First step: Buoyancy Control & Perfect Trim
Extended Range Gasblender
Correctly mixing gasses is essential to being able to breathe safely underwater. The SSI Gas Blender program teaches you the skills and concepts required to safely blend nitrox and helium-based trimix gases. This non-diving program is open to certified and uncertified divers and teaches proper usage of mathematics, gas blending software, physics, and techniques required to blend breathing gases safely.
​Requirements: 18 years
​
​
Extended Range Foundation
This program offers you a workshop to enhance your skills in using the Extended Range Total Diving System and advanced-level procedures. All training dives are conducted in confined open water at depths below 12 meters. Upon completing the program, you will receive the SSI Extended Range Foundations certification.​
​​​​
Requirements: 16 years, OWD, 24 dives

​
Extended Range Sidemount
Exploring overhead environments like caves and wrecks is an exciting endeavor. However, squeezing traditional dive equipment into the tight spaces found within these areas can be challenging. Improving your diver trim and streamlining by using a sidemount configuration allows you to explore more constricted places than ever before.
The Extended Range Sidemount program trains you to dive in a sidemount configuration, and the techniques required to use multiple stage cylinders carried for decompression diving efficiently and effectively. You will earn the SSI Extended Range Sidemount certification after completing this program and can then apply that configuration to all other XR Programs.​

EXTENDED RANGE NITROX
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.
​
Requirements: Deep Diving Certification, Enriched Air Nitrox 40 Certification, 24 dives
+ for Sidemount Divers: Recreational Sidemount Diving Certification
