I have a cyclon 5000, The first stage is set at 145psi (so all my seconds are basically interchangeable) and the 2nd was adjusted to match it. It breathes perfectly and I have used it deeper than 200 in this configuration.
I use my cyclon as my primary reg or an abysmal reg (poseidon 1st Kirby morgan second) and an apeks as a backup, comparing the two at depth the poseidon just breathes better. The Absymal breathes better than both but I like the "feel" of the Cyclon better.
Contrary to the outdated info on APEKS site the deep OC record dives (1010 ft) were done on a ABYSMAL reg (the previous dives were done on the Apeks (less than 900 ft).
I'm not trying to insult you with the next question, but I'm covering all points..
Did you adjust the 2nd stage?? You need an inline tool to adjust the 2nd while the unit is pressurized or you'll never get it to breathe right..
Don't worry, describing your regs and offering a suggestion will not insult me.
Neither will it change my mind about Poseidons when you say you were able to tune your Cyklon to breathe well when the IP is set 35 PSI below factory-recommended settings. If anything it makes my point. If I read your note correctly about needing an "inline tool" to adjust the 2nd or "you'll never get it to breathe right," that appears to confirm that you also understand that either these regs are touchy and/or your workaround is.
If you already own Poseidons and you love them and they work for you, then good for you, dive on. But just because you were able to adjust the IP and the 2nd with skill and just the right tool doesn't mean the Poseidon is on my short list of regs appropriate for tech or rec. Or that they should be on any new tech or rec diver's short list.
There is a good choice of regs out there that are great for rec & tech diving and give as good a gas volume on demand at depth _without_ tweaking and finding kludgey workarounds to make them more compatible with the IP of other regs. So why would any diver buy a Poseidon when there are more compatible, more dependable, simpler, easier to get serviced anywhere and less touchy regs to buy unless there's some obnoxious guy online who's fed up with his and would sell them at a good price?
Which, BTW, I'm still waiting for someone to follow-through with an offer on! C'mon, Poseidon Odin and Poseidon Cyklon 5000 lovers, I'd never try to talk you out of yours and I'd rather sell these to ya'll than to some unsuspecting newbie! They're in good shape and I am pretty sure I have a long hose somewhere for one of them that I'll toss in!
C'mon, make me an offer I can't refuse (and no horse-heads, please).
