No other trainer that I have seen does as much as the Bennett Tru-Putt. All of the putting basics are incorporated into this simple trainer: eye over the ball, alignment, stance, pace of putt, and squareness of your putter face are all easily practiced with the Bennett Tru-Putt. Some trainers may focus only on stroke (arc or straight back and thru), others claim eye over the ball, still others on squareness of the putter face. The Bennett Tru-Putt teaches ALL of the basics – therefore we call it the ultimate trainer. It is simple and effective – IT WORKS!!
