Rubber weight belt with a folding marseillaise stainless steel buckle. Made from elastic material, the belt tightens automatically during diving, when it usually loosens due to abdominal pressure and the reduction of the thickness of the diving suit. Therefore, the belt always fits perfectly on the diver at every stage of the dive. The marseillaise stainless steel buckle features a control pin that tilts and enters the evenly spaced holes along the belt. Secure grip and quick release in case of emergency.
