Use this Phoney Hole set to practice Dave Pelz’s theory on successful putting where the chance of making putts is optimized when the ball rolls at a speed that would stop 17-inches past the back edge of the cup, if it misses. 

Designed to help you more accurately see your line & speed on putts of all lengths.

Phony Hole has a white line (with a 17-inch reminder) on one side, which can be placed to help you find the incoming line & break of your putts.

Slightly smaller than regulation.
