Abstract
An air breathing power source is mounted in a water impervious housing with a hydrophobic membrane across an opening in its top surface. The housing is secured by flexible straps over a users shoulders so that it is normally carried across the users back, but floats up with the air breathing top surface above the water when the user enters water up to and above shoulder level.
