This is more of a generic response rather than to this specific quote. The question is this--how do you really know what is right? I had my first knee surgery more than 40 years ago, and I can't estimate the number of orthopedists I have had in the intervening years leading up to my present two...

Why did the diver go to the surface? We don't know what happened, but it is perfectly possible for a highly skilled diver to have this happen under the right circumstances. It happened to a former instructor of mine, a TDI tech instructor; UTD tech instructor; and cave diver. He was at 100 feet...

The standards call for him to assess the student's overall ability to do a dive. The courts said he did not do that, so that means that the instructor did not meet PADI standards. As I read it, the student had the prerequisite requirements for the class, but that was not enough--the instructor...

The second sentence was not made by the court, as can be seen in the full translation. The statement that PADI's requirements are "so weak" was made by leadduck, not the court. The court did say that PADI's requirements call for an assessment of the student's ability before the dive, which was...

I thought I would provide a Google translation of the full article. .......................................................................................................................... A diving student dies during a course in Lake Thun. The Bern Higher Court finds the diving instructor...

To add to the puzzlement.... The victim was an instructor, so he must have finished AOW, which further means he had completed the deep dive requirement of the AOW certification. That dive is also the first dive of the deep diver specialty. Now, that dive is shallower than 100 feet, but we are...

It is hard to tell exactly what happened from the article, but there was more to the verdict than in the OP summary. The accused instructor was said to have not been responsive to signs of difficulty and conscious signals made by the victim indicating trouble. He looked away from the student and...

There are two distinct ways of doing a back kick. I use the sidewall as the propelling surface, and the Quattro sidewall is as big as the Jet's.

That's news to me. I don't have any trouble.

I don't know how recent this change can be, since I have been over 70 for 5 years and have had DAN insurance for all that time.

Dive agencies train and certify dive professionals (divemasters and instructors). They do not control the conditions of their employment, though. A local dive operation typically employs divemasters and instructors, and they tell them when to work, where to work, and how to work. Some employers...

By far the most common reason for a scuba fatality is a medical issue, like a heart attack. Heart attacks are also the most common cause of death in bowling and golf. Have you heard of bowling alleys or golf courses going out of operation because a customer had a heart attack?

The maddening thing about these studies is that after testing the individuals regularly while they were diving, they waited 24 hours to do the testing before flying. they found all of them to be bubble free at 24 hours. Why didn't they test them at the 18 hour mark, which is when DAN Americas...

The typical ScubaBoard BP/W solution works well here. I will offer slightly different advice. I have exactly what some people have advised--an aluminum backplate for travel and a steel for colder water, but you obviously want to start with only one. That makes sense. In that case, get an...

What a lot of people do during these discussions is make references to recent research to support their positions. Many people find that more effective than simply insulting the people who are disagreeing with you.

In a webinar about neutral buoyancy instruction about 3 years ago, Mark Powell said SDI now requires all OW instructors to teach that way. I don't believe that is true, but that is what he said. PADI does not require it, but it promotes it. It requires some skills be taught that way in...

I don't want to push this--I was mostly just adding to my continuing crusade to change the way scuba was traditionally thought, but I will comment on this specific sentence, because I have seen its equivalent many times in arguments about why instructors don't change. Let's give it a closer look...

Ask the instructor if the skills will be taught while you are kneeling on the floor while negatively buoyant or horizontal and neutrally buoyant. The difference in the kind of diver you will be at the end of the pool sessions is huge. If taught while neutrally buoyant, you will look and act like...

Back when I was training with UTD, I was specifically (and emphatically) told that computers can make mistakes, that is why it is better to use "the computer between the ears," which does not.

There is math you need to be able to do, and there is math you don't need to do. Back in my own "ratio deco only" stage of diving, two friends got mildly bent on a T1 deco dive. One of them was using a computer in gauge mode as a bottom timer, so he was able to produce a dive profile showing...
