Unlike traditional open-circuit systems, which release exhaled gases into the water, ECCRs recycle the diver's exhaled breath by removing carbon dioxide and adding oxygen. This sophisticated technology allows divers to maintain optimal gas mixtures at various depths, significantly extending underwater time and reducing the amount of gas needed. ECCRs have become essential in technical, recreational, and military diving, offering enhanced efficiency and safety. Their development marks a significant milestone in underwater exploration, providing divers with unprecedented capabilities.
