Dear Barry,
Anything that most of us have access to. Rebreathers are far from =
standard
kit for most divers on this list. Even I have a passing interest in them =
,
as most do i'm sure, but when it comes to the nitty gritty its pretty =
damn
boring from a non rebreather owners point of view. Maybe when they are
cheaper and work a little better we'll all be able to get on here and
prattle on about their ins and outs but untill then why dont we just try =
and
get simple things like hogarth, independent v manifold and what a stroke =
is
worked out first before you guys go confusing us with all this =
rebreather
black magic shit.
Thanks,
Scott
