Standard diving dress

A standard diving dress consists of a copper, brass or bronze diving helmet, an umbilical cord leading to a surface supplied diving air pump, a canvas diving suit and lead boots.

This type of diving equipment is also known as hard-hat equipment. It was developed in 1819 Augustus Siebe. It was commonly used for commercial diving and naval diving until the 1960s when SCUBA equipment and saturation diving became more common.

As the diver walks on the sea bed, the diver must wear lead, generally on the chest and boots, to counteract the buoyancy of the helmet.
