CCR training question

[davehicks]

I think its a touch dodgy !!! ... it seems less of an issue to me if its an existing CCR trained diver doing a X over to a second unit. However thinking about my first CCR course, there were things mentioned in the course, the nuance of which, I didn't fully comprehend, perhaps for 6 months afterwards.

And yes I have had a buddy pass away on a FMCL incident

What exactly is a FMCL incident? Why is the type of counter lung responsible for an accident, and not how the diver used it or responded to a failure mode?

That's why I was suggesting talking with the instructor. They might have enough to teach both ways. Or a crossover class. Options exist, but you have to talk with the instructor ahead of time to see what they feel is appropriate.

Could the instructor have a set of FMCL you can borrow?

Whilst I don't think FMCL are inherently more dangerous then BMCL units, they provide a lot of flexibility with regards to configuration.

For example Bailout could be sidemounted, backmount doubles, backmount single, O2 can be offboarded or onboarded, butt mounted or clipped off to a d ring. This means that the manual adds and hose routing can be very different dependant on the diver config. Having an instructor set up a configuration is useful.

Comfortable bail out scenarios can be impeded by chest clutter and hose routing choices and developing the muscle memory for new configs is not always straightforward.

Unfortunately no, the instructor doesn't dive FMCL himself and from what I'm hearing second hand he doesn't really believe in them.

Many thanks for all of the input on here.

After a fair bit of discussion the student has canned the course due to wanting to learn on the configuration that she is going to be diving going forward, and the instructor not being overly knowledgeable about FMCL.
