@Feather111 My sincerest condolensces.

@Bob DBF what was that quote you shared about narcosis? Along the lines of you don't realize you are narked often until it is too late or you are not able to handle an emergency. I think I should put that in my signature so I never forget the exact wording.

My only gripe with the metric system is that it is not based on the nautical mile. But that's because I'm in the maritime business.

One of my motivations for CCR is the lack of availability of helium in Greece. To support deep archaeological expeditions is a logistics nightmare. Sure you can find a few dive centers that carry helium. One in the Ionian Islands. One on Crete. One in the Dodanese. Not great coverage for 2000...

And if that policy gets used up by an incident with another instructor at the same shop, you are no longer covered.

Please explain the workload reduction procedures for dealing with emergencies: burst disk failure, hose ruptures, and other equipment failures. Dive buddy emergency like loss of consciousness or oxto convulsions. While I used to ridicule GUE (before the science caught up with them) for...

You completely misunderstood my post. Thank you for posting the direct links. You would think that these studies after peer review would end arguments. But then some people think the earth is flat even though the ancient Greeks figured out the circumference of the earth thousands of years ago...

One of my underwater archaeologist friends uses your fins. I would suspect that finning precision required for underwater archaeology exceeds that of underwater photography.

Your empirical observations (and mine) are statistically insignificant to the volume of data that goes into a scientific study. Nope. Doesn't affect my sensibility whatsoever. There is no scuba police and people are free to do whatever they wish. I won't deny I have not had a number of hold...

There's been a surprising shift from PADI to SSI in some places, like Greece. According to one dive center owner that is a friend of mine, it was based on cost, not the flexibility of training. That is something I have personally experienced shortly after crossing over as I was teaching for a...

I was being facetitious. There is no way Dr. Mitchell would get involved with this trainwreck. While I do not speak for him obviously, I believe his focus is providing results of scientific research in ways that people can understand and apply to their own diving. For those who ignore peer...

So I'm genuinely curious, what training does FFESM/CMAS provide that overcomes physiology? (and I wonder if Dr. Simon Mitchell has seen this thread and thought "Oh God, I'm staying away from this goat rodeo)

I only did one deep dive on air to 55 meters/180 feet on the Warren wreck (overshot it). I was diving with two other guys. One guy was so narced (and denied it afterwards) that he couldn't signal back "okay". His head followed my light on the bottom like a cat following a laser pointer...

There is a risk to rescuers and public safety divers. There was a car that went off the road into a river in King County. It was so sketchy one of the members of the King County sheriff's department quit after one look (source: king county deputy that's a friend of mine. He was also the first...

So this is where I take issue with all agencies' training materials. Nowhere do they discuss the value of a BFK in addressing disputes that occur underwater. Had you had the Rambo IV scuba edition survival knife strapped to your chest, that DMC would not have laid a finger on you. (People...

That's because they don't know that it is supposed to be a big deal. That's the beauty of students who have zero knowledge about diving. Whatever you do, they consider normal (example, the dive planning document I provided, one of my students showed it to his friends who thought it was great...

Let's discuss this offline and loop back when we converge. I don't want the exchanges to be viewed as bickering or detracting from the overall topic. But it is something important (to me at least) to discuss.

That's quite typical. When I last taught for a shop, that was how I taught. And it is absolutely doable as I needed LESS time with 8 students when teaching NB/T than I did than on the knees. In confined water, it is easy to do. As students do not finish the timed swim at the same time, an...

Scenario: diver is neutrally buoyant and foot heavy. So just breathing they are horizontal in the water column rising/falling slightly with their breath. They need to scull to get horizontal. I should have said sculling, not finning. I don't wish to be pedantic that he might be still be...

So your giving an example video of a platinum pro course director that in my opinion has no business teaching instructors, much less teach open water students. He has countless atrocious demonstration videos where he's neutrally buoyant but out of trim and finning constantly. If you don't...
