How long until?

[MicahEW]

What can I do with with a diving cert+EANx?? What should be the next class I take? I am thinking of AOW or rescue.

[cummings66]

As I understand your wishes, you want to be a technical diver. So, your progression will be from AOW to Rescue to Deep Diver to Advanced Nitrol/Deco to Trimix to maybe rebreathers.

What can you do?

What do you want to do is the real question.

Using EAN for diving will allow you to have a lower nitrogen intake which means you can do a few things with it depending on depth. You can either extend your bottom times or take the reduced loading as a safety factor. The deeper you go the less benefit it has and the shorter the time it really gives you. There are other claims such as feeling better, shorter SI times as well. Probably others too, the main usage seems to be extended bottom times.

What cummings66 said.

There is a very simple answer to diving with OW + EANx: Dive!!!!! Dive!!!! and then Dive!!!!

As C66 said, Nitrox can increase your safety margin if used with recreational air tables-less nitrogen exposure = increased safety. It can also extend bottom time by dropping your "Equivilent Air depth" i.e. using a 32% EAN, a dive to 75' has a NDL of 55 minutes instead of 30 minutes using Air (21% EAN)

What ever the case, Go diving!!!

If your target in the future is something like PADI Deep Tec, you will need to have a good number of dives; 100 divies minimum with 20 being Nitrox, 25 deeper than 60'/18m and 15 dives deeper then 100'/30m.

So your final targets shold be: AOW, Rescue, Deep, Nitrox (Enriched Air) and probably Dry Suit as most Deep Tec use a dry suit due to long down times-Bottom times and Deco Times).

Pretty much what the two said.

Thanks guys I was wondering the steps/ progression is training like what to do next. so AOW should go before Rescue?? then Deep?
Its great to always get feedback from ya'll.

[cummings66]

Most agencies require AOW before rescue. Electives can be done in any order, but the real deep diving tech classes will require rescue before they can be done.

IMO don't dive deep until you know how to plan a dive to that depth safely and not just wing it. Deep for the sake of being deep is stupid, always plan for the dive and have ways out of failures.

Speaking of diving, how's your OW stuff coming? I haven't heard you post about that in a long time now.

[MicahEW]

I went and signed up for the class it is in April I was going to do it last time I posted but this lovely TN weather had mi sinuses messed up. I have always been told never to take allergy/sinus/cold meds bofore a dive any input? What do they teach in AOW vs OW?

[cummings66]

They will never tell you to dive with problems. The party line is, if you need medicine to make it through the day, then you don't need to be diving.

Many people with allergies use those meds though, but you do need to be careful with some of them because they can adversely affect a diver. Call DAN if you have questions and you're on them, they'll tell you what they know.

OP...

I have constant congestion issues throught the year...it SUCKS! I also have E-tubes smaller than a human hair I think,,,so 'descending' is always a bit of a slow task for me on most dives-again it SUCKS! Use over the counter meds or Rx's by following directions and Dr.'s instructions.....use good common sense. I have over the years learned to deal with these less than perfect issues when it comes to diving...so it can be done. But their are folks that just find it to difficult to safely dive from cronic congestion problems, you will know if that apply to you....I have had to abort only a few dive outs so I feel blessed. Good luck!

[rox@ucf11]

yep I take sudafed before every dive because I have troubles equalizing, if I am congested on top of that I dont dive
