Its fairly sound theory - the recirculating water is at the surface, the
flow through is in the deeper water ..... And that's what you need to
dive
into to get out of the stopper. I'd try diving with my BA on first
'though cos if the flow is as strong as a stopper you (almost) can't get
out
of implies you'll need you BA once you do get out of it. But I guess if
you
were going to drown if you didn't.....

The last "official" recommendation that the BCU safety people put out I seem
to recall was NOT to do this, but as you say, if it is really your last
resort then what have you got to loose.

On the other hand, if you are still strong enough to take off your BA (no
easy matter), would it be better to wait for help to arrive - presumably
help can't be too far away unless you have been pretty daft.
