Twinset/ Rebreather question.

[colinicky]

I went from diving a 15l single to twins for about 15 dives then said b****cks to this & went & did my rebreather course on a borrowed classic ,mainly to see if I liked it before shelling out lots of money .
If I had my time again I wouldn't bother with the twins but it is not for everyone ,we are all different .
The minimum dives when I did mine (18 months ago) was 100 under TDI .I actually did my 100th dive on the course ! On the back of my cert card it says that I am limited to 40metres with no more than 5minutes deco @ 6 metres .You do need advanced nitrox although this can be combined into the mod 1 ,but I would recommend doing it way before so you do not have to learn something else at the same time .
just my 2c

I was in a similar situation but already having dived twins for a few years, I would do a MOD 1 course with the breather/instructor of your choice using their stock, that's what I did and it helped me to decide that at the moment a unit of my own is not what I want.

It's a cheaper option than ordering one, waiting months for delivery then doing the course to finding out it's not for you.

Good luck with whichever path you choose.

Safe diving,
Steve

I went the conventional single twin set then CCR rout. I didn't consider CCR at the time I went twin set but after doing a fair bit of deco deep stuff on OC twin set i did feel it would give me an advantage if i had to bailout to OC deep no w I dive CCR.

Now after a couple of years on CCR I realize this is rubbish. These days when i go OC I am nervous as hell. You don't feel comfortable OC once your used to limitless gas diving. You start worrying about breathing rates and gas reserves. Its horrible.

So looking back on the past three years and my transition from OC to CCR My advice is if you can afford it go CCR immediately.

1 : you will develop far greater skills on the CCR than i did before going deep

2: it will save money in time and training

3; Ultimately CCR is the future of deep diving (past 50m) so get started on it now and don't waste time on OC.


An OC diver on our boat now is a limitation and a liabuility.

Feck me, l agree with Chasey.

l think the problem with doing the OC trimx route first is that people then rush to get back to do the diving they were doing before they bought the RB.

l wish l'd bought one years ago.

twin set , then side can + deco then maybe ccr

for get saving money or time . cant be done , not with diving its all time and money ,

Well that's exactly what I did and for me it was probably wrong.

As several people have said it's down to the reason you want to go diving.
My diving comes from my interest in Nautical Archaeology and that was taking me to deeper wrecks and longer stays and the twinset just doesn't cut it for that any more.

I would ignore the idea that twinset diving is an 'apprenticeship' we go through. It's just something you have to unlearn and more kit to clutter up your shed. CCR diving is different. You need to learn a lot of you procedures and re-practice them over again before commiting to them. Not having done them on OC doesn't really set you back so learn them in the way you want to use them.

Now I have a set gassed up and ready to go. If somebody rings up with the offer I can't refuse I can grab the kit and go. No worry about the mix for the depth, no worry about the deco plan, no worry about getting fills just go.

OK so then I'm seasick the whole trip and miss it all but that's a different matter.

[NotDeadYet]

I agree that in terms of skill it's an unnecessary step but in terms of diving common sense it is worthwhile. Spending some time doing twinset diving is a very good way of getting the right mindset for more advanced diving and it's much harder to get dead on a twinset if you f**k it up.

There is no skill that you can carry over from twinset diving that is particularly applicable to a rebreather but you have to weigh up whether or not you want to be cutting your teeth at depth on OC or CCR. At the very least, when a RB packs in, your an OC diver again so you better be comfortable at depth on OC.

CCR diving needs a different mind set the sooner you get on ccr the easier it is. you wiil have less preconcieved ideas plus you will not be in such a hurry to extend your depths if are not taking a step back from what you had been diving on OC. If deeper diving is where you want go use the right tools for the job CCR.
