O2 Tank Losing O2 when stored/swapped - bug or feature?

[Walter White Belt]

Sometimes when I start a new game, one of my solutions to deep-dive limitations is to bring more than one o2 tank with me, then swap it out when it gets critically low. However, with BZ I've noticed that when I switch to a full tank, it almost immediately drops to 30 seconds reserve. I dove with 4 full tanks the other day, and when I swapped when the one I was wearing got low, the new one was low within 1 second, as was the next and the last one.

Do any of you remember such a thing with Subnautica 1? If not, does anyone know if this bizarre event is intentional or a bug?

It sounds like this has something to do with the amount of oxygen in your l u n g s vs the amount of oxygen in the tanks themselves, as when you're past 30 seconds you're basically already on an empty tank with the air in your lungs being what's left.

I'll try this out though and see what I can surmise.

I didn't seem to notice this happening to me.

When you're diving, hover your cursor over the Paperdoll UI of your equpiped Oxygen tank. It'll show you how many seconds left of air is in the tank as well as a meter that goes from green to yellow to red.

You can hover over your other O2 Tanks to see how many seconds of air are left in them. Robin seems to be only able to hold 45 seconds worth of air in her lungs, which is a shame.

Agreed on Robin's capacity. Also, I do understand how the tanks work, but I nonetheless appreciate the guidance.

I've been very deliberate in carrying extra tanks and making sure they're all full when I hit the water. Logically, it should be the case that only the tank I'm wearing depletes, since it's the only one I'm using at any given time. But when I doff an empty one and don a full one, I find that it's nearly depleted also. This doesn't make sense, unless it's a bug of some kind, or it's an intentional deterrent to doing exactly what I'm attempting.

I don't see the issue here.

Robin has her lungs with 45 seconds of o², a normal tank is only 30 seconds.

If you swap at 0 you just have your 30 seconds from the tank, Robin's lungs are still at 0, so 30 seconds total.

Tanks when initially created are empty. They only fill when they are worn at the surface or in a sub or base with air. To carry a spare tank of air make sure to equip the spare and watch the O2 meter fill up before diving.

I see now dragonbornzyra actually clarified this earlier; I simply failed to understand it on the first reading. I agree now that it's not actually a problem, but rather, exactly as Ignis succinctly described - Robin's 45 seconds + whatever the tank's capacity = total amount.

Thanks for clarifying. My misunderstanding.

No problem! Have you tried using an Air Bladder? It makes coming out of places like the Koppa Mining site and other caves safe, easy, AND fun! A full Air Bladder will you propel you about 100 meters upward very fast.

I have not, but I definitely will. Thanks!
