Dear All

Having now signed up for fundies and eventually aiming to go onto tech 1 then GAS is likely to become an even bigger expense. At present I am IANTD Trimix and probably doing 12-15 trimix dives a year- rest on Nitrox mostly in the 25-30m range. I would like to move onto deeper diving but only with like mined people. Having done depper dives with people on air and people on rebreathers then I would be much more comfortable in a team. Whilst the air people were experienced I will not dive to these depth on air. I don't know enough about rebreathers to form an opinion but in order to be safe would require considerable training -hence they are not on my list,I would rather have other divers on a set up identical to mine. I did IANTD trimix with 2 rebreather divers in Dorothea and felt very lonely!!

Whilst I am happy with my training things could be better - hence going DIR.

How do you currently find the gas logistics and costs for a typical weekend. I am assuming standard gases 21/35 and 2 trimix dives over a typical weekend. Diving Weymouth and Plymouth I would of thought was fine but what about locations further afield?

Is it worth having 2 twinsets - one for Nitrox and one for mix so that you can do two dives a day. Must admit that this seems like the best plan, seperate sets for each respective gas- but is this overkill???

Thanks

Hi Ian,

For most of my Mix diving in the UK, I'm normally only doing 1 dive per day, so only need the 1 twinset. However if I know I am doing a weekend somewhere with limited gas logistics, I'll take 2 sets, or a bottom stage and 1 twinset. Depends on the dives really. Tech1 range dives, then 2 sets of twins, and 2 50% bottles is easy.

Currently I own 2 sets of 12s, but I suspect that will go up over the next year, as I pretty much always have mix in at least 1 of those sets, and in the summer tend to have mix in both, so still need a set to use on courses, and shallow dives.

Don't know if that helped at all.

Thanks
John

Thanks John

I think that the two set option is probably the route I would go.

Fiona

personal opinion- I am sure that rebreathers are perfectly safe if you have been trained and dive with like mined people. Having used up my 9 lives I know that they are not for me

Yawn... another diver with no experience passing judgement on something he knows nothing about...

Thanks I have plenty of experience - (diving 22 years) and enough knowledge to know that rebreather's are not a route that I wish to go down. Whilst a rebreather would offer an advantage on logistics and gas costs- it is my preference not to go down that route having spent time discussing this with existing users and with qualified rebreather instructors.
Sometimes it would be nice if instead of making a snap judgement about someones level of experience and interest in a subject that people come back with helpful responses and not the standard "oh they know nothing about this topic or that subject".

And how many on rebreathers? Enough to make such a definitive statement on their safety?

Ian, sorry but you did say "Rebreathers just aren't safe" that is completely different to you not wanting to go down the RB route.

I don't want to go down the RB route but I have no issues with them and the people that use them, I have buddied with RB divers and have never had any issues with it.

Anyway lets move on. I am not trimix qualified although the trimix route is something I would eventually like to move on to, not for deeper dives but continue with my current dives of less than 40-45m but remembering what I saw when I was down there.

I do have two sets of 12's as like you I think it takes the gas issues out of a weekends diving.

Agreed

Lets move on, two sets seems to be the way to go.

Thanks all
