Extended Range

A-1 Extended Range Program in Denver

Why take this course?

The Extended Range course picks up where Extended Range Nitrox leaves off and takes your training as a tec diver further and deeper. Extended Range qualifies divers to make extended no stop dives, and accelerated decompression dives to a maximum of 150ft using nitrox mixtures of up to 100%.

You’ll learn to make gas switch, extended no-decompression dives using air and enriched air to 150 feet, prepare for and respond to foreseeable technical diving emergencies, and master the basic skills and procedures you’ll need as you move into deeper technical diving.
