Sail it! Toss it! Curve it! The Action Trac is specially designed for curves, throwing and catching. First, place the ball in the racket and let it roll down the Trac into position. Then, launch it - overhand or sideswing. The specially designed Trac sends the ball flying with amazing distance and awesome curve balls. For curve shots, bring your arm down and across your body with a sweeping motion. The ball will curve in the direction opposite of your swing! This set includes 2 jumbo sized rackets for easy catching and 2 special air-action balls.
