A golf sling, using a tether made up of a joined resilient and a non-resilient line, uses a conventional golf ball attached to one end and an anchor attached to the opposite end to permit practicing golf in a limited area. A connector from the tether to an anchor permits using either a pin forced into the ground or a snap attached to a golf bag as an anchor. An adjustable device for the length of the resilient section permits selecting a length to change the tether characteristics appropriate to the club in use. The resilient portion can be made of a plastic coil or an elastic strap. A modification to the coil uses a spring through the coil to permit selecting a spring constant separate from the damping constant for greater flexibility. The golf ball can be permanently attached to the tether, or can be adapted to be readily changed by a variety of attachment devices. A tee and a tee holding ring can be attached to the tether for golf club wood use.
