Advanced Nitrox The objective of this course is to train divers in the benefits, hazards and proper procedures for utilizing EANx21 through EANx100 for dives not requiring staged decompression (Decompression techniques may be combined with this course). The TDI Advanced Nitrox Program is not for everyone....we do not accept all ca... Find Out More

Decompression Procedures The objective of this course is to train divers how to plan and conduct a standard staged decompression dive not exceeding a maximum depth of 150 feet. The most common equipment requirements, gear setups, decompression techniques and decompression mixtures (including oxygen and nitrox) are presented. Find Out More

Solo Diver We realize that many divers dive by themselves, but this in no way makes them "solo divers". They are neither trained nor knowledgable in the hazards to which they may be exposing themselves. The SDI Solo Diving course examines the benefits, hazards, and proper procedures for planning and conducting solo dive... Find Out More
