  • Patent number: 6558302
    Abstract: A golf development and training device has first and second rods detachably connected at first and second connection points. Both rods contain multiple apertures for the receipt of one hooked end of a stretchable or elastic tube. The rods define a space between them when they are connected. A grip slidably engages the first rod and audibly clicks as it slides against the second rod when certain critical aspects of the training motion are correctly performed. At least one elastic tube is connected between the rod assembly and an attachment device which is secured to a stationary object that provides resistance and support. The attachment device includes vertical and horizontal rows of attachment apertures that receive the other end of the elastic tube. Multiple elastic tubes may be used, the number of which is dictated by the level of resistance desired during any particular exercise or training movement.
