Abstract: A strike zone indicator apparatus has a mount positioned in relation to a home plate and away from possible interference. First projectors connected to the mount project first beams related to the home plate. A measurer takes particular individual players measurements and a processor connected to the measurer and to the first projectors creates individualized upper and lower limits of strike zones according to the particular individual players measurements. Second beam projectors are connected to the processor for projecting second beams intersecting with the first beams for establishing above the preexisting home plate the upper and lower limits and the strike zones based on the particular individual players measurements from the measurer.
