A neutral buoyancy recovery device (NBRD) for retrieving an immobile object or incapacitated individual from a liquid area which utilizes neutral buoyancy to assist a rescuer. The NBRD is easily submerged under the surface of the liquid and placed under an object to be recovered. At least one bladder attached to the NBRD is inflated to create positive buoyancy and propel the object to the liquid surface. The bladder(s) is located in a space between two panels, which are connected to form one unit. The bladder(s) inflated manually or by using compressed gas canisters. Various straps and ropes are used to stabilize the object or individual as the NBRD is maneuvered through the surface of the liquid.

1. A device, having a length, a width and a depth, to aid in extricating specified loads from a liquid, comprising:at least a first and second panel, said first panel juxtaposed above said second panel, wherein said first and second panels define the device's length, width, and depth; a mechanism affixing said first panel to said second panel, wherein said first and second panels are affixed in a manner establishing an opening between said first and second panels to allow for ingress and egress of the liquid through the opening of said device and wherein said first and second panels are reinforced by said mechanism in meeting the specified loads for said device; and at least one object suitable for inflation with gas, wherein said object is placed in the opening between said first and second panels and wherein said device is neutrally buoyant prior to inflation of said at least one object and said device achieves positive buoyancy upon inflation of said at least one object.
