The recently developed Air-Tennis tennis practice wall is the ideal training partner for everyone, from beginners to experts. This product is a unique and absolutely unbeatable piece of training equipment for use in stationary or transportable mode. It comes in a bag and is easy to transport. To set it up, simply unfold it on the ground and roll it out. Use the bellows (supplied), then fill it with air – it just takes seconds. You can use the air pressure gage, also supplied, to check that the air pressure is at the right level, as this also affects the way the ball bounces back. There are also attachment straps on both sides for attaching the practice wall to our pairs of stands, fences, or sports hall walls. The ground protection sheet, also supplied, is simply attached to the rear side of the wall with hook and loop fastener. You can also empty it in seconds, simply by turning over the bellows. Players can play on both sides of the Air-Tennis practice wall. It has lines marked on it at the height of the net to guide the player. Tested by international trainers who rated it very highly.
