That confuses our code a bit and it thinks that the second pod is connected to a dive with undefined gas data - and then it defaults to air for that</div><div class=""><br /></div><div class="">Do you actually have more than one pod attached? Are you using both? How does this look in the on-watch settings?</div></blockquote><div id="x6d581ebe76d6478" style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">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.</div><div id="x6d581ebe76d6478" style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;"><br /></div><div id="x6d581ebe76d6478" style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">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).</div><div id="x6d581ebe76d6478" style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;"><br /></div><div id="x6d581ebe76d6478" style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">Next single gas dive I do, I could add a backup gas and see if it assigns the backup gas to my second transmitter?</div><div id="x6d581ebe76d6478" style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;"><br /></div><div id="x6d581ebe76d6478" style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">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.</div><div id="x6d581ebe76d6478" style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;"><br /></div><div id="x6d581ebe76d6478" style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">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?</div><div id="x6d581ebe76d6478" style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;"><br /></div>Mark.</div><div id="x6d581ebe76d6478" style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;"><br /></div>
