Hello everyone.. Thanks in advance..
If you do, how do you switch gases?
A gas switching block like here http://oxycheq.com/OmniSwivel_Applications.html on the bottom right?
Possibly some sort of manifold with quick disconnects?
If one were to use a manifold without a gas switching block, and were to leave the quick disconnects connected.. would the 1st stage regulator with the highest intermediate pressure deliver the contents of it's tank until the tank pressure fell below the intermediate pressure of the second tank?
And do you run both your bottom gas and your O2 Deco through your FFM's integrated regulator (such as AGA or Poseidon) (I have limited training on Deco, but I have read that once you run 'scuba grade' air through a reg it's supposidly not oxygen clean anymore.. i don't know if that applies to Nitrox as well, since it appears most regulators are only rated to 40% Oxygen..
My intentions at this point are to run the gas line from the second stage regulator to a small manifold having two additional ports which are quick disconnect. This way I could have _only_ the tank I am actively breathing from connected, and for gas switches never loose pressure to my second stage by _temporarily_ having the tank I am removing and the tank I am adding connected at the same time.
Thoughts?
My background:
I'm NSS-CDS Basic Cave certified, have been mentored by my instructor in both Sidemount and Decompression Proceedures, and have _not_ used a FFM yet.
I am interested in moving to a rebreather in the future, and would like to utilize an FFM for purposes of attempting to prevent drowning in the event of oxygen toxicity or hypercapnia. That said I would like to get experience on said FFM before obtaining a rebreather..
I am interested in the AGA and Poseidon FFM's mostly, I have looked at and read about the KM 48 but am not really considering it.
Thanks again,
Scott
