Poseidon 'Skinny'

[JDostal]

With that little plastic bushing...

It's easiest to take the reg apart to do this. It has got to be adjusted just right. The easiest way to do this is just rotate the bushing 90 degrees and test. If you get it wrong one way, you'll have your tonsils knocked out of your throat because the air flow is directed righ into your mouth. If you have it directed the wrong way the other way you'll barely be able to breath out of it.

By rotating the bushing 90 degrees and then testing, it should only take you a couple of tries to get the airflow pointed in the right direction.

The reason you never see it discussed is because apparently not a lot of people know about that little bushing. I was was speaking w/ my instructor/lds owner last night and I guess he has seen a lot of those regs come in w/ the owners complaining of bad breathing...turns out it's a quick bushing adjustment and it's all done.

And yeah - catching those things is like a hornet in a hurricane Once you tear one down and see how the air is let into the chamber you really see why. Talk about airflow!!!

I guess I'll just keep switching between 2nd stages while I dissasemble them and adjust underwater. In the past I would set the main to go a little positive. I may try to invent some kind of predive clip or something to prevent dropped second free flow. Cyclons are not 'sippin' regulators.

I don't have a free flow problem with my Cyklon-I do with my Odin. I am used to it and the gas loss is minimal.

It may have been that my LDS adjusted the Cyklon a little different(lowered the ISP) but it breathes fine.

I guess this thread is beat to death but I thought I'd just add a little more. Every group test that includes Poseidon (Odin or Cyclon) gives them low marks it seems. The machine tests indicate high levels of work or at least a very "strange" profile. Why then do I keep returning to my Cyclons (one 2nd stage nearly 30 yrs old). I have 2 Atomic B1T2's, 2 Oceanic Zeta's, A Zeagle setup (T50D), and some Aqua lung (used for deco and pony). Why do I keep coming back to the obsolete Cyclon? My sons keep going for them too, but I just figured it was because they looked so "cool". I just figured the wide range of opinion on these regs had to have something to do with how they are set up. I don't set my main to "blow my tonsils out" but I do set it so that it does go a little positive during a normal inhale. It's a little like being on a ventilator. During those early season dives when I'm not in the shape I'd like to be in I find my Poseidon's to be a comfort in the way they breathe. I must be crazy.....

There definitely doesn't seem to be a middle ground on people's opinions with these regulators. You either love them or hate them. I just know that after having used a bunch of different regulators I finally got the chance to use a Poseidon...and I was forever converted. Especially after you see how the Odin is designed compared to a lot of other regulators - it's a very unique design that is very hard to have it fail.

I dove with a tech diver this past weekend whom had 2 Poseidon's. He loves them. He has both the Odin and the Cyklon's and likes both over everything else he has tried. He did attest to them being slightly 'positive pressure' breathing but says he likes that especially on dives where he's doing physical work (he does underwater boat and lock repairs, etc).

 

[JDostal]

Yeah, I like the positive pressure on them. It's not like it's forcing the air down your throat, it's just very, very reassuring to me. It's just nice, on a deeper dive or a dive when you are working, to really, really have air when you breathe in. I'm a fan.

 

[ScoobieDooo]

Yea,
thats what he said...when he NEEDS extra air, its right there delivering it - and easily w/o requiring a lot of effort to suck it in.

He buys he's from a Canadian shop as rebuilds that others trade in, so he gets them at great prices, and, they are in 'like new' condition. Metal or plastic body Cyklon's as well.

I own apeks,Scuba Pro, and Poseidon.

my Mk20 D400 is my chosen primary
my mk25 550 is around my neck

I have had all of them below 200'

all would do the job

and I have never paid for a part from Scuba Pro

I have never had a problem with Cold water
and I was diving in MN, WS for a year

I prefer the D400 deep
it is like a race car it opens up below 130

Bob3,

Poseidon retail prices
The suggested MSRP for the Poseidons are:

Cyklon: $475

Jetstream/Odin: $460

Xstream: $555

Poseidon doesn't require their dealers to maintain fixed minimum pricing, they are free to discount.




ALL MSRP are high - not just Poseidon. My LDS sells SP at MSRP - and they are just (if not more) expensive than the Poseidon's are.
