PADI standards require that divers wait 6 hrs after arrival at altitude before diving as well. Interesting you "forgot" to mention that.The two decent sites for diving to Colorado are at about 4,600 feet in New Mexico and at about 6,000 feet in Utah. I cannot even remotely estimate how many thousands and thousands and thousands of people have done their certification dives from all major agencies at those two sites without taking altitude into consideration.
Yes, PADI does say anything above 1,000 feet requires special considerations. What are those special considerations?
I had an interesting conversation with an SSI instructor from Colorado Springs when I met him last year. He said they teach a lot of altitude classes, but they don't use the SSI material for the academic content of the class. They use the articles I wrote on altitude diving for the class instead. Here is one of them if you want to learn something about diving at altitude.
- You have to treat every 1,000 feet elevation gain as two pressure groups if you are using tables to compute your dives. Most people go to the site from nearly the same elevation, so there is little to no elevation gain. When we take students to New Mexico, there is actually an elevation loss. If the group in this case had driven as fast as a car could go from sea level to the dive site, they would have had enough of a surface interval during the trip to be starting from scratch. Starting from where they were to get to the dive site, there was no real elevation gain.
- If you are using tables, you have to plan your depths differently. If you are using computers that correct for altitude, as they were in this case, you don't have to do anything different.
As far as not taking altitude into consideration, sounds like normalization of deviance, which is IMHO all too common in this industry.
I could list them for hours and all have pretty good "success" rates, they all have killed a person or few that otherwise would have lived. But statistically in the grand scheme of things compared to other activities that can be explained away, and who wants to do the best they can for their freaking students anyhow? That's old school. Let's just get their money, issue the card and that is one more towards getting a nice certificate to frame for the wall in appreciation from the agency and gets the instructor closer to getting their next highest instructor/CD/IT whatever done.
For a guy that is so determined to always frame every accident in "the instructor violated standards, the standards are perfect", you sure are celebrating a SSI instr violating the SSI standards. I guess when it is using what is IMHO an over simplified and in some areas seriously flawed misunderstanding of the principles and variables involved guide that YOU wrote.. you get the ego rush.
Just like you do when you are always going on about having been the guy that invented teaching diving neutral and in trim... when in fact you took what some others here were doing with other agencies and wrote it up nicely and took to PADI.
You are so predicable it's sad.
