The course
The top of the SNSI technical path, for divers with deep experience behind them. The SNSI Expedition Diver course trains you to plan an extreme dive as a true expedition: choosing the right mixes for every depth, organising team, equipment and support, and managing every phase from descent to the end of decompression, down to 400 ft / 120 m during training. For those who want to explore where few have been.
