摘要: A golf practice apparatus includes an upper platform having a tee and target located forwardly of the tee; ball arranged at above for striking towards area, one end tether attached thereto, extending through slot in with other being secured to elastic bands anchored lower location rearwardly area; plurality bearings area supported on platform, so that engages least two bearings. The has sleeve thereto which is adapted engage surface thereby generate friction between when struck. combination provides significant braking forces slow down flight ball, control return subsequent shot. also various adjustments permit simulation shots lies ball.
