Abstract: 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.
