Does anyone do deep enough/long enough OC trimix dives to justify air breaks? I doubt it. I do not do "air breaks" on my CCR. 1.3 setpoint. I might spike it to 1.6 at 70' for a bit. Old habits die hard.

Oxygen window is no longer a thing.

So that's the second time you said you are done with this thread. History says that typically people stick around for at least three "I'm done. I'm out". You got one more.

You don't define what your goals are (deep wrecks, mexican caves, shallow reefs, getting an RB to impress my clientele. etc.) That will make a difference in recommendations. However If the choice is between a Chop or a JJ (or a Meg) I would go with the JJ/Meg 100% of the time

You expected different in this thread?? You must be new here.

Worrying about CNS clock is a total waste of time. People tox at 75%. People tox at 100% and a lot don't at 110%+. It's never been proven to have any scientific validity.

18. You need length not strength.

That is so out there hypothetical that it doesn't border on fantasy vs reality it is miles into the fantasy realm.

The owner of the shop I worked with at the time was the one who examined the gear for the inquest. So I heard about what was up directly from the guy who checked the tanks and compressor for the RCMP. Compressor also had no OPV. Because it happened in 1994 links are very few. I could only find...

August 1994. Waterton National Park in southern Alberta. Shop owner from Calgary died from plugged steels that were hooked up to a compressor, got over filled, and exploded. There are a few more here on SB.

Where are you getting "My understanding" from? If it's from a dive shop then it's wrong. I'm just telling you what actual analysis shows. Sorry if it doesn't align with what you think it should be.

I can't say for the argon because it's not needed to be tested as per the standards for Medical O2 up here. CO and CO2 are negligible.

Possible vs reality. I've done analysis on membrane generated O2. None those values have ever broken standards for Medical O2 here in Canada. I don't even remember them showing up in any appreciable numbers in the samples I've done.

I've been to the arse end of the universe. Membrane compressors were putting out ~90% give or take a percent depending on the day.

I took a keg to Bikini in July in its' own bag. It wasn't a huge PITA as long as I had a cart. Once I got to Kwaj and had no cart, it definitely became huge hauling it around Ebeye. I paid $200CDN for the extra bag. Sorb cost me $160CDN. So $360CDN. The boat was charging $500US. So it was worth...

I got mine from Kent Tooling in the UK.

Those things are huge. I suppose if you need to jump start the dead battery on your Uboat they would be what you want. I prefer Teledyne Impulse connectors. Same benefits as claimed by the above mentioned connectors in the ad but much smaller.

I wish I knew about the bar stocked with Bud and Bud Light when I spent a couple of nights there in June. The bar at the hotel never seemed to be open.

Those are two totally different beasts. If the number of dives in your avatar is correct I would suggest neither right now. Single tank open circuit for a couple more years. You aren't ready for this.

That's what happens when they let the wife of the owner edit the manuals. They were terrible back in 1996 when I did my first course with IANTD and they were terrible in 2021 when I did my last one.
