ScubaForce 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 fiber 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.

Streamlined Design

As if it were designed from one piece, the SF2 is shaped cleanly and simply. Moreover, the carbon fiber tube gives the SF2 a new, streamlined and high-quality design.

Easily Built

The assembly and disassembly of the SF2 is very simple as the entire tube can be removed and all the internal parts easily reached.

Compact Installation

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.

Electronic Chamber

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.

KISS Sidewinder

The KISS Sidewinder rebreather has taken on the industry by storm, and has proven to be the most popular sidemount rebreather ever. ​

The Sidewinder's innovative split canister design allows for the smallest profile while maintaining perfect hydrostatic work of breathing while diving. 

Sidemount rebreathers have historically taken on the form factor of a sidemount open circuit tank. While this design attempts to mimic the streamlining of a sidemount cylinder, often hydrostatic work of breathing issues result if the unit isn't perfectly rigged and mounted. Even when it is, the work of breathing is only optimal when in certain diving positions. 

The KISS Sidewinder rebreather solves these issues by splitting the canisters on the diver's left and right sides. These are connected by one 8-liter counterlung, which spans across the diver's back. The result is a super clean, streamlined configuration which provides excellent work of breathing in most diving orientations.
