HISTORY

Standard diving dress

From Wikipedia, the free encyclopedia

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 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 Standard diving dress has largely been superseded by lighter and more comfortable equipment.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 diving pump, a waterproofed canvas suit, a diving knife, and weights to counteract buoyancy, generally on the chest, back and shoes.[1] Later models were equipped with a diver's telephone for voice communications with the surface.
