This invention concerns an adjustable height practice golf tee for use with any of the existing golf hitting mats used at or incorporated into golf driving ranges, public and private indoor hitting areas, golf club fitting, testing and swing teaching stations, electronic golf swing analyzers and golf simulation video games. The invention incorporates a hidden thread design into two-piece and three-piece models to provide a greater range of adjustment and better durability than older designs. The inventive device uses a passive capture design which allows assembly without additional fasteners or retaining devices while preventing disassembly during use. A combination three-point ball seat reduces the tee's mass and effect on the ball launch while acting as a handle to facilitate precise and easy height adjustment.
