Pressure groups explained

Rating: 4.77

Having learned to dive late in life I made up for it in my first year by clocking up 120+ open water dives in places from the UK to Australia. I went from a non diver to a technical deco diver in 9 months and loved every second of it. Since having kids not been able to travel as much so spend my time watching videos and reminiscing, hope you enjoy my site as much as I have making it.

Ground hog day.

This was a lot better then the PADI e course thanks

Thx

Hey im having a issue on calculating on my padi exam.

Wants me to do 17 meter depth but it skips it. Was told to round up so it put 18 meters instead no?

did he just planned a 50 feet dive AFTER a 40 feet dive ???

This is a good shortcut to keeping up with residual nitrogen, but it may be missing an important factor, which is maximum allowable bottom time for your next dive (the planning part of these tables). That is given to you on Table 3, which isn't mentioned in this presentation.

What if your depth was below 35 and your time was below the lowest number?

Cool

EXCELLENT EXPLAINATION…

thanks for this vid..didn't remember the tables…you made it easy

am I stupid ???

This guy is great! Dive Tables simplified.

HOLY SHIT, THANK YOU SOOO MUCH. I was so confused in the middle of one of my training exams because I didn't understand how the dive tables worked. THIS IS SO HELPFUL.

Super helpful. I took a PADI class years ago and ended up failing this portion of the test but u explained it much better than my instructor did at the time. I think I’ll have a better chance at passing next time I go thank u!

Why does residual nitrogen become less the deeper you dive? Shouldn't it be the other way around?

Adrian!!!!!!

This all makes sense to me.

Easiest advise. Never dive twice in one day.

Now I'm even more confused than when I first looked at the table

Thanks!! That is a great explanation.

THIS IS INCORRECT – THE RESIDUAL NITROGEN IS CALCULATED USING TABLE 3 – NOT BY RE_USING TABLE 1!!!

Good job here.

Your wrong, you didn’t follow what was clearly labeled on the chart. Which was to continue on to the other side

Excellent, super presentation based on the chart.

really great many many thanks, much easier explained than in class, got test on sat 🙂

Very clear – I start class in 3 weeks! Great primer. Clear and good examples. Many thanks!

Very informative. Thanks.

Very helpful! I was reading the book I got for my course and was still confused. This video helped me understand the tables to where I'm confident in moving forward.

A very good explanation, especially on RNT. Not flipping the chart over made it very clear

Ok – you may know what you are talking about but to a person (me) looking at taking beginners PADI? This meant absolutely nothing to me. You failed to explain the knowledge you have internally 'what you was about to teach' externally that would have explained what on earth you was talking about. You too did not explain what the chart is for or how to use it very clearly – just rushed your way through.

I understand why this is confusing to some it so you did not go into decompression on multiple dives or it’s to work out some sort of question on a Padi test

How did u get 30 as your actual bottom time

This is so much easier than I have ever been shown.

You did a dive at 40' then 50' with a SI of 2 hrs and your RN is 13?? Are you not supposed to plan your deepest dives first? Just asking…

Thanks you a lot !! So helpfull for my divemaster final exam

i got the bends just watching this guy. helpfull though

well ok I see how to work it out but you didn't explain what it all means and why it works

Incredibly helpful

Thanks!

Excellently put across thanks for that.- Been diving years but still have to revise this every year I go ..lol ..

Congratulations! One of the best videos I'd seen to explain how to calculate multiple dives using the PADI Dive Tables.

Talked way too fast Needs to slow down and explain the theory behind the tables more thoroughly.

This is clearly wrong !!!!!! E is the residual Nitrogen according to the instructor, and to find how much we have we look along the 'E' horizontal line. Thus the DEEPER we go the LESS residual Nitrogen we have ie at 60ft it is 17 and at 90 ft it is 11……. how does that work? This Video should be removed, it is dangerous.

He did not show you the CORRECT way to use the RDP for a repetitive dive since he NEVER flipped the card over to show table 3, which is where you actually find the RNT (residual nitrogen time). Also without flipping over, he will not

know his ABT (actual bottom time) limit. So he did not plan his second dive, as he does not know what his max time limit will be. He just showed you how to answer a test question. Lucky his values did not require a mandatory deco stop for staying down to long as he NEVER shows you the legend

Your presentation of dive tables is terrible. You haven't explained what the tables are for, how to read the tables, or where the legends are… you haven't taught a diver about decompression theory rather how to answer a question on a PADI final exam.

great explanation.

Why is he not using table 3?!?!
