Keep it simple!
War das Leitmotto bei der Entwicklung des SF2.

The vision became mission and finally reality. This is evident at first sight: The SF2 is configured very cleanly and simply. Compared to other rebreathers, the SF2 is compact and well-arranged. The reason: All important components are integrated into the carbon fibre tube. Therefore, the SF2 needs significantly less volume compared to other rebreathers. Tests, as well as various certifications, assure a constant level of security while diving. The SF2 is especially suitable for ambitious technical dives. It is available as either a backmount or sidemount rebreather.
