I've used the Xtream a few times. Works well, feels weird, costs too much.
 
What do I mean? I suggest you try a Posieden before you buy one. Be sure to take the reg out of your mouth and put it back and purge. Then you'll know what I mean.

You don't feel there is a significant difference between the Apeks and the Posieden? Ok. They both deliver lots of air shallow and deep. Check into annual servicing costs as well, and make sure that you have someone available to do the servicing. Not a lot of people service them.

Best of luck with your purchase.
 
I love them, I have 4 xtremes actually. They breathe like a dream, but do breathe very differnetly then most regs you are probably used too. So I would try before you buy, not everyone enjoys them. And the purge is something you have to get used to as well as learn to use gently, purging will clear your ears its so hard.
 
Poseidon regs are great regs, expensive to buy and service but very good. The do breath differently because they use a servo instead of a poppit valve. It takes some getting used to but they perform very well. I have both the Poseidon and an Apeks and given a choice I would buy another Apeks simply because they are cheaper and easier to service. Perfomance wise there really isn't a huge difference.
 
Lots of the service people were drivin out in the oo-04 time frame when parts were real expensive and hard to get. ( bad US reps) If you find a tech that made it thru those years then service is not even that expensive. Maybe the same as anything else. So, if you have a good service guy in your neighborhood go for it, great regs. I dive Cyklons and they make me a better diver.

Hello everyone, I dive with a Poseidon Extreme 90. I love the **thing. I also have the Cyclone, it’s the first Reg I ever owned; you can say I cut my teeth on that one. And still, it rides my pony most every dive. When I think of Poseidon Regulators, I think "tried and true." They’ve been around for a while, with an internationally good reputation in almost every weather and dive condition. You know, time-tested in the field like Range Rover, Mercedes, and John Deere. For me, I measure my dive experiences by how much fun I have. And “fun” is an interesting composite of safety, worry, and enlightenment. I take this formula, if you will, into places and conditions some may consider to be extreme or even dangerous. If I can go down my list of concerns and my Reg is consistently NOT on that list, I stay with that Reg or the upgrade unless the standards change or until I find something better. Addressing the matter of cost, I’m not a rich man; in fact, cost is one of those things always on my list. So I buy the best I can find, I buy it one time, and take good care of it. It should come w/a good warranty and/or service package. In short, if something goes wrong it’s not likely to be the Reg. Oh yeah, practice with your regulator; you will quickly learn to feather the purge button or it will blow a six-inch hole through the back of your head. Learn as much as you can about your reg. After all, it is your life support. Then, cross it off your list.

Poseidon's are great regs, I've owned 2 Jetstreams. I switched to Zeagles, partially because I like the breathe on the Zeagle better, and partially because in my area service on Poseidons was really hard to find, and cost an arm and a leg. Zeagles are easy to have serviced, and have a parts for life program. Like others have said, if you choose the Poseidon make damn sure you can get it serviced without a hassle and ask about annual service costs first.

I bought an old Cyklon 300 this year and had it serviced and am pleased with it except for what seems like when I am about fifteen feet deep I start getting water coming in. I usually just lean my head to the left so the exhaust tee is lower and that takes care of that, but is this common for these to breathe wet shallow? I had a Tekna 2100B and that really breathed wet. Also on my metal Cyklon 300 second stage after about half an hour into the dive the bigger mouthpiece I assume is the reason starts irritating my lower gums so by the time the dive is through I am relieved that the dive is over. I doubt the extra weight of the metal is causing the problem and somebody told me they are only about an ounce and a half over the plastic version. Is this jaw or gum fatigue on this old Cyklon normal too?
