Nitrox

with Hydronauts

DEFY GRAVITY

Nitrox is a breathing gas with a higher concentration of oxygen than normal atmospheric air. Diving on Nitrox offers the benefit of staying at certain depths for a longer period of time by extending your no decompression limits (NDL). 

Diving on Nitrox is especially advantageous when doing multiple dives in a day or short period of time. For example, many people take the Nitrox diving course ahead of diving on a liveaboard trip where four or five dives are offered each day. 

Diving on increased oxygen content presents its own physiological and logistical risks. Taking the Enriched Air Nitrox course teaches you about these risks and how to mitigate them. 

We recommend combining the Nitrox course with Explorer 30 and/or Deep 40.

This course can be conducted in two ways:

1. Theory only – 1 Day – 5,500 THB

2. Theory + 2 Open Water Dives – 2 Days – 8,000 THB

Requirements

Must be 15 years of age or older.

Must be a certified Open Water diver. 

Have a minimum of 8 hours logged underwater in an Open Water environment.

If you’re not sure you meet these prerequisites or if you need to complete a prerequisite course, reach out to us.
