The Heater Starting Pitcher is a single speed Soft Lite-Ball Pitching Machine. It pitches fastballs, inside breaking balls, and outside breaking balls. The powerful A/C motor throws soft lite-balls or wiffle balls at 40 miles per hour. The Starting Pitcher also includes an automatic ball feeder that holds 12 soft lite-balls. Just turn on the feeder and each ball is dropped into the pitching machine every 9 seconds. Take batting practice without the need for another player! And with a simple swivel adjustment you can also hit fastballs and curve balls. Plug the Starting Pitcher into any standard wall outlet.
