The course
At this level, what counts most is the experience you bring with you. The SNSI Explorer Diver 3 course is for divers who already master hypoxic Trimix and want to take it further, down to 300 ft / 90 m. You learn to manage longer decompressions, more gases and more complex logistics, working as a close-knit team where every member knows exactly what to do.
