I'm not sure how difficult it would be for the Developers to add different tank setups and tank sizes.
Single AL80 cuft
Steel 100 cuft
And my favorite Steel 133 cuft
Surface Supplied Diving (http://www.seabreathe.com/)
The different sized tanks seem like it would be relatively easy for them to fit in. The surface supply would have to be a nightmare to implement in any way that would look believable though.
Double tanks would be great even a nitrox tank would make me happy.
This would be a great way to teach new scubadivers why and how to plan dives (Nitrox DIves too) and how Nitrox changes the dive profiles. Depth vs. Time. +1 Nitrox Tanks.
A rebreather set up would really be cool, which would go great with a cave or cavern dive map.
Re-breathers with Tec Computers would be Awesome. I would love to see how a tec-rec dive on a rebreather with comp stats would run like at depth.
Surface supplied air would also give a purpose to the lovely old-fashioned copper diving helmet - then all we'd need is the rubberised canvas diving suit and the great big lead boots to go with it. It'd make a great change to go clumping around on the bottom and climbing into wrecks! I think a bit of historical diving would fit very well with the wider concept of 'World of Diving'.
I would like to see a 3 gauge console as an option, that's what I use irl.
Seconded. A three gauge console would be pretty awesome. +1
For cave diving tanks are very often below the diver or on the side:
