Self Contained Diving by René Bussoz

item ever made?

Hey, there is another air mangement system.

The LOOOONNGGGG hose of endless air.
Actually there are a few things that can cause it to stop delivering air but the guy on the other end is working hard to keep the air flowing knowing that some wet guy is likely to be real cranky if it stops.
Being dragged out by the hose is a strong indication of a 'problem'.


Did I say that?

a note about SPG's

When a spg goes bad (analog type) they usually loose accuracy at the lower pressures. The mechanism inside becomes stretched out or stickey and gives eroneous readings at lower pressures. I personally had a very well made spg that worked wonderfully for many years and continued to work wonderfully with a full tank but would get iffy at 500 lbs. of gas.

Until the tank was down to nearly empty the guage wouldn't move below 500lbs.

And while yes you really shouldn't be underwater with a tank at 500 lbs. the equipment should still work properly if you do...
