It’s not easy to reach this level and earning your SSI Technical Extended Range certification opens the door to deeper diving expeditions.  You can now continue on to complete TriMix training.

Successful candidates will not only be qualified to conduct decompression dives to a max depth of 50m, but more importantly, the course builds on skills learnt on the previous courses, so you will be comfortable using twins, but now will be managing TWO stage decompression gases.  You can then begin the SSI  Technical Extended Range Trimix course.
