资源简介:
A water safety flotation device includes a buoyant body and a hollow core. The buoyant body has a length and a width, with the length defining a longitudinal axis of the device. The hollow core extends along the longitudinal axis of the body. The hollow core is substantially conical and provides a first opening in the body at a first end and a second opening in the body at a second end. The hollow core serves the function of a megaphone.
