Hi all
I'm doing the Rebreather research thing before I buy and am oscillating between the KC and a few others. At the moment I may possibly have the chance of buying an almost new Topaz..not sure yet...
This puts the Prism unit back in contention, I previously ruled it out because 9+ months of waiting for delivery is just too long for me!
Anyway, the scrubber. What's with the locking mechanism where it attaches to the head (the whole thing looks like deluxe tupperware), is it REALLY secure and tough?
It works pretty well, I had one leak but thats cause I let the Orings Dryout, you got to keep the lube up on them or they shrink, well thats what happend to mine anyway. Eventually the pins that hold the bucket break but you just drill em out and replace them with Stainless Steel Screws, these work much better.

And the secondary analogue handset, when your checking that is it a PITA to select all the sensors separately?
Yea look at replacing it with one from SubSea as soon as you can, digital readout all three cells in front of you.. When Jason finally gets stock of the PRISM ones.

Lastly, the proprietary sensors- is this an issue as opposed to most other units on the the market that use the more commonly available Teledyne units and can others be used in the unlikely event that something ever happens to SMI?
The SMS202 Sensors are IMNSHO the best part of the PRISM, the things are huge and if you get good ones will last for years, unlike R22D's that shit themselves whenever they feel like it.

Don't get me wrong, I've read a lot about the Prism- seen it dived once and so far it's a very attractive option, these are the only (maybe) potential issues with it that I can see!
I sold mine after 18 months and went to the Meg. The PRISM underwater is a great unit but the thing is just so fragile in its construction compared to other units out there. If you end up buying the PRISM make sure you get the cowling and NEVER dive without it, also carry a tube of DP190 and a spare secondary.
