Kensuf, where/who is making that Fathom stand?

Depending on the wrecks you're going to do, it would probably be worth having the extra gas, no? I do a lot of shore diving with 5-10 minute walks from my vehicle to the water, so having the extra weight of 133s is pretty noticeable. If you're just going 50ft from your vehicle to the water, or...

This happened at 10 Mile Point I'm assuming.....

OP, are you already qualified to dive O2 rebreathers within the military? Or you just Want to do it because it looks cool out? You said you're a Marine so I think they use LAR V? The units all function the same. Some have a T valve for automatic injection, some have a manual addition valve...

Can you explain what OP was even asking to a non CCR diver? I'm assuming IBCD is isobaric counter diffusion. I haven't gone CCR yet (doing training in a few months) but on my GUE T2 class I never learned about planning your deep/intermediate deco gases to avoid IBCD or what it really was.

OP, I don't think you're going to find too much validation for your idea on Scubaboard. That being said, you have made up your mind about diving FFM, so I'll just give an opinion on the original question: don't add a quick connect to your 1.5m secondary reg hose. It's totally unnecessary. I can...

Yeah.... I got that. Assembling the cylinders wasn't the problem. Diverite actually just got back to me and measured their bands and said they aren't actually good for 8.5" CtoC. Guess I'm not crazy.

Ok, I need some input to see if I'm totally crazy or really having an issue. I have a set of Faber LP50s I am trying to twin up with Diverite 5.5in bands. I'm am installing them the way I have been showed which is to slowly thread the cross bar into the valves to the right distance 8.5" and...

You know what I made a mistake on my calculation on my last post. Breathing EAN32 at the surface gives an EAD being at 0.86 ATA, but that is not 1.4m above sea level. I don't know what altitude that would be, any ways, the point remains, the difference in off gassing would be negligible.

Probably best to look at the potential benefits of breathing nitrox on the surface in terms of EAD (equivalent air depth). Using EAN32 as an example : ((0.68 x 1ATA / 0.79) - 1 ATA) x 10 = 1.4 metres ABOVE surface. So would it have an effect? Sure, but how much? I don't think it would be enough...

I see guys say that a lot but isn't that mentality a little bit of a hold over from the days where CCRs were a lot less reliable, a lot higher risk, and the only people using them were doing exploration dives? In my neck of the woods, I see CCR guys doing rec profiles and basic tec profiles...

This thread is getting hilarious to read. Also how many more variations of Hartattack's username can @boat sju come up with?

I have one of the 30lb DGX wings. I really like it actually. The outer Cordura shell is stitched together really well. It feels like my Halcyon wings. OP I dove with my 40lb Evolve wing on singles and it was super annoying, but manageable.

I was just talking to an instructor about what courses give you what certs, specifically for IANTD because it is not clear. Apparently CCR Mod 1 is now deco "as required".

Yeah I saw on the Fathom price list he sells a "Tech Pack" that comes with LP50s + LOLA and a couple other things for a decent price, but I don't think it will actually save me any money from buying the package once I ship it to Canada and pay duties/ taxes, plus I already have LP50s. Easier to...

What length of cross connect whip are people here using to connect their LOLA valves when diving a Fathom in the boat rig?

If you look at GUE Fundamentals materials from 5+ years ago it actually includes the 30m/:20min set point for air diving with average depth/ on the fly planning for when 32% is not an available gas. Pretty sure it uses 40min at 18m though instead of 50, just because it's easier to work with...

Right but did I not just do damage to the cross bar?

I just put a twinset together with diverite bands and an manifold of an unknown brand although I believe it is the same as the Halcyon manifolds. I lined everything up and tightened the bands, but then noticed that the connection on the cross bar to the right valve is just slight crooked. After...
