XR Nitrox – Advanced Decompression & Gas Switching
The SSI Extended Range Nitrox program is the bridge to true technical independence. This course trains you to plan and conduct decompression dives to a maximum depth of 40 meters, using Nitrox mixtures up to 100% to accelerate your decompression.
Designed for divers who want to stay longer and explore further, you’ll master advanced equipment configurations and technical procedures. By the end of this program, you will be certified to conduct dives with staged decompression stops of up to 15 minutes. This is where you master the art of the "Deco" dive and join the ranks of technical explorers.
