    Breathing oxygen through scuba regulator

    It's a bit unclear, but I think you are asking how to fit a scuba regulator to an oxygen tank. You have seen that they don't fit together! The oxygen tank has what is called a "Pin-Index" fitting and the scuba tank has a DIN fitting. I'm assuming you have access to oxygen tanks from your local...

    Carbon Fibre Tanks And Weighing

    I am thinking about buying some Carbon Fibre (CF) tanks. Partly because they are much lighter than Steel or Ally's and I sometimes want to drag tanks through dry cave to get to sumps.

    Newbie confused about Side Mount

    I am also just getting into sidemount now, after several decades diving. What I am learning is that it takes a lot of fiddling around to get the rig right. It isn't yet. You will have to buy some new gear. It feels very different to back mount diving. I agree that unless you have a good...
