| Conclusion?
It seems;
A BOB is the more practical style
It needs to be streamlined and no larger than a stage
It needs to be full CCR
It needs an ADV
It needs an autodump or some method of making the ascent "hands-off"
It needs to allow instant OC bailout (via the ADV) until the diver is ready to fly it CCR
It needs to be "sealed" - in other words it needs to remain clean, sterile and dry long term until/if it is needed
It needs minimal/no setting up pre- and post-dive
It needs to cope at least with prolonged deco (up to 2 hrs?)
It needs PO2 monitoring
It should be at the correct mix always, for instant use
It should be robust enough to treat like a stage
It should be cheap
Have I missed anything?
Having acquired a YBOD so I will always have enough gas, it seems daft for me not to think the same way about bailout. And as far as extra hassle is concerned, I don't find the YBOD is that complicated, so why should a BOB be overwhelming? Filling a stage with the correct mix would take as much time. |
