not to split hairs or start a pissing match, BUT your electronics could fail and leave you not noticing until its too late as well. I'm not convinced that there is enough hard evidence on failure mode analysis to say one method is better than another. Yes, doing a dil check every few minutes may be distracting during a dive, but practically speaking it will work, which is my point. mCCR is constantly trickling O2 at or close to your metablic rate anyway, so it'd be next to impossible to go so long as to not notice the PO2 drop on a dead sensor...you'd notice right away. You should be looking at your display more often that that if you are manually adding O2 now and then. |
