Closed Circuit Rebreather (CCR) diving offers a unique and advanced approach to underwater exploration. CCR systems recycle exhaled gas, removing carbon dioxide and replenishing oxygen, allowing for longer and more efficient dives. The choice between air diluent and mixed gas (trimix, heliair, or heliox) in CCR diving depends on the dive's depth and purpose. Air diluent is generally used for shallower dives, while mixed gas is preferred for deeper, technical dives due to its ability to reduce narcosis and oxygen toxicity risks. Scott offers a sequential series of CCR diving courses across UK.
The courses are designed to progress divers through various levels of CCR diving proficiency:
Courses are conducted at various dive sites across UK, offering diverse underwater environments suitable for all levels of CCR training.
These courses provide a structured pathway for divers to master CCR diving, from basic sport level to advanced technical diving. Each course builds upon the skills and knowledge from the previous one, ensuring a comprehensive and safe learning experience. For more information or to book a course, divers should directly contact the course provider.
Air diluent in CCR diving is typically used for shallower dives and involves a mixture of normal breathing air. In contrast, mixed gas (such as trimix, heliair, or heliox) is used for deeper dives. It reduces narcosis and oxygen toxicity risks, making it suitable for technical dives beyond recreational dive limits.
No, these courses are designed to be sequential for safety and skill progression. You need to start with the PSAI Sport Rebreather Diver course, especially if you have no prior experience with CCR diving, and then progress through the advanced levels.
It is recommended that you have your own equipment for technical diving, however, we can hire out the equipment needed at an extra cost.
