If it was not intended to be taken literally, why did you work so hard to defend it?

I spent a while trying to figure out how this makes any sense, but I gave up.

And, according to you, these former students with the terrible skills are still better divers than the instructors who taught them.

I'd typically be doing more than 10 minutes of deco and also more than a 1 hour surface interval.

Why would you make that assumption? Are you talking about test conditions or simply by the dives people have been doing for decades?

It depends upon how serious the first deco dive. I have frequently done more than one decompression dive in a day. There are lots of shallower depth decompression dives that can easily be repeated in a day. When teaching technical diving, it is almost necessary if you want to complete the class...

Like Ron Goodman, I do my single tank diving with a BP/W and a single tank adaptor. I own an aluminum plate, a steel plate, single tanks, and double tanks. Having the STA allows me to mix and match easily. I have never experienced anything like the sloppy feeling described earlier. I assume that...

My wife and I go on dive trips with another couple annually, and for our bigger trips to the Pacific we always use a highly experienced local dive travel agent. In fact, as I type she is working on options for next year's trip, which might be to Raja Ampat or the Philippines, depending upon what...

Yes, and that sort of thing can explain the undeniable fact that the older people are more likely to die on a dive than younger people. The question raised in this thread that is more problematic is the question of whether DCS is more likely to occur in older people. DCS is a cause of death in...

As an older diver myself, I think a relationship between age and DCS would be related to circulation issues that can arise as we age. The flow of blood through the tissues is a key factor in both on-gassing and off-gassing.

I have written about this in other threads. The problem here is that you are writing "instructor/dive centre," implying they are in essence a single entity. They are not. The dive centre controls the conditions of employment for the dive instructor, and the two often have conflicting beliefs...

Well, here's another thing you don't know a whole lot about. The PADI RDP was not based on the US Navy tables. Far from it. The PADI RDP was created after extensive research on hundreds of divers using doppler bubble imaging. Their work led to many publications in scientific journals. One of...

Wow! The goal posts have certainly moved! I believe that some instructors are outstanding, most are competent, and some should not be instructing. I believe all of them are qualified as open water divers, and I don't know how else to define that other than saying they would pass the OW course...

So you believe that it is literally true that the majority of dive professionals would not qualify to pass an introductory OW class?

If something were to go wrong in a dive on which you are assisting and there is a subsequent lawsuit, you would not have the liability protection that comes with professional status. I am a retired instructor, and I will not assist a class.

When you make patently absurd comments like this, it makes it hard to give any credibility to anything else you might say.

I will first describe an incident that has nothing to do with this case and then use it to make what I hope is a point related to the current discussion. Years ago, I met a divemaster in Mexico who told me of this local incident. An instructor had a class of 8 students, and the shop used a DM...

Personal opinion follows I don't think he really believes anything he is writing in the last few pages. What characterizes his most recent posts is that they are all personal opinion (difficulty of learning materials for new divers), and the only response to those personal opinions is personal...

Isn't this true of all computers? My first computer was a Suunto. The manual was a nightmare to understand.

I know people who have dived for years with A-FIB with the full approval of dive-savvy cardiologists.
