    Ground hog day.

  2. Guns & Jordan 1’s says

    This was a lot better then the PADI e course thanks

  3. Shrek Xd says


  4. SV methos scuba and sail says

    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?

  5. Nicolas Lalire says

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

  6. Linda Rawlins says

    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.

  7. MayaWBAIS says

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

  8. Josip Živković says


  9. XFERD says

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

  10. Iam Sir Z says

    am I stupid ???

  11. Richard Turner says

    This guy is great! Dive Tables simplified.

  12. Delta Stegeman says

    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.

  13. Anthony Giampaglia says

    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!

  14. chaosawaits says

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

  15. MrWolfsack says


  16. Rick Kinney says

    This all makes sense to me.

  17. Jerry Mercado says

    Easiest advise. Never dive twice in one day.

  18. Jessica Lee says

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

  19. Glenn McLeish says

    Thanks!! That is a great explanation.

  20. Sir Uberlord says


  21. 3593893 says

    Good job here.

  22. Jonathan Ziebarth says

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

  23. Gary Cotz says

    Excellent, super presentation based on the chart.

  24. tousant558 says

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

  25. Thomas Blackwood says

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

  26. Sameer Shah says

    Very informative. Thanks.

  27. Renee11123 says

    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.

  28. C K Khoo says

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

  29. Groundhog says

    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.

  30. djjoshua007 says

    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

  31. Landon the savage says

    How did u get 30 as your actual bottom time

  32. Mark Hammer says

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

  33. T J says

    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…

  34. Mathilde McBernick says

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

  35. Mammy Slothy says

    i got the bends just watching this guy. helpfull though

  36. PF68 says

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

  37. John Stanfill says

    Incredibly helpful

  38. IceCat says


  39. southcoastskate says

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

  40. David Yee says

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

  41. Christine Tinberg says

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

  42. Eric says

    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.

  43. Jeff Pettigrew says

    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

  44. Carlos Aguilar says

    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.

  45. FULL Throttle45 says

    great explanation.

  46. Christian Schiebold says

    Why is he not using table 3?!?!
