Your buoyancy is beautiful, your kit is streamline, your finning is methodical and grace is evident. You are the tech diver hovering in deco or the recreational diver creeping up to the reef for the perfect shot. Either way, you look like you belong underwater and you need a regulator that looks like it belongs there too.

The Poseidon Xstream Black has turned the best functioning regulator on the market into the best looking one as well. This self-balancing and utterly dependable regulator will have you respiring restfully and appearing downright awesome.

Xstream Black 1^st Stage:

In extreme (pun intended) environments, you would be hard pressed to find a better regulator to trust your life with. Just ask the US Navy; in their Antarctic testing this is the ONLY regulator that suffered absolutely no failures. With reliability checked off, what comes next? How about performance? The Xstream Black 1^st stage is self-balancing due to its ruby ball technology, which makes it a dream to breathe from. How about versatility? You can pair this 1^st stage with an Xstream, Jetstream or Cyklon 2^nd stage as well as with the Posiedon Atmosphere full-face mask. Thanks to it's all black finish you are getting a regulator that not only performs eloquently, but also looks uniquely eloquent.

Xstream Black Upstream 2^nd Stage:

You were most likely taught in your open water class that a downstream 2^nd stage regulator is preferable. The reason being is that (in theory) if your regulator suffered a failure in the 1^st stage it would stick open, resulting in a free flow. You would then be able to get to the surface while, sipping‚ on your free flowing regulator. That is all good and well but when you are breathing your precious deco gas at the most critical moments of your decompression, surfacing is not an option (or at least not one that bodes well for you.) You can also hardly afford to let a free flow drain your cylinder.

The Xstream 2^nd stage is an upstream regulator. You may have learned that if upstream regulators fail, they will fail, close, and cut you off from your air. In theory this is true, but Poseidon has added a safety valve (OPV) onto their first stage. This valve ensures that pressure inside the regulator will stay at a point in which you can breath normally in the event of a failure. To sum it all up, in the unlikely event that your regulator fails, it will not free flow; it will continue to breathe normally while you slowly make your way to the surface without suffering massive gas loss.

Xstream Black Octo:

In an out of air situation, would you rather your buddy pass you some cheap, barely functional alternate air source, or the world's most reliable regulator? Gone are the days of using some hardly adequate Octopus as your last chance lifeline to the surface. Poseidon believes that your Octopus should be as powerful and reliable as your primary. For that reason, the second stage Poseidon calls their Octopus is the exact same second stage that is used as the Xstream Black primary regulator. The only difference is the color of the exhaust cover.

Pressure Gauge Cirrus:

You want your pressure gauge to do a few things. You want it to be reliable, you want it to be easy to read, and you do not want it getting in the way. The Poseidon Cirrus Black Pressure Gauge is robust and compact and its fluorescent numbering on its black face make it easy to read. It is perfect for the diver who would rather dive analog over a transmitter, and for the diver who needs a reliable back up for their transmitter. You can trust that you will accurately know your air pressure in both BAR and PSI.
