Abstract: A golf puffer has a cylindrical tube mounted horizontally behind the putter face with its front end aligned behind the sweet spot. The rear end of the tube is open. This tube acts as a resonant structure producing an enhanced characteristic sound when the sweet spot on the putter face strikes a golf ball. In addition, the tube typically has a diameter larger than that of a golf ball. The golfer's view of the cylindrical tube enhances the golfer's ability to correctly line up a putt by using the visual peripheral corridor created when the puffer is swung back and forth over the golf ball along the golfer's intended swing path prior to addressing and putting the golf ball.
