## Short summary

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. Course Sequence and Overview The courses are designed to progress divers through various levels of CCR diving proficiency: 1.

### Highlights
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. Course Sequence and Overview The courses are designed to progress divers through various levels of CCR diving proficiency: 1. PSAI Sport Rebreather Diver: Utilizes 100% oxygen in Closed Circuit Rebreathers. Training depth limited to a maximum of 30 meters. Focused on sport diving activities without decompression. 2. PSAI Advanced Rebreather Diver (Decompression Diving): Suitable for divers using Closed Circuit Rebreathers with air diluent for decompression diving. Depth qualification up to 40 meters, with correct decompression skills. Prerequisites: divers must have completed the Accelerated Decompression Procedures course 3. PSAI Fundamentals Closed Circuit Rebreather Diver (60 Meters): Designed for divers using Closed Circuit Rebreathers with trimix diluent. Extends diving capabilities to 60 meters. Focuses on the fundamental skills for mixed gas diving. 4. PSAI Explorer Closed Circuit Rebreather Diver (100 Meters): For divers advancing to Closed Circuit Rebreathers with trimix, heliair, or heliox diluent. Maximum depth of 100 meters.

## FAQs

### What are the differences between air diluent and mixed gas in CCR diving?

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.

### Can I enroll directly in the Advanced CCR courses without prior CCR experience?

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.

### Do I need my own equipment?

It is recommended that you have your own equipment for technical diving, however, we can hire out the equipment needed at an extra cost.
