CCR rebreathers differences and what to look for

Why Choose eCCR Over mCCR?

Automation and Safety

Modern diving technology has dramatically enhanced diver safety through electronic control systems. eCCR systems automatically maintain optimal breathing mixtures, allowing divers to focus on situational awareness and reducing the chance of human error.

Limitations of Manual Systems

Manual CCRs (mCCR), while offering precise control, require constant attention—especially during ascent when oxygen management becomes critical. In emergency situations, task-overload can easily distract divers, increasing the risk of dangerous hypoxia.

Standard eCCR Systems

Standard eCCRs reduce diver workload by automating oxygen injection based on real-time sensor readings. This allows divers to focus on navigation, buoyancy, and situational awareness. However, many commercially available eCCR models do not offer robust backup systems. In the event of an electronic failure—such as a controller or sensor malfunction—there is often no secondary system to seamlessly take over. This lack of redundancy can place divers at risk, especially during deep or extended dives where bailout options are limited.

Redundancy in Modern eCCRs

Concerns over electronic failures once favored mCCR systems. However, today’s eCCRs, including the Liberty, incorporate robust redundancy, making them highly reliable even in the rare case of individual system component failure.

Hybrid CCRs

Hybrid systems (hCCR) combine manual and electronic components. While they use the same constant flow orifice (jet) as mCCR—thus being depth-limited like mCCR—they have an advantage in that the electronics monitor the oxygen partial pressure. However, unlike eCCR systems, these electronics are usually not redundant.

Intuitive Interface and Long Battery Life

User-friendly interfaces and excellent battery efficiency make the Liberty ideal for long, demanding dives.

Optimal Breathing Comfort

Effortless Breathing in All Positions

The Liberty ensures consistently effortless breathing in all diving positions, improving comfort, reducing fatigue, and enhancing diver performance.

Common Buyer Mistakes to Avoid

Prioritizing Cost Over Value

Opting for a lower-cost system might seem like a smart move upfront, but in the long term, it can compromise safety and performance. Cheaper systems often cut corners—whether it's through limited sensor redundancy, lack of reliable electronics, or offering only manual (mCCR) operation. As covered earlier, mCCR systems demand high attention and carry increased risks in high-stress environments.

Choosing a reliable, well-supported eCCR like the Liberty helps ensure you're investing in a system that can grow with you and perform consistently in all conditions.

Overlooking Serviceability

Selecting an eCCR without accessible local service options can become costly and inconvenient.
