HOW IT WORKS: Old Diving Suit

14:39 diver's left shoulder copper washer is upside down

so cool

Must play Bioshock now

Just like captain Cutler

Very interesting video.

i dove this Mk5 set up…bear on the surface a dream under water . Primarily because unlike modern dive hats u dont turn the whole hat..just your head moves… still in use overseas in places where high currents demand a lot of weight…like a bridge gap .

Imagine the first time they tried to send someone into extreme depths with this diving suit. All they'd see when they reel up the diver is a mangled crunched up, smashed pop can looking human/suit.

15:40 well I’m glad at least they gave him an iPad to keep him entertained

The unnerving part of being down deep in one of these suits is that the pressure from the air being pumped into them is the only thing preventing you from being crushed to death. If your air line was cut there is a one-way valve in the helmet to keep the suit pressurized and gives you a few minutes to get out of the water but if that failed your body is literally pulverized and crush up into the helmet like a mass of jello. Nice thought huh? I recognize that due to the high water content of the human body it is almost non-compressible by water pressure so the only reason I can see that this happens must be due to the un-pressurized space inside the helmet.

I want one

Something which looks like it was used in the 1800's, was used until the 1980's? HUH? With all the modern diving apparatus (including rebreathers) available during the era in which this film was made (and even much earlier), why was such a (seemingly) antiquated method used?
