TDI Advanced Nitrox Course
Your first Technical Diving Course. Learns the Ins and Outs of using optimized Enriched Air Nitrox. Learn how to use several gas "flavors" to get the most out of your dives and bottom time.
(Many student-divers commonly take Advanced Nitrox with Decompression Procedures)

Class Info
Take your experience using Nitrox to the next level with this course. We spend a fair amount of time going over the formulas behind the charts (and computers) most divers use, then how to plan to use the best mixes, up to 100% oxygen, to maximize your dives.!
Silent World has been involved with Nitrox since 1990; we were one of the first dive operators in the state to offer Nitrox. We have the experience and service to help you get involved with this new boon to safer diving.
