The Delta Putt was invented by Dave Grill, an accomplished golfer who won collegiate golf championships, competed in the finals of the 1981 National Long Drive Championship, and caddied for the 1979 PGA Tour Rookie of the year at the PGA Championship.
Despite playing golf at a high level, Dave had always been a self-described "streaky" putter, and after his flatstick let him down on an otherwise glorious trip to Bandon Dunes Golf Resort, he decided to do something about it.
His goal? Create a device that would do something that practicing on putting greens and putting mats could not. Namely, to show him the reasons WHY he was missing putts.
So, after much thought and tinkering and improving upon several prototypes, the Delta Putt puck-and-mat system was born.
As he said in a recent newspaper article:
It will identify even the most minor flaw in your stroke. You can see exactly what you just did in your stroke with the way the putt glides down the mat. And as Dave likes to say,
The puck does not lie.
Interestingly, the Delta Putt was not Dave's first sports-related invention. That honor goes to the Mitt Whomper, a device he invented to help form and hold the shape of his daughter's catcher's mitt. Dave's three children have enjoyed standout status in their athletic endeavors, too, enjoying success in softball, baseball, football, soccer, and of course, golf.
Dave is a graduate of Lewis and Clark college, recently retired after 25 years in the metals industry, and currently lives in Oregon with his wife, Kellie. As mentioned, the Delta Putt was not Dave's first invention, and most certainly won't be his last.
