Technical Extended Range Trimix

A-1 Technical Extended Range Trimix Program in Denver


Why take this course?

The Technical Extended Range Trimix Diver course takes you to new lows as a tec diver, beyond the limits of Technical Extended Range.

After successful completion of the Technical Extended Range Trimix Diver course you’ll be able to independently conduct actual gas switch, decompression dives using trimix, enriched air and oxygen to a depth of 60m/200 feet. You’ll use decompression software to create custom dive tables and plan your dives. You’ll also understand the hazards and risks involved in technical diving, as well as how to prepare for and handle reasonably foreseeable technical diving emergencies.
