ture Jily24 but there are good scuba stories on the net too. My favorite site is the myscubastory site. They have shark diver attack videos, true scuba diving stories, lost buddy stories, dive accident stories and videos. Type myscubastory into google and its the first one
one man set a world record of 124 meters with no air tanks..just free diving, constant weight free diving, Herbert Nitsch (Austrian), -124 metres..wiki
Overseasmedia: how does this work? I know why you add helium and nitrogen but in this video it says that the mix contains only 5% oxygen. The body needs around a minimum of 16-18% to survive. How could one breathe only 5% and survive?
You can breathe 5% oxygen if the pressure is high enough. The PPO2 must be between 0.21 bar and 1.60 bar. Below 0.21 bar results in hypoxia and above 1.60 bar can result in CNS O2 Toxicity.
At 100 meters, the pressure is 11 bar, so the PP02 of this mix would be 0.55 bar, so it is breathable. If you were to breathe air at 100m, the PP02 level would be 2.31 bar, which is highly toxic, and the PPN2 level would be 8.69 bar, which would result in severe narcosis.
@StarQwest Im curious, could you use a trimix with 21% o2 and then a nitrogen, helium mix and do a recreational dive to 40m ? Any advice would be good
The air is thusly compressed so as to cause a greater amount of processing that can only be compensated with adding an additional and increasing amount of nontoxic gas.

hydrox theoretically allows you go to 500-700m (1,5000-2,000ft) dont know if people use it though since of its complex mixture and very flammable

i still dont have a clue what the HE2 is supposed to do
dont you need o2 for your body?
can you explain to some one without any diving experiance ore use of difficult words
cause my english sucks ass

I guess that bigger numbers can do no harm :))
