The term 'Acrobat Catchers' refers to a job that involves using NETS to catch acrobats. This job requires a great deal of skill and agility, as the acrobats must be caught in mid-air. The NETS used for this job are typically made of strong, lightweight material, such as nylon or polyester. The job also requires a good sense of timing, as the net must be thrown at just the right moment to ensure that the acrobat is caught safely.
