Abstract
Abstract The device of the present invention is intended to assist in developing the correct swing of a golf club. Briefly, the device includes a base plate for locating or positioning the feet, a loop adapted for encircling the neck and a flexible link between the base plate and neck loop. The flexible link includes a pulley to hold the loop, a swivel and an adjustable break-a-way coupling which may be in the form of interlocking male and female parts, held together by magnetic attraction, which will disengage if an incorrect golf swing occurs.
