TDI ADV Nitrox & Deco Procedures.

[battles2a5]

If you are considering taking these classes then you are at the very beginning of the road for tech diving. There is a world of diving that you can/should do on OC before the benefits of CCR begin to make sense, IMO. Not to mention you need a lot of experience to deal with the complexities and inherent risks of CC. I'm just finishing up Advanced Nitrox/Deco and I am having too much fun with this stuff to move to CC just yet. When I get settled in w/ running decompression dives, I'll add He to the mix. When I get comfortable with that, I'll go to full mix. And then, if my diving demands it, I'll go closed circuit. The way I see it, CCR is a means to an end and I'll only go there when the limits of my diving justify it. Either way, have fun w/ the courses. Those classes are lots of fun.

I also have a different opinion..

As for the price factor, there are many variations depending on where you are located. However, the higher travel cost and HE price are, the more CCR is attractive in the market.

First of all, it isn’t common to charge a gas fill per CF except a couple of tech friendly locations.
Second, unless you have your own fill station, the travel cost is another huge factor as the fuel cost and time cost goes up. For example, there is no HE availability in my region. I had to drive up 3hrs and waited for 4 hrs to fill even 32% nitrox on three doubles.
Third, once you build your own fill station, the maintenance cost is another big factor. There is an endless list to follow on this part.


I am NOT arguing CCR is way to go at this moment. However, as for the price wise, CCR is getting more attractive. It is also common to hear from many advanced/hard core OC divers that they could have bought any CCR if they sum up all OC gear including a fill station that they have. I have to agree with this point. I should have bought CCR.

75 dives are a lot? I guess you made more 75 dives per year, didn’t you?

Just my 2bar.

Man I would have to disagree with you. There are alot of benefits to CCR, more bottom time, carry less gas, no bubbles. Yeah CCR's are expensive but so is top of the line OC gear.
If you can spend 3k on gear and training, I'd like to know where you shop and what book your reading.

Hold on Chad, re-read my comments..... there are many advantages to CCR, but going that route for the sake of saving money on He fills in my opinion is not the right thing to do...

 

[Meng_Tze]

75 dives are a lot? I guess you made more 75 dives per year, didn’t you?

Re-read my comments... I was only focussing on going CCR for the sake of saving money on mix


Yes I did do more than 75 dives, but not all on mix.....

 

[The Chad]

I know man I'm just giving you a hard time. I do wanna know where you find all that training and gear though for $3000. Like someone already said, I could have went the ccr route for what I spent in OC stuff. Plus getting fills with dbls can be a drag in most areas...nothing like lugging 3 sets of dbls 350 miles from home just to make 3 dives

 

[Robert Thompson]

The cost of He should not be the reason to go CCR. You'll be disappointed if that is the main focus. CCR diving is inherently expensive. Take an average CCR of what: $8000,-, plus all bits and bobs, then you have training at say $2000. consumables, services etc, etc. I figure you spend about 12K at the best before you dive a ccr on mix.

OC mix training and equipment will be around $3000 if at all that high. So ball park figure 9K difference. At $120/OC fill you are looking at a minimum of 75 mix dives before a RB breaks even...that is a lot.

You have to figure out how many times you will need mix for a dive and if the risk is worth it.


(caveat this with the fact that I am just getting into CCR and do not have all the numbers worked out yet).

Depends on the CCR, Kiss Sports start at 4500.00 Classics at 5500.00 training is actually about 1500.00. Yes its still more expensive but not that much more expensive, and if you already know you want to go rebreather it does not make sense to spend 2000.00 on certs that you will have to do over again on CCR. You do however need to make sure you are a maticulous diver when it comes to pre dive checks, diving protocol and maintenance on your rig. They definitely don't forgive as well as OC. If you make a silly mistake like oh I forgot to turn on my electronics or my O2 valve it could cost you your life. Not to be grim but its true.

.. training is actually about 1500.00. ..

you can get ccr mix certified for 1500? that is MOD2 or 3 right?

 

[Warren_L]

I think Mod 2 cost me about $1000 in course fees. Other expenses like gas and travel were not included.

 

[Robert Thompson]

No, you can get CCR qualified for Air for between 1000.00 and 1500.00. Normoxic and Hypoxic trimix obviously is more. And there is alot of diving required between those courses as well.

Yeah Robert I understand. I am a comercial diver so I understand and practice check lists before every dive. Thanks for your information!
