ABSTRACT:
A batting practice trainer includes a laser oscillator placed in a sensor unit configured to resemble a home plate. Three beams are emitted from the sensor unit in a predetermined pattern, so that the height, speed, and angle of elevation of a swinging bat may be calculated from the passage of the bat across the beams. This is accomplished without interferring with the batters' swing or substantially modifying the bat.
