Abstract
A salvaging device, particularly for a personal device such as a smartphone dropped into a body of water. A housing has an opening and a gas cartridge. A triggering mechanism is further packed within the housing, which includes a lever arm. A main spring is above the lever arm cocking the lever arm in a downward position. A plunger is aligned with the gas cartridge. A water-soluble retainer abuts the lever, wherein upon the retainer dissolving in a water environment, the main spring recoils to thereby unload the plunger into the gas cartridge such that gas can exit the opening. A balloon is connected at the opening inflatable by the gas to thereby provide a buoyancy force to the handheld device upon inflation.
