Deco Stops

[gehadoski]

Hi all
I am asking about deco stops and how we were calculating them without computer? I used to know that rule but I have been using computers for a long time and I moved so I don't have my maniuals with me. If you can remind me about that I will be thankful.

Use tables which include deco stops? (as are the ones I use).

If you no longer have a set of decompression tables you will obviously need to get some. It would probably be best to get whatever the type of table was that you used for your course. Whatever tables you get DO NOT use them unless you are ABSOLUTELY sure how to use them properly.

Also be aware that most tables (except for the RGBM tables) do not include deep deco stops. Most advanced divers and decompression experts recommend stops much deeper than traditional tables would give.

Decompression diving should only be done if you have completed a proper decompression course. If you are not experienced in decompression diving there is a lot more to it than simply jumping in, swimming around on the bottom and then doing some stops on the way up!!

GUE has an on-the-fly method that they used to discuss in their advanced tech courses. I cannot speak for them, nor would I want to. If you are interested in an on-the-fly approach like that, I would high recommend the following:

1) Find a GUE tech instructor

2) Get the right gear that the GUE instructor is comfortable with you having

3) Take the DIRF, Tech 1, and Tech 2 etc courses

4) Obtain the proper deco gear. Normally this involves double manifolded tanks, and 2 or more additional stage tanks.

DO NOT DECO DIVE until you have followed that training program.

I do not know of any other tech agencies that teach on-the-fly deco. NAUI and TDI use deco tables. NAUI's tables are RGBM with pure O2 for the final 20 and 10 ft stops. TDI uses EAN80 and EAN36 for the deco portion of the dive.

ANDI and IANTD also have their own deco procedures, which you can find out more about by speaking with one of their tech instructors.

GEHAD-OWSKI are you for real? Last time you were asking about rebreathers. Don't go into deco. That for you would be a one-way trip.

Gosh! I remember diving in the 70's with the old Scubapro Decompression meter. Mine had only 4 digits-an early one. Now, I've heard people call them the "bend-o-matic, but I take exception. I spent a lot of time diving in decompression along with many of my fellow divers doing deep dives or cave dives. I never knew anyone bent on a meter that was kept calibrated (as all of ours were). I did very risky diving that I would not do today. I was very careful, and never suffered ill effects (knock on wood). The basic training, in those days, covered decompression long and hard. Now, you have to pay to get "certified" to do it. Yes, techniques have changed and so have I.

Wow!! I can't believe that someone who was diving that long ago, and with an "early bend-o-matic" no less, is still alive!!! :11:

I did OW and AOW certifications in 1985 with "old school" instructors in college courses with a lot of time to fill. Deco procedures were covered in great detail as were the knowledge and application of various gas laws. I left with the impression everyone got this training and demonstrated this level of ability by the end of their AOW. This was in reality no longer the case even then.

The dumbing down of OW and AOW training and the lowering of the physical and practical standards has opened up diving to many more individuals, but it has substantially lowered the stardard of proficency displayed by new divers and this is not a good thing.

I couldn't agree more! I was, recently, royally flamed when I suggested that this "dumbing down" of the standards has seriously compromised new divers who really believe that they have received quality education for their basic (and AOW, for that matter) certification.

I got OW certified in 85 as well.
I was wondering why so many people had problems with bouyancy till I stumbled on my OW logs last night. Every dive I did in training was graded on ALL of the skills, EVERY time (college class too). I looked at the new standards, holy crap, most of it is a joke. Nobody is required to have any real skills.
I wish I could help on the deco thing, but I'm just startind down that road. GUE- DIRf this summer and Rec Triox next. That's the way I am going, but not everyone subscribes to that way of diving.
Good luck.....
