The Teremax tennis training apparatus has been developed for training purposes for beginners and advanced tennis players. It is relatively simple in construction and can be dismantled easily and quickly for transportation. The training apparatus is provided with an electronic device which allows reaction training to be carried out as well as basic and special shots to be practised. The balls pass from a ball tube (see drawing) to the ball release opening. When the ball has been released, it drops vertically to the ground and, depending on the height-adjustment of the apparatus, bounces up from a defined point on the ground, from where it can then be hit. In a higher adjustment of the apparatus, the ball can likewise be hit directly in the air as a volley, smash or service. The apparatus can be adjusted to manual and automatic operation. <IMAGE>
