FB posting - standards violations - how many can you pick out?

[Storker]

Not everyone who dives beyond 130 feet has taken the multitude of classes that the OP has taken is particularly lucid at those depths.

FTFY

Many of us have made hundreds of tech dives involving doubles, deco bottles, and mixed gas without a tech certification

Sure, but do all those of you (specific, plural "you") know enough and have the skills to handle a situation that has gone seriously sideways?

Usually, you (general "you") don't know what you don't know. Enough people have died winging it. That's why we have proper classes these days.

Anecdote time: I recently certified trimix blender. My professional background allowed me to wing nearly all of the curriculum, but I still learned a couple of things that might come in handy sometime. Which is another illustration that some humility might be appropriate.

That sure is a head scratcher. Not sure what TDI does about that. Maybe a TDI instructor can step in. @kensuf

Repetitive deco dives are not that big of a deal as long as the decompression obligations are not outrageous. NAUI standards are pretty clear, no more than a MAXIMUM of 15 minutes of planned decompression during a dive in a Tech Deco course. I usually have my students do a repetitive dive in AN/DP. We're talking about two dives to 130' with a bottom time of ~25 minutes each, giving about 10 minutes of deco and a minimum of a 90 minute surface interval in between dives. Remember, these are usually conducted on the final day of diving -- they worked up to the deco dives.

In a full cave class conducted in Florida, it's not unusual for every dive to involve deco ~10-15 minutes of deco. Two dives a day for four days adds to a bit of decompression stress, I always have my students pad an extra 5-10 minutes on the tail end of the last dive.

LOL,, yeah Max! You need to take one of those NAUI classes (to be safe).

BTW, I am a NAUI tech instructor as well.

What specific skills would those be that aren’t learned in thousands of OW non deco dives and practiced on a daily (or at least a dive daily) basis?

I did learn a number of effective ways to launch a DSMB, but I learned nothing in my admittedly abbreviated class that I didn’t already know and wasn’t already proficient at.
Now, for someone like Marie maybe, I don’t know her skill level, a class is useful in learning new skills. Someone “progressing up the ladder to” whatever their goal is. But (and this is a huge but) practicing skills learned is way more important than getting the next card.

I am lucky to have mentors maybe, and to have been in a position to be able to afford all of the toys that interested me, including a 100 foot dive boat. That gave me access to not only the famous tech divers, but many of the supremely competent ones as well. They aren’t all the same....

I don’t hold a hypoxic card, having a boat, booster, 6000 dives including 250 on helium and cash for helium seemed close enough. What I found is that I will likely never need to go to those depths again. It’s cold there. But the 6000 dives is what gave me the skills for the other 250, not some class.

No only do I need the additional skills training, I need the cards for the diving I want to do. I go off charters. No tech certs, no tech dives. Need them for fills here, too.

I know someone who went and got Trimix certified when his fills source (out of someone’s garage) went away when the compressor owner retired and moved away.

I really don't know.

This year I took CMAS 3* with some very competent instructors (GUE tech 2/cave 2 certified), and I like to believe I know what is required for what I'm certified for (light backgas deco and diving down to some 40m. Plus a few other things in that curriculum). I don't know what's good to know for more advanced diving than that, and I realize that I don't know that.

My original Open Water course through NAUI taught me how to dive to 40 meters. There is even a few paragraphs in the textbook about what to do if you go a few minutes into deco.

Many years later, I became dive buddies with a few friends who had been certified through IANTD and GUE Tech 1. They were more than willing to let me borrow their textbooks and to show me the ropes, including endless S-Drills. One of the benefits of having my own boat was lots of buddies who knew the location of deep wrecks and how to dive them.

I spent more money on boats, dive gear and underwater camera systems than I could have ever imagined I would earn in a lifetime. I could have spent that on classes, but then I couldn't afford to dive after that. Unfortunately, agencies are in the business to make a profit. Classes are broken into pre-requisites and into packages to generate additional income. I was able to learn what I needed to make the dives I made through the mentorship of friends. If I ever had the desire to cave dive or go to 600 feet, I can assure you I would take classes.

competent mentors are instructors (even if they don't have an instructor card ) learning skills is learning skills , if you read it in a book and think your competent ..then you deserve what you get
