Or how do you interpret the specific restrictions or limitations for it?

They're all listed under the same description. It's the GMs call. Anything for swimming at any depth isn't just air, it's compressed air.

Yes, I agree, that is how I saw it too. However, my brother got the strongholds of resistance book and told me about the organic gill, so I started wondering..

I'd say that the cheapy ones are just for filtering your air. Some of the nicer ones can allow breathing under water to limited depths. If you want to go super deep you need the Gill, a dive suit, or some sort of compressed air.

Agreed. A standard breath mask is really just a filter, while one of the ones from Empire might be usable only for something like snorkeling.

Breathers, like sensors, need to be designated to certain use.

I figure you have to specify which one you want to use. The breathers Han and Leia used on the asteroid in ESB, for example, were probably not designed for underwater use.

The ones Han and Leia used struck me as something you use in an Oxygen deprived atmo, where there is still atmo pressure that's suitable and sufficient temperature, it's just there is a lack of O2 and the masks are proving it supplementally to what is already there for gases.

Diving is a very complicated sport in RL and without very simplyfied physics playing an adventure containing dives would be no fun for the players. So as a GM i would create a custom device for diving with the systems needed to supply the PCs with air and a small and simple droid brain to care for the technical aspects of diving and a suit to keep the PCs warm and save. In game it would be a 250-500 Credits device that works like an upgraded breath mask for underwater use and the basic version is usable down to about 50 meters. The availability would be about 1 on holiday-worlds with underwater facilities and up to 4 in the rest of the galaxy as such devices are rather uncommon. I would not recommend the use of standard breath masks for dives that are longer as about 10-15 minutes and deeper than 5-10 meters and there would be some red dices to reflect the dangers of such unsuitable gear.

Or you could just use the enviro-suit.

Of course a mechanic may try to take a simple breath mask designed for filtering O2 out of a toxic atmosphere and adapt it for underwater use... with a suitable difficulty.

A basic, cheap Space Suit could also get the job done. Armors may also be modded to be Vac Sealed which would include water sealed. The only issue would be extreme pressure at very low depths. I would probably say a cheap Space Suit couldn't handle the extreme pressures but if you had Vac Sealed your Laminate or Heavy Armor it would suffice.

I wonder... not assert or suggest, mind you, just wonder... if this is one of those situation where "Star Wars" science and actual science don't quite match.

That's pretty much all science between the two, although up still appears to be up and down is down in Star Wars....

As I mentioned, I'd use the Enviro-suit for really complex dives, a cheap basic breath mask/respirator as something like a snorkel, a more expensive respirator for something like SCUBA gear, and the organic gill (SoR) and Aquata rebreather (KtP) for something in between. And the AoR Beta has the stats for the Seatroopers, who have diving suits , if you want to customize something.

its my understanding that those are more like gills then anything. There expensive, but you can buy devices that are very similar looking to those, albeit a lot bulker at the moment. In the mouth piece is a type of valve that switches bases on if your inhaling or exhaling. While inhaling it draws water in from one side, and acts just like a gill, letting the newly separated hydrogen free, while you breathe in O2. then when you exhale, the CO2 exits through the other side, which is also where the hydrogen exited as well.

There is no up or down in space and no hard science in space opera.

Alastair Reynolds would disagree with you.

But I agree with your basic point. Don't worry so much about the science aspect, but don't dismiss scientific issues outright. Come up with a quick way to address the issue and then move on.

There is no up or down in space and no hard science in space opera. Fictional worlds Follow their own rules and make up their own laws of physics and ignore the ones that doesn't fot the genre or vision.

Apparently there's no sense of humor in space either....
