Brilliant video, thanks guys. I'm taking my divemaster exam this weekend.

Not everyone can hear what you're saying... i am hard of hearing and all these scuba reels does not helps without captions

Great video and tutorial. Thanks

Best explanation I've see, thank you!

would be more usefull to have not 100 kg and 100 liters of displacement, but 200 and 300 for example to understand better the example. 100 and 100 makes it a little bit confusing for learning.

Phenomenal!!👏

So helpful...appreciate all your videos!

Thanks very much for your video. And when I following your video and calculate a dive, I can’t find a correct answer, because the other Instructor said different. Can you help me to calculate this Question please?? “You are to use the Recreational Dive Planner Table or eRDPML: A diver is planning a series of 3 dives. Assume he will use minimum surface intervals, follow all Recreational Dive Planner rules and dive the following exact profiles: Dive 1 - 24 metres for 26 minutes; Dive 2 - 12 metres for 85 minutes; Dive 3 - 11 metres for 61 minutes. In minutes, approximately how long will the entire dive profile take to complete-from start to finish?” The answer I did was 425. The Instructor is 362.

The playlist for these DM skills is a 10

❤❤❤❤❤❤❤❤ Thank you for you explanations

Really? On their knees? Why not just have them do it at the surface if they're just going to kneel? smh

Regarding the lift bag question, how do you know if the object weighs more than 7kg? In reality, you can’t… despite the weight belt suggestion. In my opinion the question should be reconsidered by PADI. Anything you cannot pick up and stow easily needs a lift bag, right?

Could you please make efr video as well

Excellent explanation. Extremely helpful.

Thankyou for sharing this information ❤❤

Great explanation,. perfect refresher as I get ready to start IDC, thank you

the best explanation. )

What is a diver´s pressure group after a dive to 64 feet for 41min,? N,P,S,R?

Thank you for this amazing explanation. I´m only a humble owd and at a very beginning of my underwater journey. But thanks to you I got answers for a lot of questions I had. You rock!

Thanks so much for these!

this is the most helpfull chanel for scuba divers !!!

i love your videos . i am doing my IDC and my instructor is not very patient... im very i can find this kind of videos for help. thank you so much

Unfortunately being a dive instructor pays about nothing. Yes, you get to dive but your starving to death. Notice they never talk about this.

Perfectly executed.

🙏thank you

thank you^^ 感恩^^🎉

Are theses good to watch to help to be certified hyperbaric tech or could you refer to a different learning page. Thank you!

I dont understand whats mean residual nitrogen time in tab 3...

Thank you so much! Legit, you are the first person to explain this to me and actually have this make sens. Fingers crossed I pass the test 🤞.

These helped me during my dive master course. Thanks alot

Vrry helpful! Thankss

AWESOME!

I dive have for some years now and I'm always safety first really good video thank you for that I will make sure my dive people will see this

Phenomenal content! Idk where I should start, but regardless, great content! Thank you very much! 🙏

Gave up at 8secs as it’s in feet. Lol

Brilliant and very clear explanation!!

Hi, newly certified instructor here, I had a gap in my understanding of the half-times, compartments, m-values and surface interval credit, and your video series really helped me fill that gap. Thank you, this is all very clear now! One thing I am wondering though is why the tables were designed using a 60/120 minute gas washout tissue compartments intead of using the EE washout theory? If I understand well, the EE washout theory is a closer representation of the current nitrogen loading in each compartment, so why not using it in our models for surface interval calculation?

perfect !!!

you are amazing really , thank you bro i have IDC exam after month :)

this is an amazing video, you learned me in half an hour what I couldn’t understand even after reading it over and over again in hours!!

Mate this was great thank you

thank you!!!

Fu***** awful music

Thank you so much for all of these videos. I’m doing my IDC in August and these are so well done and helpful.

Very well done and helpful series.

Very well done 👍. If you get your tanks filled at altitude, would there be any difference in N2 and O2 ratios? Or is it still the same (just partial pressures are reduced), once tank is pressurized to 200bar it ends up the same. Thank you.

Well done. 👍 Thank you.

Great review! I’m a nurse that is a major respiratory system nerd and always love to reup my knowledge Tao thanks. Trying to get into diving rn. Wish I did it when I lived in Utila…. 😑
