The SSI Extended Range Foundations program, or XR Foundations, provides you with a workshop environment to improve your skills to a high level using a selected Extended Range Total Diving System and associated procedures. This program can be used as a class/pool or class/pool/pond program depending on the season, your needs, and configuration requirements. The purpose of the Foundations program can be defined in multiple ways depending on your needs.

 

Enhancement Workshop

This program can be used as an enhancement workshop for CCR, twinset, or Sidemount divers to advanced their trim, buoyancy, and skill abilities beyond their current level.

Technical Skills Update

This program can also be used as a technical skills update or refresher for divers to reacclimate to their equipment configuration and skillset after being away for a period of time.

Tech Diving Primer

The program can also be used as a primer to introduce divers to twinset equipment and practices if they have never used them before but were interested in gaining experience before committing to an XR level program.

 

We do not recommend using this program as a primer into CCR or sidemount diving as the CCR and sidemount diving equipment configurations require significantly more time and training to build comfort and confidence. In that case, we recommend the CCR Diving or Sidemount Diving programs.
