can i use it with twin tanks?
It's set-up for single tank. Don't know if there's a way to reconfigure. Sorry I can't really help. Never considered using it for duals.
I've used mine with an 80 cu. ft tank and a bailout tank with sideblock reg, but not two full-sized tanks.
No - the back plate on this BC is setup for a single tank. If you want to dive with two tanks you are probably better off looking at a plate and a wing and not a jacket style BCD
No , I don't think so.
No, it's a single tank setup. Only one strap and a backplate with the bladder wrapping the side of the tank.
No, there is a back plate that is specific for only one tank. I am not sure if there are modification's you can do to it, but as it comes from the factory, No.
Unfortunately no, this BCD only accepts single tanks.
No, but if you find a way to do it, the lift is not enough to support twins
