How to get Accelerated Deco?

[TerryH]

Tried this on the BSAC forum and just got more confused, so try here
instead.

Have a bunch of BSAC DL/ADV, all BSAC Adv Nitrox/twinsets and living
around the 35-40m mark. Averaging anying from 200 - 1000> UK dives each,
they are asking what next?

This group has been doing the stuff in the ERD syllabus for a few
years now, so there is a reluctance to spend money on that.
Trouble is what we really need is to be able to do acclerated deco.

So bearing in mind this is a student club (no wads of cash) that is nearly
always doing deco diving, what course would give them AD?

Got lots of replies saying Instructors are flexible etc. What I need is specific
info. Your BSAC grades start you on this, give you that, can do this at x
cost etc.

Any ideas?

Otherwise it's TDI/IANTD courses but these will be more expensive than the BSAC ones.

Not going to go into the 100% / 80% debate here, but I think now BSAC SDPs say you can use 100% (although 80% is recommended) but you still have to stick to a 1.4 ppO2. Which isn't much use for the sea. This was changed a few months ago, but not publicised much. I could be wrong though.


Terry,
You asked about specifics. A group (about 8 or 10 of us) are doing ERD / Trimix with Jack Ingle. I *think* costs are around £250 for the 3 day ERD course and £350 for the 4 day normoxic Trimix course but I don't have the details in front of me. Accomodation is extra. It might be worth calling him and seeing if he'll put together something that fits your group.

The course is in May, so I can't comment on what it's like, but I'm looking forward to it.

Laters,
Janos

EDIT: For the trip we're doing, the entry requirement was BSAC Advanced Nitrox (for either ERD or Trimix).

Don't BSAC have a PO2 limit of 1.4 even during deco? If so you can rule out accelarated deco within branch dives.

The next safe and logical step for your guys is normoxic trimix with a proper tech agency (and a DIR-F course to fine tune their skills

Regards,

Mark.

I'd suggest going with a Technical agency TDI/IANTD/ANDI or even GUE, yes this might cost more than you are used to paying for BSAC but then I don't believe you can do Technical diving on the cheap.

John,

I think that's the BSAC website being slow to update again. Have look at
this post from Mark Rowley on the BSAC Fora:

Janos,

This is all well and good but BSAC is not a Technical diving agency, or club whatever, why not go where the experience is rather than waiting for some fudge around existing club rules? I can understand people being loyal to BSAC but when it has shown itself to be too slow to respond to an obvious need why can't people move on to more suitable agencies?

Hi Ian,
Definitely. Although you'll note that I didn't suggested that Terry does a BSAC course. Although I guess it was implied...

Although I'm a great fan of BSAC at the branch level (certainly my branch ) BSAC nationally are lacking an offering at the more technical end of the spectrum. I would quite like to see BSAC offering trimix and rebreather courses for those that want to do one. BSAC are making steps in this direction and good luck to them say I.

However, Jack is a TDI and IANTD instructor as well, and to be honest, I don't know for certain which agency's qualification I'm doing in May I'm guessing that it will be the BSAC because it will be the cheapest, but obviously the trimix won't be BSAC.

Personally I'm doing the course to improve my skills and technique (as those who've seen me try and dive will tell you - there's a lot of room for improvement) and as so agency differences such the 80% / 100% don't really affect me - I just pointed it out so that people knew you could buy 100% if you wanted to.

Anyway, this is turning into a bit of a hijack - sorry Terry - I pointed it out becuase Terry's based in S London, what we have chosen might work for you. Or it might not.

Laters,
Janos

PS - Bah. Blown out so off to do some more cleaning around the house. Will check on thread a bit later at around the time for my next mug of tea.
