    Thanks from Australia

    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.

    This is a GREAT video to show how to use a dive table. Watch his part 102, 103 and 104 to get more details on how to calculate dive times and no decompression limits. Exactly what everybody wants, it’s just in different videos. Love this!!!

    Nice simple explanation. Got certified as a kid back in the 70's and have recently gotten back into it. Was trying to understand the old dive tables and this brought it right back to me. With everyone using computers seems like no one cares about dive tables anymore which is a shame.

  • @webberyt7893
    @webberyt7893 7 років тому +92

    This video is helpful but also problematic. It helpfully simplifies the tables by pointing out that, in Table 3 (which is not referenced), the Residual Nitrogen Time (RNT) after surface interval equals the maximum time allowed for a particular pressure group on Table 1. But this instructor computes the Total Bottom Time for a repetitive dive by adding the RNT to an already performed Actual Bottom Time (ABT). That's fine if the ABT has not exceeded the allowable no-decompression time, but the instructor does not show how to use Table 3 in advance for planning a repetitive dive. He only calculates ABT after a repetitive dive. If you haven't consulted Table 3, you don't know the time limit for ABT. So the math works out, but he has not shown how to plan a safe no-decompression repetitive dive.

    • @631gal

    • @neelufisherman
      @neelufisherman 5 років тому +1

      I have been a commercial diver for the last 33 years and come across numerous incidents on DCS.The USN Tables are the basis of PADI but over the years USN tables have been made safer with Revision 6 in practice now.Its a know factor that chances of decompression increases with repetitive dives.The number of Decompression incidents are increasing as sports divers try to get deeper using dive computers and rebreathers and Trimix the very essence of diving for pleasure goes away when u have a fatality.As a person who spent thousands of hours underwater i approach SCUBA with uttermost caution.I am sure people reading stuff like this on decompression will assume you can keep repetitive dives.A good approach is to plan your dive have a clear picture of your bottom time ,deco obligation and also a back up when all else fails.A good video all you sports divers is this no hollwood stuff real men real danger. ua-cam.com/video/9dG5KSD-8J4/v-deo.html

    The numbers across from the Vertical Pressure Group are the minutes not the "amount of residual nitrogen"

    • @DavidMaruca_
      @DavidMaruca_ 6 років тому +2

      Correct, but the amount of residual nitrogen is represented by the pressure group letter, and you use the time noted by that pressure group at that depth to tell you how long to calculate for. It's letting the diver focus on the time rather than the ppm of dissolved nitrogen in the body.

I've had dive shop owners compliment on the way I teach. When it comes to the tables, I make learning them easy, and understandable. SIMPLY because I follow the rules, and don't think I'm better than the Organization we all are members of.

  • @scubamarcos2993
    @scubamarcos2993 12 років тому

    . Put your finger on E and slide it across to the depth you plan to dive next. E at 60 feet =17, E at 90 feet =11, E at 35 feet =32 minutes of residual nitrogen. The only time you need to turn it over is when you're looking up your pressure group to determine your minimum surface interval.

    Hello sir;
    Really interesting class, I am about to take the Scuba dive this weekend, at first seeing little confusing but now I got to understand the procedures of the Scuba Table. Anyways, the whole thing here is to make sure that if I'm going to scuba dive, I have to maintain with the dive group to make sure how much residue of nitrogen still in our body. What we want here is to no to have nitrogen residue in our body right? thanks sir.

    table 3 shows you residual nitrogen time and adjusted no decompression limit..(RNT and ANDL) for repetitive dives. Actual bottom time (ABT) is what your "actual" dive time is and it is not to exceed your ANDL.

    @scubamarcos2993 12 років тому

    Your pressure group and residual nitrogen may both be found on the front. For example If you made a dive to 35 feet for 85 minutes you would be in Pressure group P, after an hour surface interval you would be in Pressure group E. You may look up your residual nitrogen for any depth on the front of the dive table. The only time you need to turn it over is when you're looking up your pressure group to determine your minimum surface interval.

  • @smithersrob

    This is a very neat method, but would be improved with an explanation of how, using this method, to check your no decompression limits for the subsequent dive. It's not hard, you simply subtract your residual time for that depth from the standard No decompression limit for that depth. The method he uses runs the risk of someone doing the maths of adding their residual time to heir actual bottom of time at the end of a dive and accidentally discovering you just blew your no decompression limit.
