Technical Extended Range (Trimix)

The SSI Technical Extended Range Trimix diving program builds upon skills and techniques learned as an SSI Extended Range Trimix Diver. During this Extended Range diving program, you will go beyond the no-decompression limit by increasing your dive depth and duration. Using either a sidemount or twinset configuration, the Technical Extended Range Trimix gas diving program provides avid underwater explorers with the training necessary to independently plan and conduct mixed gas unlimited decompression dives to a maximum depth of up to 60 meters.
