CCR Extended Range (rEvo)

1. Course Restrictions and Dive Limits

Upon completion of this course, you will be certified to dive within the following scope.

• Maximum depth: 40 meters (when using “air” as the diluent gas) / 45 meters (when using “trimix” as the diluent gas *Strongly recommended to reduce gas density and enhance safety*)
• Course Decompression Limits: Planned stage decompression (decompression stops) of up to 10 minutes is permitted.
• Equipment: Carry one bailout cylinder to switch to open-circuit mode in an emergency and ensure survival.

2. Features of the “rEvo CCR” Unit

SSI’s CCR course is

“Unit-Specific”

We conduct training focused on the rEvo’s unique structure and its specific operation and troubleshooting methods. The rEvo is a Belgian-made rebreather that offers the following unique benefits:

• Dual Scrubber: The canister that absorbs carbon dioxide (CO2) is divided into two sections. Since the adsorbent inside can be replaced alternately, it allows for safe and efficient operation without waste.
• rEvodream (Monitoring System): It features a proprietary HUD (Head-Up Display) that monitors oxygen partial pressure (PO₂) in real time and includes a backup system.
• Ultra-thin and low-profile: Its sleek, streamlined design fits neatly against the back, making it easy to maintain a streamlined trim position underwater and making it ideal for narrow spaces such as shipwrecks and caves.

3. Main Course Content

During the course, we thoroughly instill the knowledge and skills necessary to safely perform deep dives involving decompression.

• Academic Course (Classroom Instruction): Management of “gas density” associated with deep and extended dives, crisis management for hypoxia and hyperoxia, and decompression theory.
• Pool and Confined Water Practical Training: Assembly and inspection of the unit; repeated troubleshooting exercises simulating potential system errors (such as oxygen sensor failure, solenoid sticking, or water ingress).
• Open Water Practical Training: A practical exercise in performing a safe accelerated decompression ascent while carrying a bailout bottle (stage cylinder) and maintaining perfect control of buoyancy and trim.
