Nitrox Diving Specialty Course
Experience increased safety and longer bottom times with Enriched Air Nitrox.
Your Nitrox certification is good world-wide!

Class Info
Nitrox is Oxygen Enriched Air. The gas is ultra-purified, making it much cleaner than compressed air. The result is a breathing gas that is 50 times cleaner than conventional SCUBA compressed air (ever taste oil vapors in your air?).
The major benefit from breathing Nitrox while diving comes from the decrease in nitrogen in your breathing gas. As us divers know, nitrogen is the main culprit behind decompression sickness and nitrogen narcosis. By breathing a gas with less nitrogen (and more oxygen) a diver can expect to have a much larger safety margin, and many other benefits, such as:
-
less nitrogen narcosis
-
less post-dive fatigue
-
extended no-decompression limits, sometimes as much as two to three Repetitive Groups
Many divers even report being warmer on their Pacific Northwest dives!
Silent World has been involved with Nitrox since 1990; we were one of the first dive operators in the state to offer Nitrox. We have the experience and service to help you get involved with this new boon to safer diving.
