Abstract: A system for retrieval of objects submerged and lost in water is disclosed. The system comprises a gas release cartridge, an activation assembly arranged for activation of the gas release cartridge in response to at least one of: lapse of time, pressure, trigger-wire, indirect water contact, or remote acoustic command or any combination thereof, components of which are all contained in an inflatable bladder. A guide line, one end thereof attached to the bladder and the other end connectable to the object, is housed inside a non-watertight casing together with the inflatable bladder.
