How do you signal air remaining?

[TeddyDiver]

Marek, actually as you have noticed there is. But in some remote and a bit isolated countries like in the US of A there just isn't interest in universal methods, not to any imported universal methods anyway .
We are going to see after 10-20 years the "universal" methods coming from China and there's nothing we can do about it :11:

So if someone flashes 2 fingers, what do they have? I know divers who can outlast me on a tank, and I know for a fact there are divers who can drain a tank by the time I'm down to 2000 psi. 1 finger = 100 psi leaves no room for confusion.

Once you have separate signals/movements for thousands and hundreds, you are adding potential confusion to the matter.

Just my opinion.

2000 psi = 2 fingers
1000 psi = 1 finger
100 or 200 psi = LOW ON AIR signal or SHARE AIR signal.
No confusion.

Oh, man, I'm just going to sit back and watch this.

[...] there just isn't interest in universal methods

6 fingers alone would be 60 bar.

60 bar would be a fist followed by one finger.

Yeah, it really seems standardized in the metric world, too!

You are so right Marek!

Just flash the guage. How hard is that? If its too short, get a longer hose. Your SPG is as much for your buddy as you.

That's fine for your buddy, but if you are with a group, say a drift, and it is the DM asking they're probably not close enough to see it and signaling makes sense. (Buddies close together good. Whole group that close not so good.)

To indicate 1270, I would show one finger up for "1" then two fingers up for "2" followed by two fingers held sideways to indicate "7" and then a "O" with my hand to indicate Zero.

What do you do for 8? I have used both the two hand and one hand method along with showing my SPG. Whatever works.

If you are diving with someone new you should decide ahead of time so there is no confusion.

Yet another convincing argument against group diving.

Marek: With all the boat diving I do, its insta-buddy city every weekend. No biggie - have a briefing, flash the gauge, end of story.

Hey Damsel - While I'm not a drift diving specialist like many of you, I just did get back from doing 17 of them in Belize. I did 6 last summer in Mexico. On all of these, the sign to the DM was when we got DOWN to 1500 (the "T" or 1/2.) When we got to 700, we were to head up.

At no time did I ever have to semaphore some hand jive to the DM, nor did anyone else in our group. Our group, once in the water, was all over the place. Never, not once did the DM insist in knowing the specific gas levels.

When my buddy gives me the Turn sign or the Thumb, I know how much gas he has left. Otherwise we just show eachother the SPG.
If the wetnotes come out, the dive is over.

Come to think of it: a fist followed by a thumb would signify "I'm into my reserve, I'm going to surface". :11:
