Technical Examples
A training golf ball apparatus designed to imitate the realistic feel, weight, acoustic and flight characteristic of a real (regulation standard) golf ball, to allow a golfer to practice the sport in a realistic way safely at home, includes a mechanized shuttlecock; a lightweight ball component and a magnetized tee. When arranged functionally, the device will perform as well as a standard golf ball; give accurate feedback on performance and promote realistic training in the home environment. The device is engineered in such a way to give the illusion that a lightweight golf ball is of standard weight when it is placed on a tee. For safety reason, the training golf ball apparatus changes aerodynamic properties once leaving the golf tee, and behaves as a lightweight, high aerodynamic drag object once airborne.
