I always had a problem with whistles, explained referee Ron Foxcroft who, in 1987, built Fox 40 International, Inc. on the foundation of a single — better — whistle. Today, Fox 40 International, Inc. produces an extensive line of durable, finely crafted whistles and attachments, mouth guards, pro-coaching boards, and more. Explore the wide selection of Fox 40 products offered by the reliable sellers on eBay. Your team will never miss your calls again with a Fox 40 whistle. Select a classic whistle, available in a myriad of colors and with or without a cushioned mouth guard; a Sonik Blast whistle, marketed as the "most efficient whistle in its class" and able to be heard over the noise of thunderstorms and roaring engines; or a Sharx whistle, manufactured specifically for outdoor use and designed to perform well in all weather conditions. Keep track of your whistle with a Fox 40 lanyard, available in a variety of colors and styles including breakaway, clip, and wrist lanyards on eBay. End of problem.
