Cricket nets are used by batters and bowlers to practice their cricketing techniques. They consist of a cricket pitch (natural or artificial) enclosed by netting on either side, behind, and optionally above. The bowling end is left open. Nets stop the cricket ball travelling across the field when the batter plays a shot. They save practice time and eliminate the need for fielders or a wicket-keeper. They allow more people to train at once, particularly when they have several lanes. They allow solitary batting practice when used with a bowling machine. Use Nets are fundamental to cricket practice and are used at every level of the game. Professional cricket clubs are likely to have over 10 lanes of nets, and be able to practice both indoors and outdoors. Nets are also very prevalent in educational establishments, as they allow safe and efficient training with a high volume of pupils when there are significant time constraints. Keen cricketers may have nets in their gardens. Nets helps safe practice. By containing most aerial cricket balls, they reduce the potential for injury of bystanders. However, the nets need an opening for the bowler, so it is still common for balls to leave the nets, and shouts of heads up are commonly heard. Types Indoor and outdoor cricket nets differ significantly. Indoor Indoor nets are often suspended on a track (runner) fixed to the ceiling of the sports hall or gymnasium no. The nets can drop 4–8 metres to the ground, and be over 20 metres long. Indoors nets are commonly multi-lane, with two- or four-lane nets being particularly common. Indoor nets tend to be white. They have separate 3-metre-high canvas screens that enclose the area immediately surrounding the batsman, for two reasons. First, the netting near the batsman has by far the highest work rate, and canvas is significantly more durable than mesh netting, so screens improves the nets' lifespan. Second, the batsman is less likely to be distracted. Indoor nets can be suspended on runners, providing a curtain system where they can be pulled in and out of use. This allows the sports facility to be flexible in its use. Outdoor Outdoor nets are the most common form of practice nets. They take many forms, with some being homemade whilst others are professional manufactured and installed. The design and construction of outdoor nets tends to be based around two factors: the frequency
