Will Air Integration in dive computers replace the SPG?

Where is the popcorn when you need it?

Rebreather controlled / monitored wireless with a smartphone/tablet? No problem .... send a check

Where is the popcorn when you need it?...//...

It was taken out by a dear departed friend of mine. So was "Whine and Cheeze". W&C was replaced by "Thumbs Down".

Thumbs Down? So what, what's the diff?

Big diff: "Thumbs Down" can't be seen outside this community. W&C could. It all came down to an increasing legal threat from a dive op. She asked me to keep quiet about this, I did. Doesn't matter now. Miss her.

I love this thread, it is progressing on two levels and I defy any mod to untangle them. Maybe first read the "Logic of levels", van Vogt if you feel up to it...

Peace.

Let's see . . .I have a full 200bar tank and use 30bar in five minutes at 18m depth:

Five minutes elapsed time and my SPG should 170bar -check! It does. Another five minutes for total Ten minutes elapsed time and my SPG should read 140bar -check! It does. Fifteen minutes elapsed time and my SPG should read 110bar -check! It does. Twenty minutes elapsed time and my SPG should read 80bar -check! It does, and then start a multi-level ascent to the shallows & eventual safety stop. . .

Honestly people, you shouldn't need the function of AI to perform the simple subtraction operation above, especially after years of dive experience (and that's 35 years for you CT -Rich; and whatever other excuses you have for yourself Stuartv). . .

IMHO, you are starting to sound like a POV warrior, but I could be wrong.

I don't speak BAR. Well unless I have been drinking.

Ok, now that we cleared up my bar illiteracy... What's the difference if I do that on my wrist or my waist? In imperial of course.

Edit: Wait, I thought we just checked to see if the tank is full, half full or a little full. Not what the specific number was. And for some I guess it would be full, half empty or almost empty.

You don't even need to know this when you do a NDL dive.

You probably do speak bar. 1 bar is almost exactly the same as one atmosphere.
Using bar and meters is super easy. 1 bar pressure increase per 10m instead of 1 atmosphere or 14.5 psi per 33'.
You could get used to bar and meters in no time.
It's easier for finding out the capacity of our tanks too. A 12 liter tank at 200 bar (12x200) holds 2400 liters.
Maybe it's because I'm not used to the imperial system but it's seems really complicated to me.

Can you perform simple gas comsumption subtraction w/o a calculator AI?

You see, objective logic with decisive numbers will trump lame rhetoric everytime. . .

 

[Kevrumbo]

You don't even need to know this when you do a NDL dive.

You have to know your elapsed time gas consumption w/ comfirmed SPG reading for end of dive Rock Bottom Reserve indication or emergent conditions like leaks. How frequent you check on NDL dives depends on how deep & how much gas you have, especially on single tank.

US imperial is more confounding & cumbersome; Metric is easier & smarter to apply and as a frequent traveling overseas diver buddied with European & Asian Divers, you have to be competent using the world standard. (And working with unity/identity values like 1 bar/min per ATA, you don't need AI to perform the arithmetic of gas consumption).

I agree metric is better than imperial. I do use it for measuring liquids and some distances. I haven't sat down and worked out the conversions for diving other than the obvious, depth.

Nevertheless, fortunately for those who have WAI and are fluent with both systems, they can just press a button on their computer to switch to metric or imperial depending on what their buddy is using. No need to have two SPG's or try to read the smaller numbers on dominant/dual gauges.
