Rebreather Training Progression?

Ben Field

Hi All,

Been diving the SK for a year now, starting to look at "where next" qualification wise... this is where I'm confused.
(Rebreather wise I already have a plan )

Mod 1 was the obvious, necessary place to start so I didn't bother looking into the requirements before hand, just choose my instructor and went for it :-) (Thanks Dave)

Neither TDI or IANTD have details on their websites of the requirements for Mod 2 and 3. Anyone know the pre-requisites for those courses and what they lead to? Also what "level" do i need to be at to progress, want to do Trimix eventually (Yes I know SK won't go there but lets forget that for now)

(I've been assuming Mod 2 is like Tech Nitrox and Mod 3 is like Trimix?)

Thanks,
BEN

Ben,

For the SK, you could do mod-2 and forget about mod-3. And I am referring to Normoxic Trimix as mod-2 in my context.

It has been discussed on various threads here. Jetsam spec'ed the max depth for the unit shallower than the depth you need to dive for mod-3 course.

Since I had a couple of SK students REALLY want to do mod-3 course, I begged and pleaded with Jetsam to increase the max depth by 5m so they could officially complete the IANTD mod-3 cert. Gordon (this was last year) didn't want to increase it then, so they only did mod-2.

May be Kim will reconsider now, but I haven't asked since...

ADDited:

Since you are a OC Trimix diver, I recommend to go directly to mod-3 with another unit rated for deeper official range than the SK. Of course, you would have to do a x-over to the new unit, and put hours in beforehand.

You guys are not a million miles from what I was thinking....

I have a buddy with a CK and I'm now rather familiar with it, also I have a Shearwater so the upgrade path to the CK is pretty clear.

Phi- are you saying OC Trimix cert would allow me to jump to Mod 3? I still slightly don't understand the "mod" structure, why aren't they called- Recreational Rebreather Diver, Extended Range RB Diver and Trimix RB diver instead? :-)

DAVE- PM sent.

This is copied from the IANTD standards prerequisites for CCR Trimix Rebreather course:

A. Prerequisites

1. Must be qualified as an IANTD Rebreather Diver, or if entering the Program based on equivalent experience, must be qualified as either Normoxic Trimix Diver or Trimix Diver (OC) or must be taking the Normoxic Trimix Diver and Trimix Diver course on an approved Rebreather for mixed gas diving, with all dives other than confined water made on Trimix or Heliox.

2. Must provide proof of a minimum of 200 logged dives or sufficient experience doing technical dives to satisfy the instructor that the student has the ability and knowledge to continue into this level of training.

3. At least 50 of which were on the specific Rebreather to be trained for.

4. Must be a minimum of 18 years of age.

I don't understand the Mod thing either. IANTD has CCR Diver, Normoxic CCR and CCR Trimix. TDI Has Air Diluent, Mixed gas and Advanced mixed gas. But neither will let you do full mix on a SK due to manufactures rating.

Sorry, I re-arranged your reply a bit here to ask my questions...

1. Is TDI mixed gas (2nd course) involves normoxic diluent ?
2. If so, then I think both systems are relatively the same. Yes ?
3. If all above is correct, then I think we could summarize:

• mod-1: CCR Diver = Air diluent
• mod-2: Normoxic CCR = Mixed gas
• mod-3: CCR Trimix = Advanced mixed gas

Looks OK ?

But what are the entry requirements?

It seems somewhat simpler for those who were already OC trimix qualified ie just head to MOD3 on a suitable unit. What about those of us who never progressed to trimix on OC?

I'm looking at doing a normoxic trimix course basically because I feel an awful lot more narked on CCR than OC at 40m. Not to bad in blue water but in the dark with crappy vis it's not nice.

Problem is I can't find the course requirements anywhere?

Regards,

Mary

IANTD has their standards on their website that you could download to review everything including:

• prerequisite
• exercises

for each of their courses. And within each course, the differences of what is required depending on the background.

Any idea how the TDI requirements differ?
