Standard diving dress (also known as hard-hat or copper hat equipment, or heavy gear) is a type of diving suit that was formerly used for all relatively deep underwater work that required more than breath-hold duration, which included marine salvage, civil engineering, pearl shell diving and other commercial diving work, and similar naval diving applications. Standard diving dress has largely been superseded by lighter and more comfortable equipment. Standard diving dress consists of a diving helmet made from copper and brass or bronze, an air hose from a surface-supplied manually operated PUMP or low pressure breathing air compressor, a waterproofed canvas suit, a diving knife, and weights to counteract buoyancy, generally on the chest, back and shoes. Later models were equipped with a diver's telephone for voice communications with the surface.Hand operated divers air pump for one or two diversdiving, air pump

The Yokohama Diving Company was established in the early 20th century. Their helmets were initially inspired by the english Siebe Gorman helmets which they manufactured in a smaller size. This also resulted in a smaller volume helmet allowing the divers to use less lead weights when diving. In the early nineteen sixties Yokohama became involved in manufacturing their own helmets but in a different design after american diving equipment manufacturer Robert Kirby had rebuilt several Yokohama helmets into a more practical / modern design.
