Why the dislike of air integrated computers?

[AfterDark]

I never saw a J-Valve on a regulator. I owned a few tanks with a J-valve and that's how I first started diving in 1969 with no SPG, no Depth Gauge and no BCD. It was simple to the point of being stupidly so and I'm ever so glad things have evolved.

Really? Healthways had a reg with a Jvalve on it. I think USD did also and then there was the SP MK 7 the honker, not a Jvalve but the same purpose.

I think the Healthways was the ScubaPro Scubair J. It was around the time that Healthways went under and their ScubaPro line continued.

Sportsways Waterlung, Aqua Lung Calypso J, and Sherwood 4000 could come with integrated J valve. There could be others. I haven't seen the 4000 in that configuration but the shop manual I was using to fix mine showed the parts diagram and where it would attach on the 4000.

Because of the expanding use of j-valves on tanks, the sales of regs with j-valves probably didn't amount to much. I've seen more about them looking at vintage equipment than I saw when diving back when they were built. It was probably a short lived fad.

Now your giving me flashbacks.

Really, surely you jest? The USD Calypso J was available for a number of years, I think into the 70s and it most definitely has a J valve, being as it was my first new purchased regulator bought with my money . I bought it because my instructor, an ex LA County and early NAUI instructor had one and recommended it to me. I think it was $99 (this being summer 1966). Well, I think it was that, I am pretty sure the hardware store I bought it at, I got the kid discount. USD was not the only one that made regulators with a J valve incorporated. The Calypso J was a balanced flow through piston design. My wife diving with it circa 1980 something, yes she has a spg, no there is not an octopus:

And about 30 years later:

On the little button gauges, they are about 1.0 inches diameter though there are some smaller. You can buy the spool adapter for use on an HP hose because as they are manufactured they are intended to screw directly into a regulator port. And they are I think brass and glass. I have a couple somewhere about. Since the primary instrument is the AI, this mechanical spg is only there to get you out of a pickle or to allow you to complete your dive normally should something happen to the AI. And as was pointed out they would be good for the initial setting up to check tank pressure and valve ON.

Why would I jest? I'm not saying they don't exist, but that I've never seen one. Still haven't. I doubt that many have or even care.

 

[The Kraken]

They're usually old farts: over fifty. Just like you and me.

I might be over fifty, but I AIN'T NO OLD FART !!!!!!

I notice that there's a lot of denial in this thread!

Bring back the DACOR Olympic (the model with the integral j-valve)!!!!!

The Calypso J was not a rare or obscure regulator. It, along with similar models from other companies were very popular and were top of the line, like buying a Legend today, I think manufactured between 66 and about 74. People give me this stuff sometimes. The 58 Pico Ave. California address Mistral, my first regulator, the 66 USD Calypso J my third regulator and first I bought (HP port on opposite side and notice there was only one LP port) and a couple of more. Oh, and notice they are complete with necklaces:

So now you have seen one. While I seriously doubt anything like this is ever manufactured again, the sonic type alarms could be useful even today for dark water diving/salvage or back up instead of an spg to an AI computer. I did a lot of dark water salvage while in college, even if I had a computer I would not have been able to see it much less the spg I probably did not have either. It is true, extrapolating your thought, that people do not care, about history, thus the lethargic progress of humankind.

Dark water, what if there was a Braille spg or even a computer, touch a button and it would count out the pressure perhaps by beeping once for every 500 psi?

there is a reason (be it very specific) that the USD Military Single Post Doubles Manifold still has a reserve.....

the factory may be old, but the products are quite fresh.
