Used for both shallow-water and deep-water diving. Early examples from the 19th century were commonly made of metal and featured several portholes for viewing, covering the entire head. Contemporary helmets are made of various materials (metal, plastic, fiberglass, etc.) and provide a single transparent viewer to aid sight.  ]]></dc:description></metadata>
