Hi guys I was thinking that one day the players might dive 1000 +meters and a 100 sec air tank will not work at all so check this out

EDIT: In fact, I'd say I just like the idea of having more of the gadgets upgrade-able in general. Being able to keep upgrading your items is essential to a feeling of progression.
A single 'standard' steel air (pure oxygen is toxic at depths greater than 30 feet) tank has an approximate capacity of 72 cubic feet of air, pressurized to 2,250 p.s.i. This equates to a Real World dive-time of around 30 minutes at a depth of 30 feet. Theoretically, a diver could safely descend to 120 feet and spend about 10 minutes at that level. This is factored on an average breathing rate, no physical exertion or fatigue taken into account. As a guideline, 'The Rule of Thirds' applies. One-third of the tank's contents are reserved for descent and ascent, one-third for bottom time, and a one-third reserve kept in case of difficulties.
Subnautica's diving rigs are far less forgiving. There should have been significant advances in diving technology by the time 'Aurora' left Earth.
An 'Advanced Diving System' is well-worth including in the Fabricator menu. I agree entirely with Tarek's proposed design and recharging station concept.
Breathing gases can be stored in cryogenic (super-cold liquid) form quite easily, and an ADS would be able to hold sufficient quantities of Oxygen, Nitrogen and Helium (or other suitable inert gases) to provide a bottom-time well in excess of one hour at 1,000 feet. Naturally, significantly deeper dives will incur a time penalty, and possibly include factors such as needing decompression stages on ascent to avoid 'the bends', nitrogen narcosis effects or even HPNS at depths exceeding 2,000 feet.
For the sake of returning some realism to Subnautica's diving mechanics, I sincerely hope the Devs are watching this particular thread closely. I know that the First Aid Kit has already been implemented (Found out the hard way, and had to craft some in a hurry), and it would be a shame to conveniently 'forget' the actual physics involved in deep diving purely to get the gameplay design process wrapped up and call the project 'finished'.
I would think having a good 15-20 minutes of air maximum after equipping enough advanced air tanks is enough and would allow you to do some extensive cave exploring where the Seamoth can't go or you're trying to quietly pass by some large sea monsters.
When you are out of the vehicles by yourself is when you feel the most vulnerable but it's also the most enjoyable when exploring so I definitely think it's a good idea to extend the amount of time your air lasts for in game.
Off course they could always just tweak the current tank values but adding additional levels of more advanced tanks adds to the content diversity & progression which keeps it interesting & gives you goals / objectives to work towards.

all in all I'm in for more efficient air tanks
You can already do that with the oxygen pipes, just run a big length down and into the caverns. You can also top up on oxygen at any of the elbow joints.

Of course we have no need to go down there but still, our seamoth provide that so kinda destroyed that idea thereXD...
There are also two different fins.. one for speed, and one that supposedly recharges hand items.
You can refill these tanks just by surfacing, something that you can't normally do. So maybe they are some kind of special tanks, that allow you to refill easily, but aren't as long lasting as normal ones. That would explain the low amount of air.
Although there are those who can dive deeper but this also involves a totally different air mixture, completely different gear, considerably more experience and a good understanding of the effects of pressure sickness and nitrogen narcosis.
The number 1 rule for any diver in case they get disorientated: Bubbles will always rise to the surface, so up is the direction your bubbles are going.
I have dived before, both with snorkel and scuba and it is surprising how fast you can move underwater, even without fins. You don't swim any faster in this game than an experienced swimmer would in real life. Also, check your feet when you're out of the water, even without the fins on, you still have small side fins on your feet that would aid your speed.
Maybe a slot on the avatar for a tank and doesn't allow a second tank in inventary, limit players to limited air until they have the tech to make bigger tanks allowing for longer time underwater. Each iteration of tank should also slow the swim speed down, forcing the player to make watergliders and powered units to assist with speed.
Advanced tanks should absorb oxygen etc from the water, like fish do.. or use the liquid system that current advanced systems do, oxygen rich fluid that you breatth into your lungs for deep sea diving.
Have been seeing this one quite a lot in the forums.
By the way i think it would be nice if the seamoth also had limited oxygen supply. Maybe you could install additional tanks or upgrade her or build better versions.
This is accomplished using electrolysis which creates breathable oxygen from sea water.
