I think finning/kicking "up/down" uses too much calf. If you press against the water similar to how you press against a bicycle peddle when you stand out of the seat (mountain biking uphill for instance). That motion works very well to get a LOT of power into your fin without the "kicking" that...

How did you find this document? Just a google search? If so what were your keywords? This document looks both extremely specific but also extremely on-point to what I wanted to follow-up on.

Let's just not over-inflate what I originally stated, because I agree with you at large, and in principle. But I'm also a stickler for logic :) All I was and will stand-by is that communication cannot in-of-itself determine competency. That has nothing to do with requirements of law, or...

It's an example that goes right over your head. It's irrelevant if they speak only German, they could speak gibberish. And you could be asking them in Counter-gibberish "can you turn a wrench?" And they can be unable to effectively communicate to you AND STILL TURN THE WRENCH. It is therefore...

The Navy Diving Manual specifies that: The problem with this statement is it isn't clear. Is 10% at 1atm normal for air? Or much higher than air and representative of Heliox? I just wanted to see if I can find a secondary source that confirms the Navy statement, but haven't found one. Or...

If someone only speaks only German, then the requirement to communicate a skill in English is illogical. But to generalize this statement I later change the terms to vernacular and nautical terms. Which gets the point across sufficiently.

Apparently though the Aspergillus are common and the death is a fluke. But, for something that's non-essential, better be safe than sorry :)

I'm only commenting on the logic used, but your experience may be completely sound and reasonable. Whether or not someone learns the language of the trade probably is a good indicator of whether or not they learn the trade at all. But logically, whether a person can effectively communicate is...

Thanks for this, when I use a question mark it's a legitimate question, not just me implying it's a good idea. So thanks for providing good feed back :) An edit, while the risk seems low, it looks like the method is sound. So given the risk (that fungus), just test your BCD by inflating, but...

There is an underwater perspective here, eventually, but first some background and why this thread. I'm fascinated with certain things and it has led me to a conclusion the world is about to enter a much more dangerous Cold War than the previous one. It will be more dangerous because the...

I also think I'm nitpicking in this case, but we get to nitpick and then choose what's worth acting upon, based on our accepted tolerance of risk, and our experience. But experience can betray us, and our risk tolerance may impede our experiences, so it's all a personal comfort level thing, at...

Can You Mix Alcohol and Sudafed? That's because Sudafed itself is an "upper" and uppers and downers tend to cancel each other out. Cocaine will make a drunk man sober. But, they have off-chances of strange happenings, straight-up heart attack being one of them. Sooooo, generally, healthy...

If you have to deflate BCD on ascent, might as well deflate it into your lungs?

Sudafed, Pseudoephedrine, is contraindicated at 100+feet where the effects of nitrogen narcosis will enhance the effects of Sudafed or alcohol, or both Any meds that are contraindicated with alcohol should probably not be used below 90fsw or whatever you think is safest because the narcotic...

You can do everything they can do, recreational, they just got a job to do :)

How are they using the green dye? For identifying differential pressure?

Are traction splints even on boats? That would be the biggest one to have available. Simple enough a monkey can use it, but probably going to be the single biggest stopper of loss of blood as far as bone breaks go.

This kind of gimmickry is not wrong, legally, but logically it's completely flawed. A German can be an excellent sailor and not speak a lick of English, but if you insist they speak only English, they will appear incompetent to you by your methodology regardless of the facts. While industry...

I didnt catch that. This is why I like these discussions. Good observations and thought gaming comes up and allows for critical learning :) At this point, a diverging discussion on data vs intuition and the advent of science, was spun off to this thread in the Pub: Data vs. Intuition in making...

I have to go unfortunately, and can't word something write at this time, but would like to continue this conversation later. To run through your hypothetical a brief bit, I know that I have to sacrifice 300psi for BCD, and I know that at an average depth of 60fsw it'll be a solid 10psi per...
