CCR TRY DIVE

CCR diving uses a rebreather unit that recycles the diver’s exhaled gas, removing carbon dioxide and replenishing oxygen, allowing for nearly complete usage of breathing gas. Unlike open-circuit scuba where exhaled bubbles are lost to the water, CCRs offer silent operation, optimal gas mixtures at any depth, and minimal bubble emission, which is crucial for research, photography, and approaching marine life.

• Extended dive times and gas efficiency: Nearly all inhaled gas is reused so dives become much longer, even at depth
• Decreased decompression obligations: Divers can optimize inert gas exposure, reducing or even eliminating decompression in some profiles
• Minimal bubbles: This lowers disturbance to marine life and improves stealth for scientific, photography, and cave diving applications
• Warm, moist breathing gas: Improved comfort, especially on long or cold dives
• Significant cost savings on helium and specialty gases: More economical for repeated and deep technical dives

Donarun Das stands out for his leadership in technical diving across Asia, recognized as India’s deepest civilian diver and an international instructor for CCR (Closed Circuit Rebreather), mixed gas, and cave diving. His teaching combines technical mastery with practical exploration, offering personalized coaching and safety-driven skills built around mastery, not just certification. Learners benefit from his vast experience in deep, overhead, and decompression environments and gain insights from an instructor who is an innovator in both dive technology and exploration.
