The Franklin Sports Launch Line Hitting Trainer is the perfect batting practice training aid for all hitters to practice leveling their swing and driving the ball on all planes of contact. This hitting aid can be used with a partner or on your own for easy batting practice. Track the ball as it moves down the line and practice your swing on all planes as you try to drive the ball back up the line. This baseball batting aid gives real-time feedback on your swing as you train your hands to drive the ball back to the sender. Practice hitting pitches up or down in the strike zone, and work on lifting pitches to achieve the optimal launch angle. This easy to use hitting trainer can be set up in minutes and doesn't require shagging balls or a batting practice pitcher for players to practice their swing. Take batting practice right in the backyard with this compact batting practice aid. The attached Indestruct-a-Ball plastic baseball is built to last, so you can take swing after swing without cracks or dents. Practice striking the ball cleanly and shaping your swing to drive the ball with power. You can even bring it to the field for easy batting practice before games.
