1. An apparatus for underwater retrieval of a magnetically-attractable object, the apparatus comprising:
at least one housing having an upper surface, side surfaces, and a lower surface, each of the surfaces exposed to an outside environment, the at least one housing further including at least two spaced attachment portions; at least one magnet disposed within the at least one housing,. wherein the at least one housing completely encloses the at least one magnet; and at least one line extending from the two spaced attachment portions of the at least one housing, the at least one line defining two opposing free ends, each free end spaced from one of the attachment portions, the at least one line between the attachment portions and the free ends enabling two users to hold one of the free ends with the housing located between the two users for underwater retrieval of magnetically-attractable objects between the users, and the upper surface, side surfaces, and lower surface of the at least one housing enhancing a magnetic field produced by the magnets to support formation of a magnetic field beyond the housing and to increase magnetic attractive force between the housing and the magnetically-attractable object during underwater retrieval of the magnetically-attractable object. |
