This is the baseball-pitching trainer that measures pitch velocity, calls balls and strikes, and simulates at bats. Built-in sonic radar measures pitch speeds from 20 mph to 99 mph and as balls land inside or outside the target's nine-quadrant strike zone, pitch velocity, balls, and strikes are displayed on the integrated LED. The unit counts and displays strikeouts, walks, and total pitches for a half inning for up to two pitchers at once. The radar adjusts to accurately measure pitches from 45' or 60' 6" away, accommodating the Little League and Major League Baseball pitching distances. The frame is made from durable 16-gauge steel with stainless steel hardware and folds for transport to a baseball diamond. Also measures fast-pitch softball from 40' or 43' away. Requires four D batteries that provide up to 100 hours of power. Assembly required. 58" H x 38" W (35 lbs.)
