"The Putting Arc has helped me a lot.
It showed me my flaws and corrected my stroke. I used it all winter and came out
and won the first tournament at Hawaii."

Dana Quigley, Champions Tour

Welcome to The Putting Arc.

Learn about The Putting Arc (pat. pend.), a revolutionary new training device, which will guide you to a simple, repeatable, and understandable approach to putting. The Putting Arc will assist you in developing a confidence when standing over your putter felt by only a small percentage of golfers, a confidence in your ability to direct the golf ball exactly where you intend.

What is so new and revolutionary about The Putting Arc? Nothing and much. Nothing about the stroke is new. Almost all of the great putters of the modern era use it. What is new, is the combination of ancient mathematics, a simple and self-explanatory instructional outline, and state-of-the-art manufacturing technology. The mathematics define the perfect putting stroke, the instructional outline explains and trains the perfect putting stroke, and state-of-the-art manufacturing techniques create a device which quickly teaches you the perfect putting stroke.

The good news is...most golfers see a marked improvement in their putting strokes in a day or two. You don't have to do it 20,000 times to get better.

The MSIII
The newest model is a lighter composite material that is light enough to carry to the course to practice with.

The Putting Arc Works Because…
Its based upon natural body movement which can be quickly learned and repeated. Results can be seen in several days … 20,000 repetitions are not required.
The club head travels in a perfect circle (radius R) and the projection of this circle on the ground is an ellipse in the shape of the Putting Arc.
The putter is always ‘on plane’ (the sweet-spot/spinal pivot plane). The intersection of this plane with the ground is a straight line, the ball/target line.
The club face is always square to the above plane. It is only square to the ball target line at the center line of the Putting Arc. You are learning an inside to square to inside putting stroke.
In this perfect putting stroke, there is only one moving part. The hands, arms and shoulders rotate as one unit. No manipulation of the hands or arms is required to follow the correct path with a correct club face. It happens automatically.
Note to ‘Straight-Back-Straight-Through’ Putters:
There are only two ways for the putter to travel straight back and straight through:
1. The pivot point (spine or shoulder joints) must be perfectly over the ball.
Or
2. You must manipulate the club face during the stroke
Both are unnatural, require many moving parts, and are difficult to repeat consistently. The Putting Arc can cure the bad habits you have formed trying to make the putter go straight back and straight through.
 
 The Putting Arc... is an Ellipse
The Putting Arc works because it guides the putter head in pure planar rotation about an axis which passes through the golfers spine, somewhere between the shoulders (the dashed line in fig. 1). This means that the hands, wrists, elbows and shoulders all stay connected throughout the putting stroke. The Putting Arc has radial lines on its top. This important feature shows the correct club face alignment at each point in the stroke. This alignment is just as important as the club head path!
 
Mathematically speaking the putter head actually moves in a perfect circle. But since the axis of rotation is inclined relative to the putting surface the putter head motion projects onto putting surface as an ellipse. (Teaching pros if you don't believe us, contact us about 'Iron Archie', a robot demonstrator/teaching aid that proves The Putting Arc concept). This ellipse (the light colored shape ) is the mathematical basis for The Putting Arc. 

The actual dimensions of The Putting Arc ellipse are defined by the location of the center of rotation of the putter head. (This point is located on the golfers spine somewhere between the shoulders.) Surpriseingly, the dimensions of The Putting Arc ellipse are similar for all average size golfers. There are only a few thousandths of an inch difference in ideal shape of The Putting Arc for a 5'4" golfer and a 6'2" golfer (assuming a typical putting stance). For golfers with unconventional stances or people who simply want an ideal match we can generate a custom Putting Arc. The custom Putting Arc will come precisely ground to your dimensions along with a CAD plot showing the variation from the standard arc.
