You Are Going to Love 3 Wheel Pitching Machines!
Three rheostat knobs (think light dimmers) that control three speeds of three motors which drive three wheels (that grab the softball better than traditional two wheel models!)
What this means to you is that balls are thrown with tighter spin and improved accuracy while needing less energy from each motor & wheel for longer life. It also means the motors recover faster so no waiting between pitches.
The smart design allows the batter to see the ball from the "pitcher" all the way through the process instead of disappearing between the wheels (which has always been an issue in that it can affect a batters timing...this creates a more game-like batting practice!
