Hi Pete,
When you say you're diving under FRC with little breathing reflex, when did you get contractions on inhale before starting FRC, and when do you get them now on inhale? Likewise, when do you get contractions on FRC?
How full are your lungs when you dive? I guess when I was trialling it we would take a big inhale then let roughly half out, perhaps a little less. It was comfortable up to a point, then when the contractions started they were quite vicious.
Also, is it wise to be doing safety diving on FRC? I recall Seb saying on our course last year that if you were under a situation where you had to perform a rescue dive you would need to do it under an inhale for a variety of reasons - you are lifting a dead weight and putting yourself under an enormous strain over a short period of time and for that type of effort inhale is much more appropriate.
I love the concept of FRC diving but it is very hard to adapt to (though i've seen some people take to it amazingly well). Now that I live in London my dive time is quite limited so FRC isn't too much of an option. I'll give it a nudge again when back in Australia eventually though.
Cheers,
Ben
