat, so it won't slide while you rehearse your stroke indoors or outdoors.

Best used as a dedicated practice tool for 5-10 minute sessions several times per week. Users report having much more confidence in their stroke after just 15 minutes of working with the MS-3D. When they went to the course, they almost still felt the arc guiding their putter head, with the feeling becoming more pronounced with more practice.
