Multideco... tips and tricks?

[ACA]

So, after 3 years of Ralph’s original post, his question was does a user manual exist for MultiDeco other than the help icon of the software? The replies only refer to how each uses it….. No offense but, does a user manual exist for MultiDeco. Thanks in advance.

Not a user manual, but a lot of useful stuff here.

Btw, say hello for me to la belle province.

Thank JMBL.

Does multideco provide the gas volume usage of diluent and o2 when on CCR? I can't find it anywhere and only see OC deco consumption.

No.

O2 usage is approximately constant metabolism, circa 1 litre/min if gentle, double or more if working hard.

Diluent depends upon depth changes and efficient loop management, particularly flushes and turning off the ADV.

Thanks. That makes deep dive planning just a tad more annoying then it already is

Not really. You only use a little bit of oxygen and diluent for each dive. You’ll quickly know what your personal consumption is for your CCR dives. Add a margin and that’s that.

Or just start big dives with full oxygen and diluent cylinders.

The biggest constraint is nearly always the practical amount and types of bailout you can carry, especially for deep or long penetrations.

I did a 2.5 hour dive yesterday, max depth only 54 meters, and took my o2 from 177 bar to 37 bar on an AL13. We've been discussing a 115 meter dive coming up in April and its got me concerned. I certainly can't use the 2L cylinder for that dive which, as it looks will be a 4 hour dive. Looking more like a full AL80 of 100% and a full AL80 of 10/60 would be enough but that recent 2.5 hour dive got me second guessing. I guess I need to re-figure out my o2 and dil consumption. This much o2 just for deco but then ?? (o2) and ?? (dil) for the working part of the dive...

This dive becomes less and less worth it. The bailout costs would be absurd.
