Bailout needs the OC diving skills, especially no-tox drills.

Going to a rebreather as a competent OC diver makes bailing out trivial and safe.

Again, there are multiple people besides me on this thread who get narced below 100ft. Doing AN/DP on air is dangerous for us. No helium or not enough helium for OC fills for Helitrox means AN/DP has to be done on CCR.

My instructor’s shop has stopped all OC trimix fills. CCR only.

Hoo boy, Dr. Neal Pollack on rebreathers?
 
Maybe someone is interested in it:


Within GUE, there are many more CCR1 enrollment than tech2 OC.

I would go for Tech2 :)

And if you can’t get any helium?

That is where things get backwards. In a small window, about 100-150', with zero Helium available I would take OC over CCR. Beyond that it goes into I'm not making the dive. I have a little more tolerance for air on OC than I do on CCR. Even then it would be a shorter dive than I would plan on CCR.

CCR every time even for a shallow dive. You might even be able to blag some helium as so little's required.

OK, maybe not so keen on a shore dive if sidemount's available :cool:

Actually, I was asking the poster 1-2 above you who said he’d choose Tech 2 over CCR 1.

Sorry, my answer was not complete... I will do tech2 before rebreather :)

{EDIT: I already consulted several cardiologists and I am clear to dive with no depths limit - see post #246 - for now at least - so when you will read that I have a heart condition, please don't get crazy :) }

My reasoning is the following:
- I believe the experience in OC is not necessary but very valuable.
- Before spending a massive amount of money on a rebreather, I want to ensure that I like deep stuff.
- I NEED to test if I can handle heavy equipment (I have a heart condition). Because one of my final aims is project diving with GUE, and the rebreather is heavy, I first want to test heavy OC equipment (buying a 10k rebreather to discover that I can't handle it does not look like a terrific idea).

Now, if I realize that I do not like deep diving (which may happen if I find long deco stops too dull), I will stick to normoxic OC dives. I already had some issues finding helium, but not enough to justify the purchase of a rebreather. If I have these troubles more often in the future, I will purchase a rebreather and get the training.

If I realize that handling heavy stuff is a problem, I may evaluate a small rebreather out of GUE. I am thinking of a triton or a sidewinder (but, to be honest, it's just a guess, I don't even know how much they do weight, and right now, it's too early to think about it).
