发明名称 Practice device for golfers
摘要 A portable Golf Swing Practice Device designed to train the Golfer in how to develop a full swing. This device responds to a full swing by returning the tethered golf ball to the original general tee off area or beyond when struck with the golf club in the correct fashioned, a full swing. The tethering is accomplished by the use of ground attachment, a dacron line and a nylon stretch cord attached to a golf ball, assembled in such a fashion as to allow consistent repeated use. By seeing these results the Golfer can develop a full swing which in turn will develop a better Golfer.
