Over the past year, increased regulatory pressure in multiple regions like UK OFCOM and Australia's eSafety has led to higher operational costs, including infrastructure, security, and the need to work with more specialized service providers to keep the site online and stable.

There appears to be a few different variations and models of 3M Scott SCBD. There is the Vision 3 and ProMask model each with different variations. Is there any recommend model and variation?
Most of the SCBD masks don't come with the air supply valve so you either need to buy this separately or buy the 3M Scott RAS Positive Pressure Respiratory Airline Apparatus. Is this correct?With the RAS, it seems to have enough length to not require an extension hose. For connecting the RAS to the regulator, the RAS uses a male CEN type connector, would this still work with the 3/8 BSP Female to Rectus 95KS Female or would I need a 3/8 BSP Female to a quick release coupling?
Is it quite rough to lose consciousness or is it more smooth, gentle and painless? I will CTB tomorrow if everything works out. Thank you for everyone helping me here on this forum.

Not sure, I haven't seen anyone say for certain. Several people have presumed that @GasMonkey has ctb as it's unlikely he'd be off the site for this long.
I'm not sure about @Das Nichts, I haven't heard anything about him.

Hello, in a few months I will probably do it with the SCUBA method (rubber scuba diving mask). Do you have any advice to give me ?
I would like to do it in a hotel room, I think I need to bring a large suitcase to put the gas bottle surrounded by some clothes so it doesn't look suspicious.

I'm trying to determine the exact type of male connector that was used for my EEBD hose.
I think I may have found the thread size, but I will need to wait for the adapters to arrive to confirm it.
The only problem: The hole in the male connector is really small as seen here.
On that photo it's not visible because of the lighting, but the actual hole through which the breathing air passes, is not even a millimeter wide.
I'm wondering whether that will cause issues.
And I wish I knew the correct technical term for it already.
I skimmed countless of websites and articles online for hours but was still not able to find anything.
Why are you leaving that connector on the hose? Does it fit onto a coupling/coupler?
Why not just cut the connector off and attach the hose directly to the regulator hose barb, like k1w1 and others did?
Did your regulator come with a hose barb like this? :
I managed to remove the hose from the regulator, something which apparently isn't possible on all EEBD sets.
I was really happy when I did, so I want to try to connect it using an adapter first.

I did a blackout test with my SCUBA setup and it wasn't rough at all. It felt more like falling asleep, maybe a little bit more strange. It also goes really fast and no suffocating feeling. I also guess SI isn't a big issue here, because you don't have the feeling that you're dying.

Sounds good. Out of curiosity: Did you notice any smell? Did the gas feel cold? Basically, was there any difference between breathing air and pure nitrogen?

I was, as you can read in my previous post in this thread, nervous. I was really focused on blacking out. So my judgement might be a little bit clouded on this aspect, but I didn't smell anything and it also didn't feel cold. I stored my cylinder at normal room temperature so that might have helped. If you look from a theoretical perspective it also makes sense. Normal air contains 80% nitrogen and doesn't smell neither. Divers basically have the same setup only without O2 and CO2 and their air is also not cold I guess.

Thank you. I know the theoretical details - inert gas: colorless, odorless, and tasteless, non-flammable and so on. I've also seen videos of people passing out on inert gas more or less instantly and without knowing what's going on. But, well, better be sure about it. I guess if there were a smell the cylinder might be compromised.
Keeping the gas at room temperature is a good idea. Remove anything that could trigger SI.

Have you done your test with the full face rubber diving mask (sold with the brand names Poseidon and Pegasus) please? Because I plan to go with this mask, but I haven't ordered them yet

No I have the Ocean Reef neptune III. I pressed the mask against my face during the test without the straps tightened, so it could fall off when I lost consciousness.
You can store it for a while, but I remember someone on the forum mentioned their cylinder's pressure dropped after a long time.
I can't seem to find the post/thread.
It doesn't expire, but the PSI slowly drops, I've had mine 17 months now, the PSI has dropped from 2200 to 1650(but no drop in the last 4 months), but since its 3500 liters, there's still enough Nitrogen in there to kill me 12 times

Many years--When you turn the valve on, it will jump to the PSI number--MY PSI was originally 2200 back in April 2022, now its down to 1600(huge 3500 liter tank so there's still enough to kill me more than ten times), so very slow leakage
I just tried to CTB and failed I didn't even black out. Which means there is still too much oxygen. I had bought a oxygen meter and placed it in the eebd hood and It dropped to 1% and stayed steady there, is that not enough to at least cause blackout? It seemed that it was at least low enough to give a killer headache but my vision and hearing remained about the same I had it on I think about a minute or two before I panicked and pulled off the hood. I checked the hose connections with soapy water and didn't notice any leaks. I think it might be the hood and my breathing sucking in air from outside where the face mask interface is.

I also had prepared the things for this method with eebd, but I have seen too many comments where they try it for minutes, and not "A couple of breaths" For a while I felt like this would be a peaceful and reliable way out, but I'm to scared about this method now, and ask myself. Will I pass out? If I pass out will I wake up again? Will I end up with serious brain damage?
Of course I want to leave this world physically peaceful, but not at the expense of reliability. I feel so stuck.

I think the problem is none of this is standard and item being used not for their intended purpose and as such it could be a your mileage may vary situation based on where you source your parts and what kind and purity of gas because the principal behind it is sound. I think the take way is test your setup not that this doesn't work reliably. I am definitely still keep going with inert gas but I am definitely gonna try a blackout test first before the actual CTB moment.
