It is portable, accurate, and safe. It has provision for an additional external battery. Unlike other machines, it does not require extension cords or a generator at the playfield.

Most batters quickly learn to anticipate the pitch.
If necessary, the operator can help by synchronizing a throwing motion with each pitch. The changeup mode randomly varies pitch speed to distribute pitches around the strike zone for game realistic pitching. The machine does not presently throw curveballs. The machine helps players of all ages to improve their hitting and fielding. It weighs 30 pounds, complete with tripod and internal battery.
