The electronic emergency rescue whistle is made of high quality ABS. It features a crack-resistant fish mouth and a powerful buzzer that produces a loud and consistent 125dB sound. Please do not twist the whitebait mouth, otherwise the whistle may not work. There are whistle lanyards to hang or attach to backpacks, life jackets, belts and shoulder straps. Built-in two button batteries.
