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. Rebreathers just aren't safe and although a bail out bottle is carried 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???

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
