DIR- GUE Tec1 with CCR in the making?

If you can’t get a nitrox fill I think you’re going to have a tough time getting RB support

sofnolime and O2 for 8 dives is a lot easier to bring along than tanks.

Bailout.

But also can’t fill the bailout? Or the o2?

Okay.

Okay.

Using air as dil-out, which is fillable in a lot of places. O2 tanks don't take up near the space of +8 tanks for 2 divers which would be needed for 4 days of diving. I've made these trips diving OC and tank logistics are a pain but workable diving air, you just get stuck with pretty miserable bottom times.
These are just nitrox dives on CCR not Trimix I'm talking about.

Again, the risk/reward ratio of “I don’t have to carry a few tanks” vs “this machine might contribute to me blacking out and drowning” doesn’t line up.

8 tanks is not a lot of tanks.

The goal of diving a piece of equipment is backwards.

The goal should be to go see stuff. If you require a rebreather to do it then ok. But gear for the sake of gear ain’t it.

I actually never had an interest in ccr but my wife ended up needing a ccr for her master's thesis/work. So I jumped in with her. I definitely subscribed to only dive a ccr if necessary for the task at hand. Now I'm a little more lenient with it. One I want to dive the ccr regularly to stay proficient. And two, sometimes I don't "need" the ccr for the dive at hand, but it adds value such as extra time for enjoyment.
I can see both sides of the coin. I do think the masses jumping to ccr too quickly is going to catch up to us. The number of cave deaths I believe will increase as more ccr's are adopted. Not due to the inherent risks of the ccr, but from mediocre instruction. I listen in when I see classes going on and sometimes cave ccr classes are just about "hey lets go do a long ass dive." Very similar to what you see with some local instructors' dpv classes. I have literally overheard conversations where an instructor insinuates you can carry alot less bottles on ccr. It seems the idea that a broken ccr becomes oc doesn't stick in some peoples' heads.

How many ccr deaths have there been from not carrying enough gas?
All the ones I know of they died on the RB or before bailing out.

I agree that all of the deaths on ccr in a cave I can think of weren't from not carrying enough gas. Usually something else.
I reread what I wrote and I didn't express what I was trying to say well. I didn't mean specifically there's going to be more deaths due to not enough gas. I was more eluding to the lunacy I hear from instructors from time to time at dive sites that scares me because it goes against basic ccr principles. I believe more people getting into ccr will lead to more deaths due to bad ccr instruction, whether that be poor gas management, risk management, or failure management training.

 

[happy-diver]

Yeah I agree, if you are not going to build a theoretical knowledge base beyond what some instructor dude says

You should not be diving anything

 

[mattvish]

I can see where CCR would be a very useful tool for these trips even though the depth doesn't really require Trimix.

but it helps with deco... a lot

sure not as easy as air but shipping sorb is doable. O2 you get almost (to) everywhere, might be <150 bars but still enough
