I have Poseidon Jetstream and 2 Odins. I absoutely love them!
One of the big pluses is that it has a side exaust, which I like. No more bubbles that go up on my face. It also delievers great air in any depth, it breathes the same 5 feet deep and 100 feet deep (I havent gone deeper than 100' yet).
Servicing - it can be pricy, but there are a lot of places that you can mail it to be serviced.
I'm pretty much sold on poseidon's. I got mine used, and had them serviced - the total came well below the price of a new one.

I have a Jetstream. I disagree that it breaths the same at 5ft as 100ft. Its a good deep reg but breathing at shallow really sux. For shallow diving (20m and above) I will much prefer my Mares Proton Ice. At depth (20m and below), the jetstream breathes excellent.
I have not tried out the Xstream yet. Maybe that reg will breathe the same at 5ft and at 100ft.
Servicing Poseidon is around 30%-50% more expensive than my Mares.

Is that really a plus? As far as I'm concerned I would prefer to have some resistance so I don't use my air as quickly.sbushong:
Doesn't actually work that way. If anything high work of breathing will cause mild stress which will increase your air consumption.AJ Tudor:
Had a Jetsteam - sold it after a few months.
Fantastic breathing reg at depth - someone mentioned 20 m - I would say below 30 m but just my opinion and may have something to do with fine tuning the reg. My reg was new from the factory and had factory settings. I found it a hard breathing reg in shallower water compared to the Apeks and Zeagle regs I have used/owned since - most dive time is spent in shallower water and the Apeks and Zeagle work well in deeper water anyway.
The dive / predive switch is useflul - with this reg a free flow can dump a lot of air in a very short time.
Bubble interference was not an issue for me - apart from breathing characteristics I quite liked the comfort level of the reg although is was a little big and sometimes got in the way of camera housings - but not too bad.
Parts - may be expensive - don't know - but worst thing is the LP hose is a unique poseidon part and incorporates the OP valve. If you travel it would be good to carry a spare as in many places it would be impossible to find a replacement quickly.
I don't have personal experience with serviceing, but have heard that this reg is quite challenging - didn't own mine long enough to find out. Although I have been servicing all my own regs for 25 + years, I would be a little cautious about servicenig a jetstream as I think it needs a very specialised set of tools - particularly an alignment tool. In my opinion it is hard enough to find a shop that can actually service ordinary regulators properly, and it would probably be harder to find one tha can service a jetstream or do it yourself.
Very nice reg in deep water though. The new Poseidon regs may be a better choice.

I tried my Jetstream this weekend. Great regulator. It is true that it performs better below 60 ft but it works just great above that as well. Bubble interference is not a problem, it's less that with "normal" regulators, but you still have them around.
It delivers huge amounts of air, but this doesn't affect (negatively) your air consumption rate; I agree this may even reduce that rate due to the extraordinary confort in breathing. One has to be careful with the purge valve though... it may blow your head off... I still don't know what is the OP valve (hose) for.
Ports put hoses so close together that make it impossible to have all of them with protectors.
Overall: great piece of equipment, with some unique characteristics...

Lucca:
First things first - the Poseidon regs are almost unique in maintaining an 'upstream' configuration on their second stages. This necessitates the provision of a relief valve - your OP valve - in the hose. Should there be a failure, the OP valve will dump excess pressure but still allow you to breathe safely.
The lack of protectors is not an accident. If you look at your hoses near the entry point, you will see a small hole in the collar by the screw thread. This allows you to visually check for hose slippage or wear. It is a deliberate safety feature and should not be covered with a protector.
Hope that helps. Poseidons rock - I wouldn't change my XStream setup for anything.
