Twinset/ Rebreather question.

Can't remember what the min logged dives is, but you definitely need a Basic Nitrox and Advanced Nitrox cert. With some instructors you can do the Advanced along with the MOD1.
I know some very good Trimix CCR divers who have never even used a twinset, its not a stepping stone, its an option.
I would recommend going CCR sooner rather than later. I didn my MOD1 this year and now think I would have been better off doing it 5 years ago or more, rather than building and using my twinset.

Two words: gas switches....

Breath in ,breath out ,repeat ?
Only difference being the gas lasts longer !

i went CCR at the earliest oppurtunity and haven't looked back at all. I'd done a couple of years diving and the oppurtunity arose. I have the good fortune to know a range of CCR divers who often buddy up with me and help progress my experience, i've no intention of racing to depths but building slowly my experience and knowledge and comfort levels.

better to get in early and learn nice and slowly.

Okay, bit of background. This will all be a few years in the future as i feel i need more experience first but, at the moment I dive singles and I find my dives (depth) are being limited by my gas, not by experience (or lack there of.)

In the future I would like to dive with a rebreather. But my question is this, should I buy a twinset first to experience the depths that are currently inaccesable, or go for it and do a rebreather course and save the money I would spend on another cylinder, valve, regs etc etc.

Would it be strange to go from single to rebreather?

I hope that made sense!
And thanks in advance for any replys.

This is the report from my Mod 1 this year

Mod 1 with Dennis Vessey

You will need Advanced Nitrox, you can do this at the same time.

100 dives is the minimum for the PSAI coarse for the meg. I assume it will be similar for other units.

It is a different mindset, but if you are prepared to be absolutely scrupulous with your unit's preparation, have the patience to do the checklists without fail everytime then go for it, Only you know whether you can do that, there are no shortcuts.

I have received some advice from some very experienced people lately, one of the things that cropped up was "Go somewhere warm and dive the unit all week" Unfortunatley I had booked a holiday to a non RB friendly destination before I did the course . You have to get in the water and dive it, a lot.........I will know have to wait until later in the year.

Whatever you choose, good luck.

Oh and don't be sucked into the "This is the best unit in the world internet bollox" There is no perfect unit. How you choose a unit is very very difficult, there is a lot of marketing bollox, there is a lot of agency bollox and its hard to cut through the crap..........................................:fro wn:

I dive a meg, I cannot recommend it to you for the simple reason I have no idea what the others are like.

If you do go for it with RB, try to find an instructor who Owns a unit and dives it themselves. There are a couple of people on this board who may be able to advise if you ask.

If you do it, don't be afraid to ask questions, the only really stupid question is the one you didn't ask. Expect to take some stick if you do ask a numpty question, but take it as a learning experience

Whatever you decide
Good luck

I went to CCR after 30dives on a single , so I would say go for it. I believe the IANTD standards don't have a minimum number of dives - just the 25 needed for advanced nitrox. Feel free to PM me if you want to ask anything..

Particularly attractive way of mounting your main/only gas source, the pin yourself to the seabed method I believe?

ps I seriously considered going from a single OC gas source to a semi rb to get more bottom time without the weight issues of a twinset, until I realised of course bailout has to be thought about too. Having said that I would go rb if my diving required it, so in short work out what diving you want to do and what kit will do the job, as Chasey says if its >50m then RB is probably the way to go.

Having been through the slow route from single to double to trimix etc etc I would say that if you are going to definitly end up going CCR then do it now.

Talk to a reputable instructor like Al Wright, Phil Short, Gary Fox, Aaron Bruce etc and discuss it with them. I know some instructors have taken on CCR students with 20 dives.

CCR is a different skill set to OC, so if you are definitly going to end up there then you may as well save all the time and effort in between

How do you 'definitely' know you are going to end up there tho? Bit of a chicken and egg argument if you ask me

Well the OP seems to think thats where he is going or I guess he wouldnt have asked the question

I dont see it as any different to the 1001 questions we get on here asking

should I buy a BC or a wing or

Should I buy a semi or a dry suit for UK diving.....

To take ants point though if you are unsure as to whether CCr is for you do a course on an instructors unit and get a feel for it
