CCR Bailout Planning

[twaldo]

What's with all the "?" in my post. It looks like I have some rare form of typed tourettes syndrome.

Guessing your first post was from a mobile platform and your 2nd was from a pc.... everywhere you wanted an apostrophe you got a question mark.

One problem planning bailout on CCR, is the fact that your SAC rate gets worse the longer you dive CCRs. You get used to breathing anytime you want, so your SAC rate gets worse. I plan this way. A normal OC diver uses 1/3 in, 1/3 out/ and 1/3 reserve. Therefore you can swim three times a far on bailout as you can on OC. Some would say that the current helps you out, so you could get by with less gas. The problem with that is, what happens if there is a silt out, etc? I dive sidemount steel tanks. I figure I need the weight to counteract the drysuit, and you can't breathe lead

It is the forum software. Most punctuation isn't recognized, so it uses a question mark instead.

Found that to be sufficient for any dives above 300'

So then why wouldn't you treat the rebreather has the first third, and the bailout as the other 2/3rds? That scheme seems more analogous - you're carrying twice the gas needed to exit from max penetration.

That seems a little agressive if I'm reading you correctly. So if I can easily swim 1500 feet in Ginnie OC on 1/3s, I should assume my bailout could get me to 4500 ft? I'd probably bring more than a set of 85s (if that's what I used for the 1500 feet).


I'm new and haven't stepped into a cave yet with my ccr, so I could be way off base here.

My SAC hasn't changed. Might be because I'm still teaching on OC occasionally.

I've seen some pretty bad CCR Bailout planning. I think it's pretty simple stuff. Just plan for worst case scenario.

Buddiies left you, ccr had total unrecoverable flood at max penetration, vis is zero, and you're stuck.
Pretty much how my dive with James and Michelle went one day. LOL

"You can't be too certain" said the nun and put a condom on a candle.


Sounds like a similar line of reasoning.
