SKLZ Hit-A-Way - Baseball Single hitters become doubles hitters with Hit-A-Way, the most effective and sport-specific trainer on the market. Improve your hand-eye coordination with this training aid that works as your own personal batting instructor. Easily adjustable to hit high, middle or low balls. You can also practice switch hitting. Quickly attaches to any pole or tree. It's recommended that you use a practice bat with your Hit-A-Way. Much like the balls in a batting cage, the durable materials are meant to last and should not be used with a high end aluminum or wood bat.
