I was just wondering why one wouldn't just use Heliox instead of Tri-mix so that you could do away with nitrogen all together? Is it because of the cost of Helium since it would take more helium to do this, or are there other things such as deco procedure or something. I was reading a lot about Navy dive operations and noticed that they used both Heliox and Tri-mix, although it seems they only use the Heliox on reeeeeally deep dives where I am assuming even small amounts of nitrogen could cuse problems.
PS. I am not Tri-mix certified and I am not trying to gather information so that I can go out and try Heliox at 1500fsw, it is just something that I am curious about and I thought this thread would be a good place to ask the question. Thanks
