A weight belt comprises a sheet of flexible material having two strips of material over one face and joined by stitching seams to form a number of pockets side-by-side, the pockets containing plates of lead, and being closed by further folding of the sheet to bring the pockets face to face, where they are retained by touch-and-hold material. They can be lifted away for adding or reducing the number of lead plates. Access to some of the plates can be provided to allow removal or replacement without necessarily removing the belt.

A weight belt for use by divers is formed at least partially from a phosphorescent material so that it will be easily visible in a low light environment. The belt may be constructed from a conventional fabric web over which slotted weights are received. The weights may be painted with a phosphorescent paint, or may be encapsulated in a plastic material impregnated with a phosphorescent substance. Alternatively, the diving belt may be formed from a plastic material impregnated with a phosphorescent substance. The slotted weights are slipped over the plastic diving belt and maintain their adjusted position due to frictional engagement of the belt with the slotted weights. The diving belt, when in use, will glow in the dark due to the phosphorescent material, thus enabling divers to locate each other and also preventing loss of the weight belt.

A diving weight for scuba and other divers particularly designed to hold the weight in conformance to the diver's body and including a surface finish to prevent or substantially eliminate marring and scratching of the same. Belt receiving slots are provided along the length of the weight with a spacing formulation to hold the weight and maintain the attachment belt in close conformance to the user's body. The slots and weight are designed to allow the belt to pass from a recessed interior surface thereof about a recessed portion of the exterior surface and back to the interior thereof to hold the weight close to the user's body. The interior and exterior recesses of the weight allow for close conformity of the belt to the weight and the weight to the user's body. The weight is shaped with a radius on all mating surfaces to facilitate dipping and coating of the weight with a vinyl material. The vinyl material provides and is selected to provide a matte finish to the entire exterior surfaces of the weight, including the slot surfaces. The matte finish substantially eliminates the appearance disfiguration as compared to smoothly coated weights.

A form fitting, flexible, multi-element device to be used as a weight to be attached to a geophysical cable. Said device is constructed of a plurality of molded and contoured lead inserts suitable placed inside of heat shrinking tubing such that after shrinking the finished product adheres to the normal parameters of the geophysical cable. Said device is attached to the geophysical cable by means of a locking band or strap.

An improved scuba weight having a hex-nut locking device molded into the weight is described. The hex-nut locking device secures the weight to a diver's belt, but can be easily loosened, permitting the casting off of the weight, including in underwater operations, if desired.
