"Consistency in putting stems from creating consistently good starting positions
– I call these constants and they are:
(1) Constant Eye Position,
(2) Constant Hand Position and
(3) Constant Ball Position.
If you start in exactly the same position every time then you will develop a putting
stroke that repeats. The Optimizer prism consistently sets you in the correct position
for executing the perfect putting stroke, every time.” [Peter Cowen]
Off center hits are the major cause of missed puts
The sweet spot on any putter is just 3 millimeters in diameter and locating it accurately
is essential for consistent ball strike. The transposed parallax lines on the
Optimizer will locate the sweet spot to the nearest half millimeter.
