Extended Range

Extended Range diving opens up a variety of aquatic environments, increases your dive depths limits, and extends your bottom times. The SSI Extended Range program is the core program that all other open-circuit XR programs are built upon.

If you've never worn a twinset before, then the Extended Range Foundations Class is highly recommended.
