Golf practice device

摘要

A golf practice device having a base supporting a substantially vertical fixed shaft which supports a wheel mounted for rotation about the shaft, and a ball tethered by at least one flexible cord to the wheel. The device also includes an optical sensor which is disposed adjacent to the wheel to detect the rotation thereof and to output a signal indicative of the rate of rotation. This signal is sent to a processor which calculates the free distance of travel a real untethered ball would have traveled and outputs a signal to a display to indicate the free distance of travel to a user.
