发明名称 Golf swing training device
摘要 A golf club shaped swing training device provides visual indication of club position during a club swinging motion. A first laser diode produces a first laser line from the upper end of the shaft and second and third laser diodes produce second and third laser lines respectively from the bottom face and the front face of the head portion of the device. Each of the laser lines emanates from the device as a concentrated beam to impinge and be readily visible on a training surface remote of the device for independently tracking movement of the shaft, the bottom face and the front face of the head portion of the device.
