Garmin Mk2i - unlikely dive gas

Hi Dirk,

I was thinking about this in bed after I sent you my FIT last night, but
didn't have the brain power to work through it, or the desire to start
wading through the Garmin menus. Yes, I do have two transmitters
connected and for all these dives only one gas mix.
The first transmitter is mine, and is set to be included in SAC
calculations. The second transmitter is on my partner's regs - she's
only just started diving, and I like to be able to keep an eye on her
pressure at a glance. The second transmitter is excluded from SAC calcs.
I've had a look through the dive setup on the watch, but it doesn't look
like you assign a gas mix to a transmitter, even in multi-gas mode. I've
not done multi-gas dives with my Garmin, so I don't know how it deals
with matching mixes to cylinders (or indeed if it does).
Next single gas dive I do, I could add a backup gas and see if it
assigns the backup gas to my second transmitter?
It'll probably be a while before I get out again, but I can experiment a
bit over the next few dives if you think that will help.
When I first import these dives with two transmitters, the graph shows
both cylinder pressures, but the SAC rate is blank until I delete the
second cylinder. I assume something in there is also confusing
Subsurface's SAC calcs?
Mark.
