A practice/playing golf tee that is substantially indestructible. It includes a screw up/down golf tee head. When the head is screwed down the insertion tip parameter of the tee can be used. The insertion tip at the top of the tee goes into one of the existing holes in a practice golf ball or a regulation golf ball in which hole (s) are incorporated to accomadate the insertion tip. When the insertion tip is used with a wiffle type practice ball there is no spin resistance and a true flight path exists. A perfect grass lie can always be obtained. When the insertion tip is used with the much heavier regulation golf ball into which an insertion hole is incorporated, a spin resistance exists. This spin resistance can be adjusted by screwing the tee head up or down the top of the tee shaft. The spin resistance can stop a hook or slice. As the amateur golfer becomes more adept he/she can decrease the spin resistance by screwing the tee head up toward the top of the tee shaft. When the tee head is screwed up flush with the top of the tee shaft a regulation ball can be hit. In all uses of the tee a perfect grass lie can easily be obtained. Because of the anchoring variation parameter of the tee, the tee can be used for a continuous, convenient practice, or in playing the game of golf.
