Abstract

A device for estimating the range of a struck ball includes a backstop, at least one velocity measuring device, a data processor having a data structure communicating with the velocity measuring device, and a display communicating with the data processor. The range of a struck ball is estimated by measuring the velocity and departure angle, or alternatively, the horizontal and vertical velocities of a moving ball. The measurements are communicated to the data processor. The data processor calculates the range using formulae stored in the data structure or extrapolates the range from a database stored in the data structure. The range may be further manipulated to take account of environmental factors and factors unique to the player. The range is displayed at the display.
