The SSI Extended Range Nitrox program provides a thorough introduction to the concepts, techniques, and procedures required for decompression diving with nitrox.

Designed as either a stand-alone program or a stepping-stone to become an SSI Extended Range Trimix diver, this enriched air diving program provides foundational skills that are the basis for all future technical programs.

Using either a sidemount or twinset configuration, this program prepares you to plan and conduct limited decompression dives to a maximum depth of 40 meters.

In addition, this advanced program will teach you the techniques and procedures for using breathing gases up to 100% oxygen for decompression.
