The pro-level Ball Coach is a speed training tool and radar gun for player development through one-on-one coaching or self-guided drills and hands-free operation keeps it simple. By making crucial results like hitting power, pitching speeds, serving speeds, shooting speeds and throwing speeds instantly visible, the Ball Coach is the easy way to get better faster. The Ball Coach is the ideal choice for measuring ball speeds in baseball, softball, volleyball, tennis, lacrosse, hockey, soccer and football. Named Best of Show at the 2014 American Baseball Coaches Association national convention, the Ball Coach is the first pro-level radar gun specifically designed for coaching and training. Powerful features include hands-free Constant-On Mode (put all your focus on coaching and training, not the radar gun), easy automatic triggering (simply hold button down and release when speed appears) and built-in memory with the previous 25 speeds (keep track and review training lessons).
