Cave CCR?

[tbone1004]

So how challenging is cave buoyancy with a CCR? As someone who has never used a CCR it seems that you would have to learn buoyancy all over again and the precision buoyancy that cave diving requires may take quite a long time to acquire.

@kensuf hit the nail on the head. It's like trying to run on ice. Once you figure out how to do it, it's really not that hard *grew up in the great white north, so have more than enough experience with ice...*, but learning to do it is going to be a bit ugly. The key to learning how to do it, is anticipating what you have to do long before you have to do it and being proactive vs. reactive like @Superlyte27 pointed out since Pete is being a proper font of wisdom this week

Today was day 1 of my Fathom CCR course (first rebreather) and this thread was in my head throughout and very helpful. I kept thinking that I read to "stay ahead of buoyancy" so I need to do it. I actually think day 1 went much better than expected. Buoyancy sucked at times (ADVs like to fire at the worst time apparently), but as a whole it was pretty good 90% of the time. Hovering perfectly still and feeling solid is not nearly as easy as OC.
Thanks for all of the helpful posts. They actually helped me know what to expect a little before starting class.

Like dancing and sex, it gets better with practice.

Thanks. The one dumb thing I keep doing is inhaling hard and holding it when I'm descending unexpectedly since that's what I do OC. Except in OC it's a little breath. In CC I find myself inhaling harder and harder since it's "not working" and then the ADV fires and it's back up we go, oops now I need to dump, oops too much. It's coming along though.

After diving sm for many years I was afraid I would potentially hate having a bm unit, but the Fathom is so light I don't notice it. It feels like diving sidemount (bailout) with a single al80 on your back. Much nicer than expected. Of course just like sm, it's a little fidgety getting bailout tanks setup perfect.
