Oops sorry, late reply.
It was translated from finnish.
I did a few introductory dives but I'm not a diver myself. Although I have an interest in rebreathers and in technical, saturation and cave diving, so I've read quite a lot about it and I have collected some theoretical knowledge. Not unlike the little bit of aeronautical knowledge we develop while playing flight sims.
Could you point me to the wrong terminology used? Thanks
