A nitrox insructor.


Nitrox enables divers to lengthen no-decompression profiles so that they can spend more time in the water. The increased oxygen content reduces nitrogen loading, shortens required surface intervals, reduces post-dive fatigue and gives an added safety buffer for your dives. 

Nitrox Enriched Air courses can be completed at Divetech in a half day class, or you can complete the Nitrox eLearning online prior to arrival and then finish up with the practical part when on-site. Once you finish the nitrox academic portion, Divetech will be ready to take you nitrox diving and issue your certification card. You can register for the eLearning by clicking the button below.

The Nitrox certification course with Divetech includes a manual, instruction, certification fee, and 2 free nitrox tanks.
