AST sensors

[RainPilot]

Is anyone here running those in a Poseidon or other rebreather? Thoughts or experience on them?

I have been running a backup cell sensor on a Poseidon SSS cell for about a year now. Very sweet. Instantly on, no calibration, every time I check it against a known gas it is bang-on. The only reason I don't run my full units on them as primary, is that I have been waiting to send my heads in for the upgrade. I would not hesitate to dive the SSS in any situation.

I have my SSS cell as a primary, on my Se7en+. I haven't got a huge amount of dives on it, but so far it has worked flawlessly. I think it is a great improvement in technology. The cost over 10 years (the presumed lifespan of the SSS cell), is comparable to ten galvanic sensors. I wonder if it could also be worth replacing the secondary with another SSS cell, but I am probably going too far, at least till prices go down more.
