Surface supplied air (SSA) as a means of diving is one of the oldest methods of diving. Centuries ago, men operating hand pumps supplied air to divers working underwater. The deep sea diver with hoses for air and communication is known to anyone that watches WWII movies with the Navy being featured. In 1904, the US Navy adopted a hard hat deep diving suit that they used until the late 1980s. In the late 1960s, a system was designed that brought surface supplied air to recreational user.
