Technical Extended Range SSI program

The Technical Extended Range diving program builds upon skills and techniques learned as an SSI Extended Range Diver. During this 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 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 50 meters.
