Are you eager to extend your underwater exploration? Whether you're a scientific diver or a photographer seeking more time beneath the waves, the TDI Advanced Nitrox Course offers a compelling opportunity. This course empowers divers to utilize enriched air nitrox ranging from EAN 21 to EAN 100 percent within their current certification level, allowing for dives up to a maximum depth of 40 meters/130 feet without the need for staged decompression.
Often paired with the TDI Decompression Procedures course, the Advanced Nitrox Course serves as the cornerstone of your technical diving journey. It provides a solid foundation for those looking to advance their skills and capabilities in the world of technical diving. Notably, TDI Advanced Nitrox is essential for both SCR (Semi-Closed Circuit Rebreather) and CCR (Closed Circuit Rebreather) divers, adding versatility to its significance.
