The whistles on the Coaches' Whistle Visa Gift Card honor this essential coaching tool. Team sport players learn at an early age that when they hear a whistle they are to stop, look and listen for what comes next from their coach. The common “pea whistle” was invented by Joseph Hudson in Birmingham, England, in 1883 in a competition sponsored by the local police to find a better way of attraction people’s attention. Hudson went on to become the world’s largest whistle manufacturer. Anyone who coaches at any level will love to get a Coaches' Whistle Visa Gift Card.
