Abstract
A diver's buoyancy compensator belt to be used with a diver's buoyancy compensator of the type that allows for increases and decreases of air to be provided thereto, depending upon the amount of buoyancy that is required. The buoyancy compensator belt has a first belt made of webbing for attachment to a buoyancy compensator and a backpack that in turn receives a tank connected thereto. The buoyancy compensator belt retains the buoyancy compensator around a diver's waist at distinct locations to allow for movement thereof which allows for the belt to expand and contract, due to the belt being made from an elastomeric material. The elastomeric material allows for a stretching and contraction of the belt, due to various pressure conditions and can be made of elastomeric foam having discrete cells therein. As the belt expands and contracts due to the discrete cells being pressurized at various depths, it compensates for the depth. This provides for overall control of the belt that is accommodated for at various depths so that the belt can expand and contract commensurately with wetsuits underlying the belt that are also made of foamed elastomeric cellular material.
