The Perfect Jumper teaches the art of the perfect basketball shot. Fundamental training for all players from youth league to professional, The Perfect Jumper encourages the shooter to aim for the elusive center of the basket rather than the front rim. This shift in aim guarantees the satisfying swish as the ball hits the net, instead of bouncing off the rim. Since his retirement from football, former Indianapolis Colts player Quentin Coryatt has been hard at work promoting and marketing a device designed to help basketball players with their shooting.
