This non-qualification program refreshes a diver’s knowledge and practical skills after a period of inactivity on a specific rebreather unit. It is also utilized to update certified divers on manufacturer hardware/software upgrades or to verify skill proficiency and technical knowledge prior to beginning a higher-level CCR training course. Upon successful completion, divers may request a…
This program trains rebreather divers to conduct technical dives to depths between 130 fsw (39 msw) and 200 fsw (60 msw) without using air as a primary bottom gas below 130 fsw. It focuses on the application of normoxic helium-based gas mixtures (Trimix) to mitigate narcosis and gas density issues during technical rebreather operations. Program…
This course upgrades certified CCR Normoxic Trimix Divers, training them to independently plan and conduct technical rebreather dives with mandatory decompression using setpoints up to $1.3\text{ PO}_2$ and normoxic helium-based gas mixtures down to a maximum depth of 233 fsw (70 msw).

This course trains CCR Advanced EANx Divers (or higher) to safely plan and execute rebreather cave or mine penetration dives while navigating the main tunnel. It introduces extended penetration management, complex line work along the main baseline, and accelerated decompression procedures using closed-circuit rebreathers. Program Specifications Course Structure The IANTD Philosophy Wherever you want to…
This program trains rebreather divers in advanced cave penetration and exploration techniques beyond the main line, including complex navigation (jumps, gaps, and traverses). It covers gas management strategies for overhead rebreather operations, lost line and lost diver procedures, and the application of Enriched Air Nitrox (EANx) and oxygen for decompression bailouts. Program Specifications Course Structure…
