Abstract: An adjustable golf teeing device for use on a standard driving practice range which provides adjustment of golf tee height similar to conditions normally encountered on a natural golf course. The device consists essentially of a base and a vertically arranged hollow cylinder with an aperture at the top of the cylinder. The base of the device is placed under a standard mat found at a driving range with the hollow cylinder extending through an opening within the mat. A standard golf tee may be inserted into a moldable wax contained within the hollow cylinder which allows adjustment of golf tee height to the desired position.
