Re: SUPERB article on deep air diving
While I understand his endorsement of deep air, Bret is careful to exclude most all conditions we as spearfishermen encounter on almost every dive. Kind of like endorsing "Buzzed" driving in the Nevada desert. Sure, most anyone could probably do fine to 200 fsw on air if you're just down there snapping photos, but start digging a shit shot carbo out of a ledge and things can start going south fast.
Rodeo spearfishing past 130' has enough dangers involved with it..... why choose to do it impaired?

Re: SUPERB article on deep air diving
Brett did a test with single al80 with some great time divers in the Bahama's and surprised them of test, a couple of them threw on what ever they found and put two 80's together. Brett wanted to see how deep on al 80 plus a narc factor. brett made it to 380 or 400 something it was along time ago, some narced out and ascended.
Brett more than likely spent years putting together that article for info on deep air diving as it has become popular again. I have been doing it for many decades and enjoy it, right along with tweaking my narc with a tad of helium. Forum boards have been debating it for over a decade now. Brett again has give to the dive community of great info and wisdom from all his experiences.

Re: SUPERB article on deep air diving
Just because something has been done or is "doable" for some doesn't make it smart or as safe as it could be. We don't call it "Rat Poison" for nothing.

Re: SUPERB article on deep air diving
Posted for informational purposes only. Not trying to tell anyone how to dive or not dive. Narcossis is obviously a very individual thing & is just one diving & spearfishing risk. Everyone has to evaluate all the risks of diving & spearfishing for themselves.

Re: SUPERB article on deep air diving
Steve, your your lead in is perfect "For those who dive deep air". It is a good artical and Bret knows more than most about it. He doen't mislead in his opinnion and states the constraints in theory accurately.
People get hurt and die on air and mix gas diving alike. Personally, I am not a fan of air when I can have a clear head when it counts. Please don't take my comments as a shot on you posting this..... It's a loaded topic anywhere it's discussed.

I personally don't get any noticeable narcossis. But my skinny ass DOES get cold easy. The tech guys tell me helium can really chill you down. That & the inconvenience/cost have kept me away from it. |

I imagine many similar tests have been conducted in subsequent years, but that is the one I remember. |

Re: SUPERB article on deep air diving
This is all comeing back around again due to cost of HE in the current market. That article and heated disscussions hopefully will educate, not advocate. As said above you really do not know how impaired you are till you you do the same dive with some HE for comparison, it is vivid.

Re: SUPERB article on deep air diving
Training is a big issue for most when it comes to complex mixes as well as computers and competent shops to provide the right prescription for what your diving. I can see where deep air is a simplistic option for most who are dabbling in depths beyond their certification and or training. Many just don't have the time, money or self-justification to pursue such endeavors. I can’t say I blame the majority, but I can testify that if you ever get used to diving 140+ on air, then make the same dive on trimix, you will repetitively kick yourself in the nuts for every dive you did without. It makes that much of a difference and I don’t care who you are or how long you dove on deep air.
