If I suddently feel that something is wrong, my thoughts on OC bailout are:
- There is NO WAY I have time to reach down for my OC bailout second stage and switch
- There is little chance I have time to reach up for a BOW and turn a handle
Are these assumptions wrong?
..
yes and no
it depends
not all hits/reason to bail, are the same not all come on fast or are undetectable before its too late.
Personally my first reaction/habit to any feeling of weirdness or inappropriate increased breathing rate is to exhale through my nose a few times and fire the adv. Aware now and sensitive of a possible issue I am ready to turn the bov (if im using one) or go to OC if the fresh gas doesnt show signs of illeviating the problem to a manageable level
the main benefit to me in using a bov is the fact that with the increase breathing rate associated with a co2 hit divers are sometimes known (and i have personally experineced this) to be unable to force themselves to remove the dsv their panting from and switch to oc.
As an aside with the Panorma ffm its even easier. I just breath through my nose for instant blast of OC gas without changing anything whenever i feel weird.
Panorma FFM with side OC reg - good combo imho. I dont even use a bov with this mask for this reason as it gives me something to breathe OC whilst fumbling for my OC 2nd stages. The ability to keep breathing (through the nose) is a large stress reducer I find during times of stress/gas switching etc
