DIR- GUE GUE CCR Discussion (split from Tec Pass Thread)

[justinthedeeps]

CCR1 essentially is Fundies on CCR.

So duck dive kicking in formation for six hours at 3 metres then?

Aside from hating anything with a battery (his can light is actually hand cranked throughout the dive), the T1-CCR1-CCR2 progression bypassing T2 is what gets him worked up.

Affirmative
Only having T1 for an OC background is marginal at best

I think it can be fine. But it requires some honest self assessment. When I took CCR1, I had a few hundred OC cave/DPV/stage dives under my belt, 40 or so in the T1 range. CCR1 was a natural progression. Someone at 25 dives out of T1? No chance. Then again, you could get from tech pass to CCR in 50 dives before if you wanted to. I think as long as you aren't trying to go zero to hero, it offers a better process for learning to dive the unit in progressively more demanding environments. Especially if you look at cave CCR as a sort of primer for CCR2 and get a decent chunk of experience between classes.

So you have not taken a hypoxic or even a 2 deco bottle course at all?

The JJ with the backmounted 50s is pretty much the worst hobgoblin of a CCR for caves but that's another issue

Hypoxic, no. I've gotten experience with two deco gas diving through other routes.

Would you mind to elaborate on this? In a new thread if needed...

My T2 class was unfortunately cancelled and postponed to next year by Corona... but there seem to be plenty of CCR classes going around, and more cave divers that I know seem to be adopting the JJ. I’m not convinced yet, but as it gets harder and harder to take both the T2 class and do T2 dives .... I don’t refer to He but finding buddies.

anyways, what’s the issue with the JJ in caves?

Not to speak for rjack, but I'm pretty sure he's specifically talking about the JJ in GUE configuration with backmounted 50s. The JJ is just fine in caves, and even in the GUE configuration it's perfectly fine, but there are short comings to backmounting 50s. In my opinion the absolute biggest one is that it requires multiple stages for big dives. When I got my ccr I was very excited to only have to sidemount 50s. Unfortunately very quickly in class I learned that 50s don't give you alot of range in caves in the 80-100ft if you do proper gas planning. So you either need to carry 1 or more stages or go to bigger bailout or both. In the GUE configuration you can't go bigger than 50s (at least I've never seen it), so to get to the henkle in Ginnie you'd realistically need 2 stages (assuming proper gas planning with heavy conservancy). It could be done with 1 stage, but is dependent on your personal tolerances when calculating gas. Also the JJ with 50s is pretty big, and due to size isn't ideal for some caves. But I've dove my ccr with backmounted 50s and in appropriately sized cave it's nice to just strap it on and jump in the water. Personally though I do prefer sidemounted bailout in caves.

Plus the BOV is on the roll off post.

The oxygen tank sticks up behind you making the unit asymmetric at a weird angle. I’m almost certain that line would love to sneak back there and cause some fun.

There’s no way to add offboard gas.

No practical way to increase your onboard bailout supply as the unit is already very wide.

The absence of a backup reg is inconsistent with GUE open circuit configuration. The class is also taught optionally without a BOV which I think is absolutely insane.

Sorry, do you really mean they failed? Or do they just got a provisional?

Failed failed. One on day 1, another on day 3. I spoke to one of them about it and he said his instructor doesn't do provisionals... so bye bye course fee!

They were gutted of course but went on to work on their fundamentals and eventually got their T1 the second time.

I thought there was a mav that could be added to allow offboarding. Maybe I'm mistaken.

I assumed the class was taught with both a long hose and bungeed second. Sounds like no.
