Powerful enough to be heard from 1200 yards away, the Champion Sports 16 Watt Megaphone provides clear and effective long-distance communication for stadiums, team practice, and large crowds. Equipped with a shoulder strap and handheld microphone, this megaphone can be comfortably operated with one or two people. The adjustable volume control allows you to adapt to different crowds and distances, while the powerful siren is useful for when you need to get their attention.
