ABSTRACT:
In a lift device used by divers to bring objects from the bottom to the top of a body of water, this invention eliminates the need for a second bag. This is accomplished by combining the lifting and the carrying bag into one unit. The bags are combined in such a manner as to allow easy upright top loading, and to allow the bag to float while loading. It also allows for easy loading and dumping. The strapping devise connecting the bags at the bottom keeps the bags in a relative position to each other allowing the unit to float upright at any level, whether on the bottom or the surface of the water.
