Disclosed is an apparatus and methods for a plurality of users to work
and/or play underwater with a supply of breathable air. The breathable
air is taken from the atmosphere above the surface of the water. The air
is sent to one or two submerged users. The apparatus and its components
are enclosed in a water resistant enclosure encapsulated by an inner tube
which floats on the surface of the water. The apparatus provides
breathable air to one or two users from a flexible air supply line, which
runs from the apparatus to each submerged user. The air pumps of the
apparatus push a constant flow of breathable air to each user. Each user
inhales air from the apparatus with a mouth piece that is connected to
the air supply line which is connected to the air pumps. Equipment such
as regulators, tanks or reservoirs are not needed. The apparatus is
powered by a dry cell battery and does not require fuel to operate.
