Poseidon vs. everybody else

[JT2]

I was just wondering why it is that almost every time I see a picture of a tech diver they are using Jetstream/Odins? I personally use a new Zeagle Flathead VI that I just bought after selling my ScubaPro Mk20/ G250's and I absolutely love it and can't imagine a reg that could breathe better, and I also have never heard anyone speak of the Poseidons during my short time as a Scuba Board member. What is the deal with the Poseidon regs, why do they, or did they have such a huge following in the tech dive community? We have one local guy who dives with a Jetstream/Odin, an when I ask him why he used it over other regs he simply stated that, " When I am just doing shallow rec dives I use Scuba Pro regs, but when you see me heading out with my Poseidons, I am going to do a deep dive, and at depth they have no equal, but in shallow water I don't like them." Does anyone know why he might make these claims?
Just curious?????????

The Poseidon Jetstream/Odin are used by many tech divers since they are considered to be very reliable regulators during any type of diving. The ease of breathing in a properly tuned Jetstream/Odin is in my opinion fenomenal.

They defenitely have their own characteristics, like a very strong airflow if you purge the regulator in your mouth (better hold on to your tonsils if you do not angle the second stage slightly). Some people have also complained about ice crystals down their throat when winter diving with the Jetstreams/Odins.
I worked as an instructor and sales person for a major dive store in Sweden, and decided to buy the Poseidon Jetstreams to give them an honest try. I did this since I heard so many different oppinions about their performance and characteristics.

I was diving Apeks prior to this, and it turned out I liked the Poseidons very much.
Today, I therefore dive both my Poseidons and Apeks regs, and am equally fond of both brands.

Sincerely

Poseidon was king of the deep water. Nowadays Apeks is considered to be best but many still believe in Poseidon. I dived an Odin for years and it never failed me. Maintenance is more expensive, parts harder to find, but it did breath nice in deep water.

My experience has been just like Globaldiver's. I use Apeks TX50 and Poseidon Odin/Jetstream and like both-perhaps the Poseidon a little more since it has minimal jaw fatigue.

...in shallow water I don't like them

An improperly tuned Jetstream can chatter in shallow water, proper adjustment eliminates that annoyance.

A Poseidon Cyklon was recently found laying on the bottom off the UK. It was rinsed out & found to be in working condition after being submerged for 2 years (the shop tracked down the owner through the serial number).
The critter only needed a plain annual service kit installed & it went back to work.
I've been using Cyklons for about 30 years in all sorts of nasty conditions and have nothing but praise for them.

Hi JT2

when you say "deep air dives" do you mean diving on the "usual" air beneath the 100 ft?
This is why many CMAS divers here in Europe like the poseidons! They like to dive deeper then 100 ft on AIR. This is, i think stupid!, NOT SAFE!. We know that diving with Trimix / Helium is the way to do it, at least if you want to do it safely.

As you know Trimix / Helium is far more lighter then AIR and this makes it breahte much easier and lighter and therfore you really dont need a so called "deep air or deep ocean or deep sea reg.".

I personally dont like Poseidons, besides as it is told
1--> they are very difficult in maintaince.
2--> There are very little technicians out there that can service a Poseidon at right way. An Apeks is a piece of cake compared to Poseidons!
3--> At the same time service quality of the company sucks. You have to wait for a long time if you send regs. back to the company.
4--> compared to an Apeks DS4 they are very expensive.
5--> Under water you cant open the second stage.
6--> I would like to quote GlobalDiver: "Some people have also complained about ice crystals down their throat when winter diving with the Jetstreams/Odins". My friend / buddy complains always about this matter.

You see we can buy here at the Netherlands an Apeks DS4-tx50 reg. at any time for 225us-dollars. A good poseidon still costs more.

These are the reasons that Apeks is becoming more and more popular these days among rec. and tech divers. By the way Poseidon is not the only company that makes this so called "deep sea or deep dive regs.". There is also a reg. that is called ABBYS, no i dont mean the Mares Abbys , that gives far more air then the Poseidons regs. do.

Anyway i would like to hear more comments on this one. Have fun with your dives.

Southern Scuba in South Ft Worth sells and has a great maintenance guy for Poseidon regs. If your interested drop him a line and talk to him about the regs. I can send you an E-mail and a phone number.

One of the reasons why the Abyss Explorers are so good is that they use a Poseidon first stage.

The 2nd stage is made by DSI, and is the same reg as used on their helmets & bandmasks.

It's nice using stuff that you know will work down past 1500'.:mean:

Hi BOB3

this is the modified version of the poseidon range(first stages) is it not?
By the way this is going beyond the limits of rec and tech diving! But nice though to mention it here. This is used for commercial diving is it not? I'll go check it out again, thanks for the input.

But i think Apeks is still the best reg. for rec and tec diving. By the way Apeks regs. are tested officially up to and over 1000 ft and they were STILL breathed very smoothly, and unofficially (read: not recorderd by official persons to verify this) up to and over 1300ft by a man that i forgot the name of right now. And he was very pleased by the design. By the way the guy had several regs. with mostly Poseidons. But after his dive he saied that he did like the Apeks range very much! Oh yes then there is another guy who try's his luck Leigh Cunningham who also uses Apeks and SP's. He dives mostly in the red sea.

All with all Apeks is nt desgined for commercial diving i think although they have a military range and maybe also a commercial range.... Anyone knows about this ?

And i wonder if a Big diaphragm (or a big second stage i mean) breathes well at 66ft when i am doing a regular rec. dive?

Anyway, can somebody tell what they excactly changed on Posseidon range to get a Abbysmal?



Have fun with diving,

hi JT2,

I been using poseidon for more than 5 years now.I use it in shallow dive, and deep dive. if you compare the part of the poseidon jetstream, on other parts of the reg. you will be amazed how simple,and easy to adjust the parts of jetstream reg.

we all know that when you buy a brand new regulator. you will notice on the first time you use it, it will start to free flow meaning that you need to adjust the second stage regulator so that it will not free flow or not that sensitive when the water pressure hit the purge.that apply to all kind of regulator.

the posiedon jetstream you need to adjust the second stage when you go shallow dive, and you need to adjust when you go deep dive. that is the big advantage of the jet stream, you dont need to open the entire second stage to adjust it. that you adjust it one time, and let the plus, and minus do the rest.

there is +, and - adjustment on the second stage reg.of the jet stream. + means that it will give you more flow of air, and - diliver less flow of air on a shallow dive. that's what we call D.F.C,(DYNAMIC FLOW CONTROL), and that's what I notice over a year, and years of research of other brand they end up using the same principle of the jetstream regulator the +, and - adjustment.

it's not only now that the tec diver using it, even before when the navy divers, and commercial diver using it because of the performance regarding air flow specially when you are working at depth. meaning that it's relialable. most of the tech diver dealing on a extreme environment, like caves, cavern,wreck, ice, or even just going deep.

theres are some advantage, and disadvantage of jetstream reg.

advantages:
- streamline, less drag while your swimming.
-bubbles, when you exhale bubbles not in front of you. it's good for photography.
-sharing air, you dont need to worry if it's up side down or not. cause the mouthpiece of the jet stream is poiting toward the divers mouth, and the hose is not twisted.
-second stage is so easy to adjust.
-maintenance, not that much. this what I do to my reg when rinsing it. before I disassemble. I purge while rinsing just to make sure that salt water is completly rinse. second stage, and the octo.

disadvantage:
parts? not that hard to find, you can even buy a complete kit on a very reasonable price.
