Hi, just a quick intro.
I'm denzel, oc-ing for a long long time, but pretty fresh at Rebreather's.
I started in playing with an rgu/fm in holland and got the Rebreather-bug. Got a mate to explain a dolphin and lend it to me, a (long)while later got certified, got an atlantis, did some diving, playing and now finally ordered a kiss valve. Haven't decided on ppo2 monitoring tho. Mark Munro's 3 sensor/ display looked great, but here I read about a fair few of them flooding. Was this user error, or are the not too robust?
And any other options, specially in that price range?
I'm (we're) in australia at the moment, but in 3 weeks we're flying to holland to live there for a while, due to GF (australian) wanting to live there for a while, meet my family etc.. I'm already looking forward to running back to oz after that adventure.
Good to see a lot of familiar names here...

We have a fair share of ccr Dolphins here. I think mine is the most recent.
Some are very sophisticated conversions, others more simple .... at least so far.
I too considered the mark monroe PO2 monitors, I really like the DIY stuff. In the end, I went with the HSE PO2 monitor. I use an HSE computer and I'm used to the button interface, and I like the support that Gene gives his customers. Given the leak issues others have described, I'm very glad I went with the HSE.
It has occured to me, however, that leaks on the monroe monitors may be a result of dimensional tolerances between lots of the lexan tubing used for the housings. Out of roundness, or inside diameter surface irregularities would be hard for the O rings to seal reliably at depth. Might explain why some are constant problems and others never leak a drop. Perhaps chucking the tube in a lathe and making a minimal cleanup cut where the Orings seal would help the leaky ones.
As an alternative to the monroes, take a look at this one:

I think this is the box that JDZ uses for his monitors and has had it to great depths without problem.
Good luck with your conversion,
