The 12 degree Putting Arc is based on natural body movement and can be learned and repeated quickly. Results are visible within days, with significant progress achieved without thousands of repetitions.
 
The putter head moves in a perfect circle (radius R), whose projection onto the ground is an ellipse, the same shape as the putting arc.
 
The putter always on "plane" (the sweet-spot/spinal pivot plane). The intersection of this plane and the ground is a straight line, the ball line/target line.
 
The putter face is always square to the plane. It is only square to the ball target line at the center line of the Putting Arc. It guides an inward-squared-inward putting stroke.
 
In this putting motion, the hands, arms, and shoulders move as a whole. The correct Putter Face follows the correct path for putting without any manual manipulation of the hands or arms. It all happens automatically.
 
12 degree Putting Arc is a good partner with Putting Template or Putting mats, to help easily control the Putter face arc.
 
The 12 degree Putting Arc is made of nylon, has a good texture, feels heavy, and weighs approximately 860 grams. Both ends can be secured with Tees
