Abstract
An individual flotation device includes a shell that has a cavity for receiving air and a housing that is connected to the shell. The housing has a metal air battery compartment that is dimensioned and configured to receive a metal air battery and also has an aperture. The housing may be located on the shell such that the aperture will generally remain above water during use of the flotation device. A membrane that may comprise hydrophobic properties may be located within the aperture of the housing.
