"The Bataction Self-Trainer™ ball rotates at a high speed to give the batter practice hitting a moving ball. When the ball is hit, the ball rotates forward, slows down, and comes back to the batter for the next swing. The batter hits ball after ball without having to chase or gather balls. The machine can be used indoors or outdoors." If you are a parent or coach, ask yourself these questions: Is your player an underachiever at the plate? Is your player a future prospect that loves to practice and improve? Do you know that your player is a much better hitter than past performances indicate? Would your player be willing to spend just 1 hour a week performing exciting and fun drills that develop incredible skill and confidence? Did you know that for less than the cost of a new bat, you can purchase a hitting machine that can help make a young player's dreams come true? If you answered "YES" to any of the above questions, you are about to make one of the best investments you will ever make in your player's baseball future 1 - Heavy Duty Nedco/ Hit2Win Trainer Ball Impact Head (color choice white or optic yellow) 1 - 24" Support Housing Column 4 - Deluxe Heavy-duty steel groundpins 3 - "Tubed" BatAction PowerBands 4 - 24" Removable legs 1 - Adjustable Height Collar 1 - 25" Inner pivot axle 9 - Deluxe Quick Turn Adjustment Knobs 1 - Advanced Owners Drill Manual 1 - Deluxe 3-Hook Connector Arm 3 - Sand Bags with Ties (Indoor Use) 1 - BAM Insert/Locking Plate 1 - Deluxe Rotating Top Component
