TDI Deco Gas Reserve

[Chris Thomas]

Are you suggesting something like Helitrox on Mod 1?

Yeah, makes sense.

Given a choice, most people would dive trimix on dives deeper than 30m but the cost is prohibitive. The gas usage on CCR makes the cost of a trimix fill almost too cheap not to dive trimix beyond 30m.

OK, you have convinced me. It will be in the next issue of the TDI standards.

I think this would be a very forward thinking and reasonable stance from TDI UK. Having experienced quite a bit of warm water diving this year, I can see why it is air dil in those places (He is sometimes difficult to source and blend) but a choice of 21/35 over air dil for any depth on a rebreather for a UK or other cold water diver would be obvious. This is particularly true if they are already OC Trimix/helitrox trained.

fook me you guys want it all ,

you post about guys taking mod 1 that are not up to the mark , diving with air then you say, hay ill sort them out with some He and a mod1 course , brill


if a diver has a breather and is only using air in said unit , then he needs a course for being a half wit . not a course about Helitrox what ever the fook that is lol


just to let some of you know , you can put what ever you like gas wise in your unit no one will mind ,

at the risk of opening a can of worms i have a question. actually it's more like a request for advice really.

currently BSAC DL/OWI, with ADP, and want to move onto trimix to allow progression onto some deeper stuff i.e 40-50m. not interested in going any deeper than that. i'm after a course that will teach this but also certify me for primary donate so i can fulfill my duty of care with BSAC. have been taught it but no formal certification. don't want to start a debate about the hog looping thing all over again, it is what it is, just after peoples opinions on TDI, IANTD etc. and which course might be best suit my needs.

opinions?

I have a similar background. I did ADP and then did TDI Adv Nx & Deco procedures. I then decided after the TDI course that air diving below 40m sucked. I passed the course OK but did not enjoy the narcosis below 40m.

Subsequently I have done fundies and want to do T1 next. Although it would be two courses rather than one it would satisfy your desire to do trimix and learn primary donate. I believe there to be other benefits too :-)

I totaly agree in principle but some people have wives kids and life insurance policies that wont pay out on divers diving outside their qualification.

I am very lucky my life dosetn work like that but if I were a 9-5er with a life insured mortguage id be a lot more conservitive about such things.

Hallelujah. Been saying this is needed for years (18 months in reality). The right way forward. Furthermore TDI should recognise prior open circuit trimix qualifications when considering mod 1 training needs and certification.

Yep, if you are already Helitrox or Trimix qualifies then you will be able to use that within the limits of the Mod 1 certification. I have a copy of the standarda nd have been testing it out and it will be in the next issue of the standards which will be this quarter.
