regulator choice

[Mobulai]

Big changes afoot for Poseidon USA.

The previous company in charge of training and distribution has lost their franchise. It is being taken on by Mark Derrick, the owner of DGX, who has formed a new company.
I have tentatively been asked to become their US military and civilian Service Technician trainer.

A new website, poseidondiving.us will make parts and kit distribution much easier, and per DGX conditions of participation, Poseidon will support training and sales beyond dive shops, and direct to the consumer.

I'm meeting with their Chief Trainer this week. It will take us some months to get this up to speed, but I would take issue with the "service quirks" urban myth. The new models are extraordinarily simple to service. They're just different.

The Poseidon Xstream first stage is among the best designs in the world. The second stages breathe differently - they don't "sip", but that's not a good way to breathe anyway. Sipping exchanges too much dead space gas in your airways. But there are those that like it, especially in deep water, and those who don't. Tomayto, tomahto.

For those who know me, you know that I won't just become a Poseidon fanboi. I'll continue to call things as I see them. But if this all pans out, I'm determined to put the rumors to rest, train anyone who wants to learn, and work with Mark on spare parts distribution. Poseidon Cyklon is a very old, proven design with omni-position capability without being hard to breathe (e.g., looking up). Poseidon Xstream has similarly excellent case geometry fault, and is as reliable as it gets. It is one of only two regulators certified by the USN as a cold water regulator to 190 feet.

Going forward, I'm sure there will be lots of discussion comparing the fine points.

All I hear is great news (for US users mostly)
Any chance we get a Poseidon service dedicated seminar/reg geeks as well?
Maybe it’s time we the EU users get our service parts from the US for a change

(i am typing this while taking a break from torturing my very 1st cyklon, I got no clue what I’m doing here; eg. I’m checking it on an mk17 I know it’s a no-no, but didn’t get to even open that 300 1st stage yet. send help)

I think they’re more or less the same height

Can’t speak for the mk25e (don’t have one)

The old mk19 is the only one that’s quite huge

It's the length from the DIN fitting to the 5th port that feels a lot longer on the Mk25 vs DST and doesn't route nicely.

Honestly if Poseidon made a reg witg a turret and possibly 5th port that would be interesting. Although I'm still not really a fan of their 2nds, at least the Jetstream.

It's still in the planning stage. Between moving my shop, selling a house, doing Seminars and now this, my plate's been too full to do another Reg Geeks. I've felt badly about that.
But one of these months. And I think a Mares session, too, eventually. My conversations with their Chief Engineer have been fascinating. There's so much thought that's gone into all these designs from all the manufacturers! Quite incredible, for such simple devices.

But yes. There will eventually be two shorter, Poseidon-specific courses for those starting from zero, and those who already have basic regulator training, to be able to service Poseidon regs. And unlike my long theory seminar, these will come with official Poseidon certificates. If it all pans out...

Oh I see

least the Jetstream.

I understand, just used one yesterday to force clean my daughters nose
That thing is intense

2025 looks exciting, Just don’t wear yourself out good doctor

well.. all in good time, look forward to it whenever it comes (here I’m calling a spot in your waitlist )

Mine night just need adjustments now that it's broken in a little but feels like trying to such through a straw, except for when first pressurizing or purging then it's unreal how much flow they have.
I do like being able to scooter inverted without breathing wet.

Honestly that all sounds like a huge positive. Always been curious to try a Poseidon reg, but the lack of support/fear of servicing issues has been a barrier for me. All signs point to looking hard at set of their regs in the future.

Well, there are lovers and haters.
But if you're a hater, pairing an Xstream first stage with your choice of second stage puts you ahead of a whole bunch of brands. Its S-pathway for high speed, high pressure gas flow is smoother than any other design. That, plus the ruby ball that acts as half of the valve means very stable long term performance. I immediately dumped my Apeks US4 on my JJ-CCR for an Xstream. More peace of mind.
Like most other brands, an end seal rather than a neck seal of the connecting bolt (DIN or Yoke) means that you still need regular service to keep that from locking up with verdigris corrosion. But if your gas pathway stays dry (i.e., being careful with tank changes on a boat trip) then the rest of the valve can go a long time before showing any IP drift.
A ball of one diameter nestling in a cup of a slightly larger diameter creates a hairline sealing line just like a knife edge, but without the change in flow vector that sandblasts other designs (incl. the earlier 2960/3960). See? I'm not averse to criticizing them when it's warranted. But at least replacing a scored 2960 valve piston is inexpensive.

I just love how this thread moved from comparison of 2 blunt edged pistons regs to teaching me about diaphragms and Poseidons (not complaining one bit)
