Indoor or Backyard Pitching Machine
The Grand Slam pitching machine is the most effective pitching machine on the market for developing the hitters and fielders hand-eye coordination. The self feeding reservoir holds up to 70 golf-sized Wiffle® balls and fires a pitch every 6 seconds. The reservoir is removable so an instructor can hand feed balls for the hitter. Each pitch is guaranteed to hit the strike zone in different locations. All you need is 16 – 20 feet of space. The pitch speed is adjustable to the hitters skill level and can throw a simulated pitch as slow as 20 mph or as fast as 95+ mph! Great for the garage, basement, driveway or backyard. Great for Coaches too; a hallway or classroom can become a safe hitting cage. Powered by a durable 4 hp blower motor the Grand Slam will last for years!
