Description

In the early 20th century, the best equipment available for deep sea diving was the Mark V diving rig. US Navy personnel would complete perilous work under immense pressure with only an air supply line and rubber gaskets to keep them dry and breathing.

The 68 pound helmet was made of spun copper with four sealed glass viewports. In the back, two gooseneck pipes connected the diver, along with a telephone connection, to the ship far above. The complete deep-diving outfit weighed about 200 pounds or 90kg.

The 1905 helmet was improved in 1916, and again in 1939 (which added a mixed air system.) The Mark V remained unchanged in basic design and materials until it fell out of use in the early 1980’s.

(A vintage diving helmet made of copper and brass is prominently displayed, showcasing its intricate design and rugged surface. The helmet features a lattice window and a sturdy rope tied around its base, indicating its historical usage in deep-sea exploration.)
