Multiple tank dive bug

[henrik]

Scenario: Twinset on my back, stage bottle under my arm.

I start breathing from the twinset, switch to the stage bottle early in the dive, and switch back to the back gas late in the dive.

MacDive now shows that I have a twinset, a stage bottle, and another twinset. This works like it should in Subsurface (only one twinset), so I guess there's nothing wrong with my HelO2.

This is working as expected.

You are not looking at the individual tanks you used, you are looking at the tank/mix you were using at that time. So the second twinset is correct - it's what you swapped to.

It is the same information, just displayed in a different way. Think of it like:

1. Breathing off twinset.
2. Breathing off stage.
3. Breathing off twinset.

Look under the profile, in the Gases tab. You will see the gas you were breathing at each time. It's a visual representation of the same thing. Does that help it make more sense?

OK. But under "Gas Management" it says "Tanks used on this dive", and I see two twinsets. Since I did not use a second twinset, this didn't make sense to me. But I see that it simplifies start/end bar for each tank switch.
