Explorer Diver 1

The course

This is where technical diving really begins. The SNSI Explorer Diver 1 course is the first decompression level: you learn to plan dives with mandatory stops, carry the right gas for every phase and use EAN50 and oxygen to decompress, down to 170 ft / 51 m. Method, redundancy and teamwork become part of every dive, so you can explore further with the right equipment and skills.
