A great machine for improving your hitting right in your own backyard! The Slider Lite-Ball Pitching Machine from Heater pitches fastballs, inside breaking balls, and outside breaking balls. The powerful A/C motor throws lite-balls at variable speeds up to 60 miles per hour at 46'. The Slider also includes an automatic ball feeder that holds 12 lite-balls. Just turn on the feeder and each ball is dropped into the Slider pitching machine every 9 seconds. Take batting practice without the need for another player. And with a simple swivel adjustment you can also hit curve balls. Plug the Slider into any standard wall outlet.
