Rebreathers Compared

KISS vs Poseidon vs ...

Product Review


"A friend who dives the KISS Sport suggested I look at a KISS Classic and my research showed it had what I was looking, for so I bought one. The purists warned me that that it was a bad step backwards. Diving with the Classic has proven to be fun, stress free and a lot easier than an eCCR. The Classic mCCR is just so safe and simple to learn, setup , use and maintain compared to an eCCR."
"With the Prism2 finally released, I was able to arrange a “Try Dive” in our pool. I definitely looked at the Prism2 with a lot of skepticism, trying to pick it apart, trying to find flaws or something that I just couldn’t deal with. Before the pool dive, I took the unit apart and found it to be really thought out and quality/finish of the materials to be great."
"After two days of diving with Posiedon rebreather I certainly didn't hate it as I expected. I wouldn't say I loved it, but I certainly respect the thought and attention to detail that has gone into the design. I’m not sure how big the recreational rebreather market is going to be, but whatever the size, the Discovery is well placed to satisfy that market."
