I worked at a lab that used FTIR (Fourier-transform infrared spectroscopy - Wikipedia) analyzers for air samples so I understand the science. But for the rest of the group, the link you posted is a pretty good reference.

Way too many parameters for me to remember but here we go. Pistons. Sherwood blizzard (salt), S'pro mk20 ( few times in fresh). Freeflows because of 1st stage freezing Water temps were probably around 3C. Diaphragms- never seen it. Even that time I used a Poseidon 1st that was encased in 1/4"...

The Force of George Irvine is strong in this one Grasshopper. It's about time someone livened up this place.

I see a dog was helping as well.

It's been re-re-re hashed many times over many years why DIR does what it does. If you want to argue personal choice, you are in the wrong forum.

You must be be new here.

If you are GUE trained you can participate in GUE projects and also ones put on by non-GUE groups. If you train with TDI you most likely won't be able to dive on GUE projects. If I was just starting out I would go with the GUE training.

Why? Why do you have a burning desire to become an instructor? Why not just be a diver?

I know quite a few friends (mutual and otherwise) that quit teaching in the past year because it just wasn't worth it.

When I worked in an air testing lab (ok, full disclosure I owned the place) pretty much every compressor from every fire hall, scuba shop, or oil field SCBA fill station, met and exceeded OCA standards without anything other than the filtration that came with the unit. Of the thousands of tests...

That dope would have to come from inside Canada and/or be willing to travel to Winnipeg (said nobody ever) to file the lawsuit.

Or apparently to be a deep air advocate.

There are a few pictures around when it was operating. This is the wikipedia entry with a picture from 1894. Hog posts and hog chains were installed sometime after this and before the sinking to stabilise the hull. City of Ainsworth (paddle steamer) - Wikipedia Nothing is still standing...

Between August 28 and September 2, a team of experienced scuba divers re-located and dove on the remains of the 25m (84 ft) sternwheeler “City of Ainsworth” in Kootenay Lake, BC. The City of Ainsworth was lost during stormy conditions on November 29, 1898. Its’ whereabouts were unknown until...

The average diver doesn't do 60m dives nor should the average diver be diving CCR.

No

If that is what it takes to make sure I have access to helium I'm in. However I better run this one by the wife first. She was OK with me buying a compressor and booster years ago. This should be OK with her as well.

I only d'load from my Nerd2. I don't bother with the Petrel. I used to but didn't see the point

I absolutely value the skills learned in taking OC trimix first. It was always (still is) my thought that unless one is solid on OC then one has no business going to CC. If someone has to bail out on a rebreather they are an OC diver. When I switched from OC trimix to CCR the bailout part was...

Outside pockets of the US where Helium is available and relatively inexpensive, there is no future for OC mixed gas. So that element of the roundtable is moot.
