发明名称 Golf practice device
摘要 A golf practice device has a rotor with three simulated golf ball targets spaced equidistant from one another around the rotor, each target having mutually perpendicular webs and flanges forming a lightweight yet rugged construction readily molded in a unitary structure of synthetic resin material, and a housing within which the rotor is mounted for rotation about a horizontal axis and for ready removal and replacement. A plurality of telltales on the housing indicate any deviation from a true path by the head of a golf club swung at a target.
