Owned and used by MLB teams. This unit is 20% larger than the Elite Traveler, allowing for ball placement to the top of the hitting zone for all players. This machine is made of galvanized, industrial grade steel tubing and a patented bungee cord and home plate system that allows you to position the ball anywhere inside the strike zone. The Elite Traveler Pro also converts in seconds to a rebounder to work on pitching, fielding and throwing. Folds in half and into optional travel bag for storage or transport.
