The second stage has lovers and haters, but as a side exhaust, it just shouldn't put bubbles in your face. I don't get that complaint, Tim.
What can I say. I’ve used XStream seconds and Jetstream seconds. Multiple dives each time I’ve tried, and I’ve tried multiple times with each design. I dive them with a long hose, without a 90* elbow. When I do so in horizontal trim, I get bubbles across my line of sight and they get caught in my hood. Even 20* head-up trim tends to lessen or eliminate that. But in solid horizontal trim i get bubbles and a cold head.
I’ve been told this is less of a problem when the hose isn’t “hog tied” around your neck, or by putting a 90* elbow (or swivel?) on it. I’m really not interested in either of those work-arounds, so I just keep diving my Apeks clones.
And maybe the fault is my big, bulbous head. While you may not “get” my complaint, I certainly do. But it’s just an anecdote, and my N only equals 1…
I mentioned the “throwing air” issue but I’ve never really considered it that much of an issue for me. I just know others do. I will say: be careful hitting that purge button! I’ve frozen a second stage on a cold (but not ice) dive, and I’ve caused myself to choke from high-speed droplets hitting the back of my throat: put your tongue in the mouthpiece first!

Like I said, I really want to like them. They are the coolest piece of regulator engineering I’ve ever seen. But even if your IP settings make them breathe exactly like any other reg, I don’t think it’ll solve my exhaust issue…
But heck: I still have a set of XStream firsts with Jetstream seconds (plus some Odin firsts with OPV’s)…. What’s another try gonna cost me?
