    G'day folks,
    I have recently started diving twins and I have a back condition. Because of this, I am looking at getting 2 12l carbon fibre tanks to save myself lifting a few extra Kg's

    Do any of the Aussie scuba divers here dive with carbon fibre tanks? Are they certified for use in Australia?

    Cheers blokes

    What you save on the tanks, will end up landing on your weightbelt. Heavy tanks hurt a lot less than a heavy weightbelt.

    Might be a better idea to consider sidemount?

    SCUBA tanks are susceptible to external damage through handling and external damage to a fiber tank may very well be end of life for the tank.

    I agree with @michael-fisch and @scrane. For the reasons they provide, I just don't see CF tanks as a viable option.

    With any damage (scratch) going through the paint on the outside of a carbon fibre tank it is required to condemn the tank. Also carbon fibre tanks can only be hydro'd twice, Once before you buy it, several years later is the 2nd hydro, and the tank has to be condemned before the 3rd hydro.
    It's a good way to keep carbon fibre tanks in relatively new condition since the detonation of an old or damaged carbon fibre tank can cause death, injury, and/or major property damage.

    thanks for the feedback guys. I have been looking at aL vs steel too and it looks like steel is again less than aluminum.

    Steel tanks it is
