MOD2 & MOD3 Course Content

[Gareth J]

Hi All

I am intending to do my MOD2 & possibly my MOD3 in the new year.

Does anyone know where I can have a look at the course content, i.e. what is supposed to be covered in the theory. what is supposed to be covered on the practical dives & exercises.

I am OC Full trimix qualifed, & a blender, so could, just blend & dive my own mixes, but I do want to learn something on the next course. I also want to have my CCR skills given a good going over.

I am not interested in a turnup & qualify ticket, if I am going to spend good money (& time), I want to ensure that I have got something back from the course.

I also want to ensure that I have developed & practiced the skills in advance of the course, so that we are not wasting time on remedial work!

I know that Mark Chase always moans about this ! The theory book was/is the same for oc or ccr .Mark said he was totally p***ed off that he had to pay money to basically do the course again (from oc to ccr).Can you not talk to your instructor from oc trimix or does he not teach ccr ? Otherwise talk to matt robinson ,M R DIVING Midlands Rebreather Diving on here as desperation99
I know he teachs trimix ccr & have heard a lot of good recomendations for him
good luck

With an OC mix ticket you can go straight to MOD3, no need to waste money on MOD2. The standards are available online, I did IANTD MOD3 with Martin Robson, an enjoyable course but I didn't learn much new.

Yep CCR is the same as OC with a few bail out drills.

Really naffing annoying having to pay more money to do the same thing.

Can ask a stupid question?

As the OC and CCR trimix courses are so similar, does the CCR qualify you to use OC? or should you get OC trimix first?

I am asking because I was looking to do a trimix ticket, then decided to buy a YBOD instead, with the intention of going MOD1/2/3 in due course.

The perverse thought struck me, that in the event of a bail out, I would be using OC gear beyond my OC quals.

Thoughts please.

You will be taught to plan your bailout at the worst possible point, ie end of deepest portion of CC dive, this will give you the planning to bail out and deco on OC.

Hi folks

The above is very interesting.

I (myslelf and buddy) are moving dive clubs and was talking to the DO of the new club last night.

I am currenty OC trimix qualified and CCR (air dil) qualified, but almost always dive the CCR these days and almost always on Trimix, from Capernwray down to about 60 (ish) meters. ( I only have 1 dil clyinder and why not anyway its a nicer dive and the cost is so low anyway)

However this gives the DO a problem as on paper I am not CCR trimix qualified and theirfor should not use on club dives. He has said to use trimix as a dil I must get CCR trimix qualified!!. I understand his point as he has some responcability for the club diving but as already said a £500-£600 course is a big cost for a course where most of what will be covered I already know.

As this looks to be a common problem is their any scope for a cross over type course ??.

Hi Gary, there was an article on rebreatherword the other day about this, if you are O/C advanced trimix you can use normoxic mix in the unit.

Have a search for it, may save you some money, because you will only be putting normoxic in any way wont you

I think the IANTD course allows you to use mix after 25 hours on the unit if you were mix qualified previously. You are limited to the Advanced Recreational Trimix limits (ie 40m max).

I understand your DO's reaction. Even the most sensible of DOs is going to have a little worry if a couple of people approach hime and tell him that they're doing something that's outside their certified limits. Not to mention he might worry about covering his own arse from a liability point of view. If you're qualified with IANTD then hopefully that should be ok.

Trimix is great, and I now dive 18/52 for everything. Even in puddles as it's generally cheaper for me to put 50 bar of mix in then it is to drain the cylinder after putting air in.

PS - I really enjoyed my MOD2, and found it really worth while. I would consider doing your MOD2/3. Go abroad and make a holiday of it.

hi james

thats my understanding of it as well, you can be mod 3 trained down to 100m and trained to carry bailout for the depth, but not to dive oc trimix, but correct me if i'm missing something, if you are bailing out on oc during mod 3 then like james has said why do you have to get a oc card as well for trimix
