  • A diving bell, also known as a wet bell, is a cable-suspended airtight chamber, open at the bottom, that is lowered underwater to operate as a base or a means of transport for a small number of divers. The pressure of the water keeps the air trapped inside the bell. They were the first type of diving chamber. Unlike a submarine the diving bell is not designed to move under the control of its occupants, nor to operate independently of its tether.
