Mark Powell: Intro to Deco Theory & Deep Stops

Back by popular demand, Mark joins us again in our virtual classroom for his encore event 'Intro to Deco Theory and Deep Stops'! See Mark break down the key concepts of decompression theory and discuss the latest research and discourse surrounding deep stops.
For those who don’t know him, Mark Powell is a TDI Instructor Trainer and TDI/ SDI International Business Manager, Member of the TDI Training Advisory Panel, Founder of Dive-Tech, Public Speaker and Author of ‘Deco for Divers’; one of the most popular and essential technical diving books worldwide.

Amazing presentation. Now i finally understand the purpose of the 16 tissues in ZH-L16! Thank you very much 😊

[@buslu]

This is a great talk. Thank you Mark and Thank you Dive Spear and Sport. I believe this is the second time I've listened to this webinar, and probably won't be the last time.

[@MisterTonton1]

I am an engineer and a tek beginner. I understand you 💯%. All those over confient Divers trying to explain me failed miserably. Thank you Sir. We feel the passion.

Finally someone made it make sense to me. I've read so many articles and watched videos etc... Very good job at painting the big picture!

[@jadefalcon001]

This was hugely educational. Thank you so much for sharing it! This has given me a much greater appreciation for what's going on inside my computers' models.

thank you for the upload. great talk/class. hypothetical question: if blood is whats caring gas into the tissues, blood transfusion/dialisis or some of the sorts could help with serious cases of DCS?

[@michaelmuir4548]

Great explanation thank you. Seen Mark at the UK shows several times and have the book. Always interesting.

24:41 Critical supersaturation.

Thank you a lot for the excelent explanation, it helped a lot in understanding the logic behind deep stop.

[@josemanuelcarvalho6413]

Excellent tutorial Drº Powell, already read your "deco for divers "book and really helped understanding Deco theory. Thank you very much.

[@timverkoyen8742]

This is so interesting and informative. Thank you!!!

[@CorrupteddSanity]

Thank you for posting this

[@RichardSlater]

Really enjoyed this.

[@atalomaniac]

Thank you very much, really informative.

[@mustanggun]

Thank you for posting this video. This video cleared up a few things for me. Safe diving mi amigos.

[@paulknight89]

Great webinar, made decompression look easy.

[@vitkasal950]

Great webinar, but made deco look like blind shooting to me

[@tabchief]

Helpful video

I don't understand why the M Value blue line is not parallel to the green Ambient Pressure Line. As with the example of a tissue with a 2 bar limit for the M value, there should be a constant difference between the blue and green lines, which implies parallelism. If not, as it is shown, it implies that the M value can increase with depth. Can you explain? Regards.

Very educational for me! One question: with ‘standard’ GF’s were are more conservative at depth. Why? Why not use 70/70 for instance?
Thank you!

It's too rigid, not enough flexibility to serve a wide enough range for different body types and fitness levels.

[@diveaddict6885]

I use a Shearwater GF 40/85

The first graph is actually a logarithmic function.

Good subject and with lots of potential. But certainly the presenter misses some fundamental definitions from a thermodynamics, and physics stand point. Saturation vs. Supersaturation definitions are very, very weird. Where do you come with those definitions from. This is all physical-chemestry dynamics. Nothing exuberant. Very straight forward. You are talking about gas solubility in solutions or tissues at contant temperature (body temperature) and while pressure variation. There are more easy ways to explain this principle. You are all over the place with it. In fact, your visuals are kind of confusing
As I said, there is tremendous potential for this subject. Thank you anyway.

You should produce a video to correct his errors .

How many books have you written on decompression theory?
