80cu Tank at 800 Feet ????

you could pee into some sort of a vaccum

No thanks! :shocked2:

Think you have trouble with your breathing rates with your package in old hoover at eight hunder feet ?

 

[Jax]

No thanks! :shocked2:

Now everyone is looking in my door!

Wow . . . would one be able to even use a catheter at those pressures?

Thankfully, I cannot speak to the catheter portion of that equation. I can personally attest that the remainder of the system functions in a hot water suit, at that depth, with no perceptible difference than at 3'.

So in a hot water suit I'm guessing you don't need a catheter...or p valve.

Peace,

Are you sure you want the answer to that? :w-t-f:

That's true perhaps... but I would discourage peeing into a fan.

Sorry, I figured everyone knew about them since DUI is so well known on this forum. Picture a loose fitting one-piece front-zip wetsuit with a valve and manifold on your right hip. A hose with a QD (Quick Disconnect) delivers 2½ gallons/minute of salt water at 110° F. A series of ¼" hoses with holes punched about every 4" distributes hot water down your limbs and around your torso. Hose ends dump hot water into both gloves, boots, and in a hood if you are wearing a full face mask instead of a hat. It is simply open circuit.

Hot Water Suits for commercial diving by DUI - Diving Unlimited International

Water is delivered from a boiler or heat exchanger at the surface and also heats the bell, if you are using one. The same hot water passes through a heat exchanger on the hat for the breathing gas, typically below 600'. A diver will loose core temperature on HeO2 below 600' even with a hot water suit due to respiratory heat loss -- Helium conducts heat about 8x faster than air. Divers without heated gas supplies will begin to develop pneumonia in as little as half an hour.

Modern saturation diving would not be possible without hot water suits. Drysuits aren't remotely rugged enough. I have worn holes in both knees of a new hot water suit in a couple of days -- it is just another place for all that hot water to leak out. The norm now is to wear heavy-duty coveralls on top of them to extend their life.

That is what put Dick Long/DUI on the map. It was a Scuba shop in La Mesa, California that also made custom wetsuits before. The Diving Unlimited Logo on all their suits was a heavy-gear/Hard-Hat diver sitting in a steaming bath tub. It became Diving Unlimited International as he sold more hot water suits and boilers all over the world, and then DUI as the recreational dry suit market developed.

Another thought on planning for deep dives came to mind last night. You must also account for, and carry, enough gas to equalize your drysuit.

If you are man enough to go to 800' you should be man enough to do it in a wetsuit. Or speedos. :cool2:

I don't know about you, but my manhood retreats when the hot water stops at 800' to the point it is obvious that they just don't want to be there anymore. The way I figure it; they usually win arguments with my brain anyway, so I follow suit.


Edit: Commercial diver are always being asked: "how cold is it down there?"

Answer: 110° at the injection point of the suit, who cares about the rest.
