Technical Extended Range
The SSI Technical Extended Range Diving course builds on the skills and techniques you learned as an SSI Extended Range Trimix Diver. During this course, you will go beyond no-decompression limits by increasing your dive depth and duration. Using technical equipment and an XR Sidemount or Twinset Total Diving System, the Technical Extended Range Diving course provides enthusiastic underwater explorers with the training necessary to independently plan and conduct mixed-gas dives with unlimited decompression down to a depth of 60 meters. Upon completion of this course, you will receive the SSI Technical Extended Range certification.
