The PING Scottsdale TR Series Putters feature a variable-depth-groove insert for distance control. The grooves are deepest in them middle and get gradually shallower. This putter gets you greater ball-speeds when you want it and a sleek design that not only performs on the course, but is appealing to the eye.
Grooves are deepest in the middle and get gradually shallower to the perimeter of the insert. This counteracts normal loss in energy or ball speed to ensure more-consistent ball velocity across the putter face, even if the ball is struck off-center toward the heel or toe. PING® studies show a substantial increase in ball-speed consistency measured at nine points on the face.
Don't Change Your Stroke – Change Your Putter. PING® has tested hundreds of players both on and off the Tour over the years and overwhelming scientific evidence shows you will putt more consistently with a putter that's balance matches your stroke type. To help classify your stroke type PING® has classified every putter into one of three stroke types; Straight, Slight Arc and Strong Arc Stroke Types. Your stroke is determined by your closing angle and the amount your putter face rotates during the forward stroke.
