Anyone have a complete BSAC or other FFM course notes?

Also any practical instruction for diving with AGA masks,
especially Divator Mk II.

When you have to flush it, like when donning in the water,
exhale and be ready to block your airways... The flsuhing
force is a bit violent, and may press water into your lungs
if you are not prepared.
Otherwise, it is a fine mask.
You can switchfrom OP action to normal action easily, by a
turn of the diaprhagm cover.

Huh, I was told to do so ;-), never dissassembled it.
It may be so, as you imply, that this puts some preload to
the diaphragm.
Otherwise, when you doff it, it will not freeflow, jaust
like the Draeger FFM.
