TECHNICAL EXTENDED RANGE TRIMIX
The SSI Technical Extended Range course program builds on the skills and techniques learned as an Extended Range Trimix Diver. During this course, you will go beyond the no-decompression limit, increasing both the depth and duration of your dives. Using technical equipment and either an XR Sidemount or a Twin-Tank Full-Body Diving System, the Technical Extended Range course provides avid underwater explorers with the training necessary to independently plan and conduct gas-mix dives with unlimited decompression to depths of 60 m.
