If your buddy drops below your MOD (passive panic, buoyancy problems, etc.) then you won't be able to assist them unless you are willing to take a risk on getting OxTox (and if you take this risk and fit then there would be two of you needing assistance/dead).

Any chance you could let me know which section this is in as I can't find it.

Cheers

But this is the case regardless of what your buddy is breathing. &nbsp;If you want to chase your buddy below your MOD then that is your choice, take a breathe, chase and retrieve them and then get the hell out of there. &nbsp;The fact that you are on different gasses doesn't seem to be particularly relevant.

bsac/nitrox thing

Thanks for the link Matt. &nbsp;That clarifies things. &nbsp;The long and short of it is that Andy is plain wrong.

Its the amount of O2 mix which sets yout MOD, not the bottom depth &nbsp;

Its quite possible that your mix is too rich to assist your buddy although its unlikely that you would be daft enough to choose so different a mix. I get the impression that BSAC are just trying to cover themselves here as Nitrox is a pretty broad term and covers any gas between (22% O2 and 99% O2).

Nick,

I assume (based on Fi's comments) that she uses the best mix for the dive based on the bottom depth so there would be no chance of going beyond your MOD - unless you take a showvel. This is what I would do - the best mix that is, not the shovel.

[MATTBIN]

Dont shovels come with Inspirations now? &nbsp;

I assume you mean Andy of the Bsac forum not WL from here?
