Abstract
Abstract A safety diving backpack, specifically a one-piece, detachable diving backpack, that may serve to dispose water-resistant handlights, life buoys, kettles and spin reel, complete with wires or ropes in the hollow cylinder and in the spaces as provided on both sides and on the underside thereof respectively. The linkage as provided by such wire-ropes to fellow divers allows divers to ask for help from such fellow divers in case of an emergency that befalls a diver equipped accordingly. In addition, by virtue of the striking marks and alarm signals of the headlights and life buoys released at the outbreak of fatal tides or other dangerous situations to the diver, the rescue teams can detect them in time so as to give necessary help to the endangered diver.
