    It;s called SNUBA, instead of Scuba.

    Air is supplied from a boat on the surface with an air pump, down through a hose and into the mask. Sometimes it goes into just a mouthpiece (regulator) and the person wears their own mask for their eyes/nose instead.

    Scuba diving is wayyyy better... try getting a class!

    Hookah diving. There is an air compressor on the surface that pumps the air down to the mask. It is limited to about 30-40 feet. Get below that and the issue of the bends comes up. Same idea as a hard hat diving suit except you swim around instead of sink to the bottom.

    Don’t you read the Punisher War Journal. There are now tankless scuba gear. It uses something that can convert carbon dioxide into oxygen so the diver just breathes in recycled air.

      A "Rebreather" uses a chemical pack to absorb CO2, plus a small oxygen cylinder to replenish the used oxygen.

    They need the air pressure in the mask to match the water pressure of the water pressing on their lungs. The tank has to do that too. I imagine it's tricky to keep the water pressure just right, so they can breathe but not blow up and pop like a balloon.

    Air is supplied through the Hose up to a boat on the surface with an air pump.

    the 'tube' goes all the to the surface where it's hooked to an air compressor .............
