This is why the Rule of Thirds was invented. Had you turned the dive with two cubic feet of air remaining, you would have been fine.

I travel. So I would say that some traveling divers make these choices. But they aren't prerequisites. The word "prerequisite" suggests some force of the Universe outside of our personal choices. So again I would word it that some travelling divers make choices thyat lead them to believe that...

I don't know who "they" are. I'm personally fine with this, as long as we are clear about the matter of choosing to use it and being specific about which circumstances are the "right" ones. Then again, given my experience, I'm obviously a :dork2: :popcorn:

No, the argument is not whether X or Y is a "Useful Tool," the argument is given a set of options, which is the best option for a given diver. Or to rephrase it, under which circumstances is SpareAir the best choice for a diver? My point is that it is the best choice for a diver when he chooses...

Their web site lists many of these special dives and explicitly states that many of these dives only permit one or two clients. This suggests that they do have an extremely low client to guide ratio on certain dives.

Let me see if I understand the argument for SpareAir so I will know whether to buy one for myself. A SpareAir is "Better than Nothing" for me provided that: I refuse to go to the trouble of purchasing or renting fully redundant gas equipment such as doubles; I refuse to purchase and carry a...

I must admit that the thought of diving to 225' on air using a single AL80 seems a little surrealistic to me. If someone described it to me as an "advanced" dive for any operation I'd have thought they were making things up. Maybe, maybe not. I look forward to hearing what the operator has to...

Do you have the option of diving doubles and/or access to EAN50 or EAN100 for deco?

It's a forum, sometimes people make stuff up. Call or email if you want the truth. ;)

Gosh, for a moment I thought you wrote "speculum is what happens," and it really did feel like we were planning an expedition to The Little Frenchman's Blue Hole. :shocked2:

Nevertheless, there is no reason to bet or guess. If you are concerned about their practices, you can call or email them and they will tell you exactly how they conduct their dives to 225 feet. Why speculate and try to glean hints from incomplete information? I suspect we all agree that...

Did you see the post that read (in part): "Carry AL80s" may mean singles, manifolded doubles, independent doubles, or side mount. "Extra gas" may mean anything from guests diving singles with DMs diving doubles up to and including guests diving doubles with stages. "Stage bottles" suggests...

I'm fairly new to this, but so far my little experience has been that I never need to touch the inflator when ascending. In fact, I think I could disconnect it with confidence and orally inflate at the surface if need be. So far, what I do is let out some gas, then use my lungs and/or swim up to...

Well, don't forget that you are probably now talking about redundant back gas and deco bottles, along with all the failure modes they imply. So we are talking about quite a bit more training and expense. I may get there eventually but this seemed like a useful step at the time.

To clarify, the class I took addressed the use of mixes with a maximum PO2 of 1.4. I was calling that hyPERoxic because it was > 21%, like 25/25. My understanding is ghat hypoxic would only apply at much deeper depths, which would be outside that training by a long shot. Am I using the wong term?

Ok, I'll bite, NVM means... ? And sir/madam, would you care for milk, sugar, or cream in your coffee? :coffee:

I actually got it specifically to use on a return to the Forest City (135' to the stern rail), but by the time my vacation rolled around I didn't feel the rest of my skills were in place so I didn't do any deep cold water diving. I've also heard this type of mix has applications for shallow...

I'd like to get people's full-on opinions about diving hyperoxic trimix on dives that are within NDL/Minimum Deco limits. I know we have a good time arguing about labels, so feel free to discuss what you think this should be called, up to and including stroke-tastic or dumb. A few agencies...

Well, I don't think they were planning to ascend at 10 feet per minute or spend eight minutes on shallow stops. Do you want to try another run, this one assuming an ascent at 30 feet per minute and a five minute stop at 15'? It may not be to your taste, but you can at least get an idea of what...
