What is the primary purpose of using whistle signals in archery?

The primary purpose of using whistle signals in archery is to provide a clear communication method. Whistle signals are essential for ensuring that all archers and officials on the field can understand when to begin shooting, when to stop, and when it's safe to approach the target, even in noisy environments. This standardized method of communication helps maintain safety and organization during practice and competitions. By using distinct signals—such as a series of short whistles to signal archers to approach the line and a long blast to indicate that they should stop shooting—everyone involved has a clear understanding of what actions to take at any given time, which is vital in a sport that requires focus and precision. This system enhances safety and helps to streamline the overall flow of the event.
