'lo all...new to diving, just browsing around these tek forums since I'm really hoping to dive caves and wrecks someday.
That said, what is this DIRF, GUE, Tech1, Cave1, etc. I keep seeing people mention? What do they signify?
Also, hope this doesn't sound too dumb Why would you need certification to use a different gas for breathing? I see these Nitrox, Trimix, Advanced Trimix or whatever certifications...wouldn't the only thing you need to know would be bookwork, and how the different gases effect your body?
Thanks!
