Geoff,
I would love to get your evaluation of our
Eyeline Putting Plane.
It is very similar to the Tru Plane Trainer, but since the Plane attaches to a mirror, the player can also check his eye position, his shoulder alignment, etc.
We have some video on our website showing how a laser line, attached to the putter shaft, travels perfectly along the path of the putt when the putter is taken back, up, and inside, and then through, up, and inside. The angle of the plane is 18 degrees.
We sent out 4 prototypes to tour players, and we have had almost 20 new requests in the last 2 weeks. Ted Purdy worked on it during Master's week - prior to the MCI. Those results are pretty amazing.
Thanks for your insights.
Sam
