Balazs,
Welcome to Rebreather World!

We are always happy to recruit new members to the "Dark Side" of diving. Now that you are "infected", it is too late. You can never go back!
Read our articles. Talk to the folks. We have a large and active SCR group as part of our community, and they will give you a lot of help.
Again, welcome aboard!
