CCR (Closed Circuit Rebreather) diving

Closed Circuit Rebreather (CCR) diving involves a specialized scuba system that recycles the diver’s exhaled air by removing carbon dioxide and adding oxygen, allowing for extended dives with minimal gas consumption. Unlike traditional open-circuit systems that release exhaled bubbles into the water, CCRs are virtually silent and produce no bubbles, enabling discreet operations. The diver monitors and adjusts oxygen levels throughout the dive, requiring proper training and maintenance. CCRs are preferred for technical, deep, or prolonged dives, offering greater efficiency, reduced gas costs, and a more streamlined profile. However, they demand careful management and understanding of the equipment’s functions for safety.
