Rebreather "Round Up"

[ghosch]

I think CO2 monitors are a BAD IDEA! Most are incapable of determining the most critical problems (loose o-rings/poor packing/dead scrubber material/etc) instead they focus on temperature and time. I think that a CO2 monitor will give divers a false sense of security about scrubber life and the abuse of the "3 hour" limit will increase. >

The same could be said about OxyGauges on an SCR

What I don't understand is why it is so difficult to make a CO2 sensor. Portable CO2 detection systems are comercially available for confined space work. They have been available for years. They do require some calibration and maintenance.

Whether or not they should be on the unit is a different question.
