I'm sure I've seen a thread along the same lines previously. Anyone been using their wing as a BOB?
With a few hours to spare, an ABLJ that I got for a tenner off ebay, what's left of my old Ray and my spare DSV (from a Draeger FGT):
My new bailout rebreather!
The idea is:
- no electronics, it's purely a manual SCR. Breathe in, out, in, out, in, out, dump, add new gas, go back to start or pure O2 CCR mode at 6m
- no ADV, because it's running as my BCD there will always be a bit of gas in it
- no real change in kit loading, it's the BCD, it's running off gas I'm carrying anyway so no extra bottles, the only extra item is the scrubber which is small
I had a go on it the other day and I have to say I was impressed at how compact it felt (other than ABLJ's being shite for diving with in general). It worked as a manual SCR (I did a bit on pure O2 mode just to check it all worked), it wasn't a super-performer but it did work.
The next step if it proves viable is to move on to a wing so that I'm diving on exactly the same kit as I was before except for a small scrubber plugged in the bottom of the wing. I'm also considering the addition of a single cell but on the other hand, I know my manual SCR rates.
Before I waste any more money, has anyone else done it? The WOB with the chest mount was OK, I'm curious as to what it will be like with a wing. I'm curious too if I'm
I'd also like to know what the max depth for a Ray scrubber would be in SCR mode. At the moment it's split as to whether I'm considering deep bailout or a way of making deco gas go further on cave dives if I needed to go OC (or where the 6m stop is pushing the KISS over its 3hrs).
Cheers,
Stuart
