Abstract: A device for allowing an athlete to practice various methods of propelling a projectile in a controlled and accurate manner by allowing him/her to place the projectile on a specific location on a target. This device uses hook and loop fastening material on the projectile and the target to allow the athlete to know where the projectile strikes the target and allow him/her to practice various ways of getting the projectile onto the target. The reversible nature of the target allows the athlete to practice different sports using the same apparatus or to practice skills required in different situations encountered in the same sport.
