18m dives around north or west Ireland

No way. Just remember to breathe out. Done that from 30m +, as a no brainer.

surviving idiocies is not what is at stake here.
Doing simple skills is.

Where have the days of fortitious english longbow tradition gone?
Have you ever spent a second in your diving education... thinking?

Indeed.
It should be practiced from at the very surface, and should imply that
you were able to descend, let's say to a depth of 10m without SCUBa
unit, just mask, snorkel, fins.

The original comment about a CESA from 12m was totally tongue in cheek and
aimed as a gag.

The whole point of a CESA or whatever any other agency want to call it is a
method for OOA divers to ascend to the surface without bursting a lung. This
is achieved by maintaining an open airway to the lungs in "PADI-speak"
making the AAAAHHHH sound. I doubt that a 50% increase in volume of gas held
in the lungs would be survivable. But a CESA from depth is possible if the
constant exhalation happens. I know of people that claim to have done a CESA
from 30m. It is a useful skill it is dangerous if incorrectly performed, but
so is drowning when you are OOA.

Sorry if I sound touchy about this thread, but the OP was new to the group
and asked a valid question and has been flamed so much that he has left.
Considering that this once high quality NG is in a membership decline was it
a good course of action?

This thread is also way off topic now.

What, I thought making that one dive to 20m on the PADI-AOW course meant
you were then qualified to dive to 30m. Surely this is so, PADI wouldn't
lie to me would they?

That's right. You were introduced to the problems of
deeper diving and given an excursion into that range
so you have the basic information to go and do it.

Below 30m narcosis become more evident (not to you)
and gas management becomes more significant but the
step from OW to AOW (18m to 30m) is not that
significant.

There isn't a huge difference between the two grades.
If there were the AOW course would be examined with
things you have to do rather than what are basically
'experience' dives.

30m isn't deep. Stand next to an eight or ten story
block of flats and look up and say to yourself.
"I've run out of air. I have to swim that far to be
able to breath again.". Easy.

You are qualified when you are qualified.
Would you rely on Padi to qualify you?
I would rely on nature, or Darwin.

Club structure in Ireland is CMAS training. 3 training dives, 5 10m
dives, 5 15m dives, 4 20m dives 4 25m dives and 3 30m dives to obtain
CMAS ** diver. 15-20 hours of lectures, pool test before 10m dives
staert. Diver ** test includes diver tow on surface and 200m fin in
full kit. Navigation, tide and dive tables, rule of twelfths etc are
learned. Anyone who says 30-18m is a 12m dive is a fool of the highest
calibre. In fact CFT were largely responsible for the CMAS diver **
training program.
Most senior PADI instructors here are also CMAS Mon **.Hope this
clarifies any view of Irish divers.

You've a lot to learn about internet newsgroups and messageboards.
When you ask for information from strangers for nothing, you should be
grateful for anything you get. Some of the responses will be useful to
you and some won't. Given that any effort anyone expends responding to
your request is an act of altruism, you forego (to some extent) the
right to get indignant about the quality of the answers. You've paid
nothing for the answers and (I may be mistaken here - I'm mostly a
lurker myself) but I don't think you've contributed anything to the
group; so getting shirty about the quality of answers is unreasonable.

For what it's worth - I'd also recommend Scuba Dive West in Connemara
for the quality of the diving and the beauty of the surrounding
landscape. However you should know (I'm assuming your friend is PADI
OW) that most dive centres require that divers have at least PADI AOW
to go on the boats to the more interesting sites even if it's possible
to dive them without going deeper that 18m.

anal smart-ass replies to simple requests is something I'd expect from a
geekier forum, not a sports diving forum where, I'd assumed, the people
would actually partake in more relaxed, less-pedantic discussions

Evidently, I've been proven wrong :)

Personally, I'm perfectly happy that people who indulge in swimming around
in unlimited amounts of stuff you can't breathe, equipped with a limited
amount of stuff you can, are at least a little pedantic.

Just my 0.02 euros.

Deep.

Hi all
Dont know if its any help or if your man has since left the group but
Manorhamilton sub aqua and Sligo sub aqua dive most sundays in
Mullaghmore or north west diving adventures, Declan is a PADI guy will
take you out to thumb rock or if the weathers good maybe to St johns
point depths vary but if you want 18 or less just ask for it the best
dive i had was at st johns in 10 m on the beach side
Regards Feargus
