How is your impact? With this Pure2Improve Impact Mat you have visual feedback on your impact. No guessing anymore due to the velvet turf. Swing with or without ball and check your impact to improve your swing. Preferred surface would be grass, the 4 "0" rings can be used to hold the mat steady by tees or ground pegs (tees and golfball are not included). Use your club to clear the markings, you can do this over and over again until you've got that perfect impact! Can be used by left and right-handed players.
