Technical Extended Range

A-1 Technical Extended Range Program in Denver

Why take this course?

The Technical Extended Range Diver course completes your training as an entry-level tec diver, taking you past the limits of recreational diving.

After successful completion of the Technical Extended Range Diver course you’ll be able to independently conduct actual gas switch, decompression dives using air, enriched air and oxygen to a depth of 50m/165 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.
