US Patent 10124223 Low-interference golf tee saver set

A golf tee set is provided with a keeper for preventing a tee from flying into a driving range or being lost, in which a first golf tee is tethered to a second golf tee, wherein a first point of attachment of the tether to the first golf tee is free of interfering force on at least the first golf tee, and wherein the tether is constructed of a filament having less weight, stiffness and resistance to twisting compared to a minimum weight, stiffness and resistance necessary to cause interference with the first golf tee loaded with a golf ball. The improved tether system avoids using holes in the tee, which can lead to breakage during play, and is removable to allow the user to select different tees for different game circumstances.
