Golf Shop: MOMENTUS Swing Trainer Driver

"Introducing the new Momentus Driver Trainer, which possesses the same swing-enhancing qualities as the Momentus Iron Trainer. The Momentus Swing Trainer is a patented weighted training aid used by over 50 players on the PGA Tour, including 13 of the top 30 money winners from 1997 . David Duval, a three-time 1997 PGA winner, says, I swing the Momentus swing trainer 20 to 30 times each day. It has added consistency, strength, flexibility, and clubhead speed to my swing. Available in right hand only."
