"Keep it simple!"
Was the leading mission statement while engineering the 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 ready to dive, backmount stripped or as a sidemount rebreather.

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.
The assembly and disassembly of the SF2 is very simple as the entire tube can be removed and all the internal parts easily reached.
The electronic chamber is located within the head. The adapters of the breathing hoses are mounted at a slight angle on the head. This leads to a perfect positioning of the unit, as well as being, incredibly comfortable.
The scrubber canister is located between the head and midsection. Concerning the midsection, two different requirements of modern rebreathers are combined. First, you can find the bypass (ADV) which provides gas in case of low volume in the system. Second, the adapters of the “Manual Add” are located here.
The electronic chamber is the heart of the SF2. The O2 sensors as well as the Oxygen solenoid and the battery compartment are located here. The O2 sensors are located in a separate chamber to protect them from moisture. The electronic plate is located below the battery compartment. High-quality SMB angle plugs connect the plate with the sensors.
Unique Positioning of Counter Lung
Compared to other rebreathers, the SF2 differs in the unique positioning of the counter lung. Often, the counter lung is positioned on the chest. In contrast, the SF2's counter lung is located in the lower tube. This leads to an ideal diver's position in the water and low resistance.
Manual Adds & Off Board Gas Connector
The “Manual Adds” enable you to add both oxygen and diluent manually. The “Off Board Gas Connector” allows you to add external gas. Hence, the fundamental idea of redundancy while diving is completely secured. Construction-conditioned the entire periphery works while applying “Off Board Gas”.
Convert the SF2 between configurations
The SF2 ECCR is certainly the most popular Sidemount rebreather in the world. Its compact size, combined with a low weight and a robust structure make the SF2 Sidemount a popular and reliable companion on exploration dives around the globe.
The basic components are taken from the SF2 Backmount version. The SF2 Sidemount has the same compact electronics chamber and inner bellows counterlung. The upper and lower tube are constructed of a very light, yet durable carbon fiber.
The SF2 Sidemount rebreather has a new middle part with a manual O2 and Diluent button. Also, the buttons are protected for external damage.
Side Mount Mouthpiece
The SF2 Sidemount rebreather has a DSV mouthpiece especially designed for the sidemount application. In collaboration with the best Sidemount divers in the world, we have developed a unique mouthpiece with excellent features:
- Optimum hose feed
- Extreme small design
- Bayonet hose fittings mouthpiece
- RotatableRight / left hand use
- In water neutrally buoyant
To configure the SF2 Sidemount rebreather as close as possible to the body, it has three attachment points.We’ve designed a stainless steel rail at the top of the head and included two large Boltsnaps in the central region held via a hose clamp to allow for a streamlined attachment to your existing harness. The Boltsnaps can be varied in position, so that the rebreather can be positioned individually.
