ABSTRACT OF THE DISCLOSURE A retriever device for locating a submerged object comprises a base member axially threaded with left hand threads, a spool positionable upon the base member and internally axially threaded with left hand threads, a screw member having contiguous right and left hand threads and holding the spool and the base member in secure position against the object, a retaining member mounted on the base member and including a transverse partition with an axial opening, a float member secured to the retaining member by a water-soluble adhesive means, and including attachment means for a line, and a line attached to the float to secure the float to the spool, and passing through the axial opening of the retaining member in order to be windable around the spool. Such retriever device is also intended to include a gas-generating tablet positionable upon the flat upper surface of the partition of the retain- ing member. The retaining member is intended to include a passageway fillable with water-soluble material which will, after being submerged in water for a while, dissolve and permit water to enter the internal portion of the device to react with the chemical and assist in separating the float member from the base member.
