Get your own electronic personal pitching coach. The Radar Pitching Trainer measures pitch speed, calling balls and strikes and simulating at bats. The built-in radar displays pitch velocities from 20mph to 99mph and has a nine-quadrant strike zone for calling balls and strikes. It works at baseball, little league and fastpitch softball mound distances. The Trainer simulates both and at-bat and half inning and keeps track of cumulative pitch count, balls, strikes, outs and walks. It’s like having a 35 pound virtual umpire who is always right, runs on D batteries and won’t throw you out of the game for yelling at him.
