No breakthrough or channeling, was just a panic attack that caused my breathing to accelerate, which over came the scrubber. Like others, in my mind, there was no physical way I was able to remove the loop and replace it with a second stage even though it was right in front of my face. I thought I would drown. About approximately 2-3 minutes inot it, somehow I managed to get my breathing under control. The RMS actual;ly was a help as it was showing me that the scrubber was perfectly fine throughout this episode. Re: pitfalls and benifits of a BOV, someone online once said that "if I am wrong about BOV's I have wasted €1,000 of my money. If you are wrong it might just cost you your life". On that basis, why gamble, err on the side of caution.
Of course it is super easy to armchair quarterback other people's stories, and I wasn't there when you had your issue. The way you describe it sounds like a textbook case of hypercapnia. The part about not being able to remove the loop to switch to a BO reg, I mean.
With no breakthrough or channeling, I don't see how you would go from fine to hypercapnic in an instant.
Let me repeat myself. I wasn't there. So, please don't take this as some kind of accusation. I'm trying to share what I know and ask questions so that I can learn from what happened to you.
The way you describe it makes me have to wonder if you were actually hypercapnic, or if you were simply panicked and breathing really fast from that. Because, if you were not hypercapnic, then the next question is, did you even need to bail off the loop? Getting your breathing under control after 2 - 3 minutes also suggests that it was not a hypercapnic hit.
All of which circles back to, is the benefit of a BOV worth the downsides. You're giving this example to rationalize using a BOV - but in your example you describe having THE symptom that is a reason for a BOV (i.e. that you could not remove the DSV to insert a BO reg), and yet you survived just fine despite not having a BOV. So, would there have been an actual benefit to you in that situation if you had had a BOV?
Shouldn’t it be easy if you first put on the gag strap and then the necklace for the BO regulator? In case of BO, drop the BOV and get on the regulator that sits on top of it. I still need to try it out but this is how I would do it.
My training was bungee necklace BO first, then loop on top of that.
I don't think it would work so good to have the OC reg and hose on top of the loop.
But, if you try it, let us know how you feel like it works.
