Probe Golf, Inc.
In 1993 I invented, patented, and sold 125,000 ($15 M in sales) golf putters with my inverted shaft! Now I have a new, better putter!
My new putter allows every golfer to intentionally impart side-spin on the golf ball to cancel the break in tough breaking putts, making them easier to make! Every one of the 25 million golfers in the U.S. will benefit!
