Poseidon Cyklon regulators

[Mobulai]

There are very thin cable or zip ties that will fit in the groove of that cap; but I wouldn't suggest any of the standard sizes . . .

I think I got some of the baby sized Ty-rap that would fit, I’ll give it a shot whenever I find the capacity to service that 2305
Skol!

What was the main difference when they upgraded from the 300/Super to the 5000? Just the balancing?

Yeah, the balanced housing -- but I never noticed any appreciable difference in breathing effort with either; though the cynic in me looked to those more expensive service kits with far more parts which required annual or -- nowadays -- biannual replacement, than the old 300 series, which had nylon gaskets in lieu of port o-rings which could last years -- and only three actual wear and tear nitrile o-rings, as opposed to about twelve in the other kit.

Below are the schematics for both the 2805 (300) and the 3891 (2962,3257, etc) balanced first stage service kits -- see for yourself . . .

That’s interesting. I would like to try them side by side and see how it feels to me. Do you know what is different with the Cyklon X? The reg for that is a slightly different part number from the Xstream one. Must have a different IP? Not sure that’s the right term.

It is the very same second stage paired with an Xstream first, and cranked to around 11.5 bar, from its typical 8.5 IP setting with the Jetstream and Xstream, and nearly impossible to freeze-up — without any added environmental sealing, such as caps and alcohol / glycerin concoctions. The first time that we tested it out, in Nanaimo, BC, was a bit nerve wracking, considering how unprotected the regulator initially appeared; but it worked like a trooper in the 6˚ C water, all while huffing and puffing in the heavy current, even with a bit of ice on its cap.

We tried that years ago, long before the advent of the X, and were pleasantly
surprised at how smoothly it functioned . . .

Hopefully it has not been discussed too often, I really searched and the lack of info makes me more curious.

Mate welcome the place is yours get on in here and ask whatever you like whenever you like enjoy

They're great classic regs you've scored cool, skol

I can’t wait to dive them. I shipped them off to silent explorers for a check.

Yes that big exposed spring looks like it will freeze solid in no time. The text says they can hold a purge for 10 minutes without freezing?!

If you mean the Xstream 1st stage, the spring being exposed like that results in water flow for heat exchange, which is in fact why it does not freeze.

Looks pretty I’d say

I have used Poseidon regulators since the 1970s -- the Odin (Jetstream); the Cyklons; and the XStreams (that fully-functional ice block, seen above), at temperatures well below forty degrees; and, in fact, have gone ice diving with all of them, at one to time or another.

On the XStream, which is about the simplest to service:


The Swedes do know something about cold water; though, it must be made clear, that any regulator can freeze if utilized improperly, under frigid conditions . . .
