Come Dive the "Good Stuff"!

Why dive Enriched Air/Nitrox? Because it allows you to do more of what you love! Diving with Enriched Air Nitrox allows you to dive longer, safer and more often! By increasing the Oxygen content of your breathing gas, you can stay down longer and safer. With Enriched Air you have a maximum depth that you can go to, so this is perfect for all of our recreational shallow divers!

The Enriched Air Nitrox program will teach you how to safely plan and dive with enriched air mixtures of up to 40% oxygen. Diving with enriched air can increase your no-decompression limits, increase your safety, and reduce the required length of your surface intervals when compared to air. 

All your pre-study will be done online so you can complete on YOUR schedule. Once you are done you will come see us at Outside the Asylum and Travel and we will finish the course by showing you how to obtain and analyze your tanks. 

Want to take that tank for a dive? No worries, just pay for your breathing gas ($15.00 including tank rental) and we will take you for a guided dive that weekend. 

Benefits of Enriched Air/Nitrox 

Longer Bottom Times

Recreational Nitrox (21 - 40% oxygen) contains a lower percentage of nitrogen than air. The reduced percentage of nitrogen in recreational Nitrox allows divers to extend their no-decompression limits by reducing nitrogen absorption.
For example, according to the NOAA (National Oceanographic and Atmospheric Association) no-decompression dive tables, a diver using Nitrox 36 (or NOAA Nitrox II) may stay up to 50 minutes at 90 feet of sea water, while a diver using air may only stay a maximum of 30 minutes at this depth.

Shorter Surface Intervals

A diver using Nitrox absorbs less nitrogen on a given dive than one who uses air. This means that the Nitrox diver has less nitrogen to off-gas during the surface interval, which can shorten the required surface interval drastically. For example, a diver using Nitrox 32 can repeat a 50-minute dive to 60 feet after 41 minutes, while a diver using air must wait a minimum of 8 hours to repeat the same dive (using to NOAA's no decompression dive tables).

Longer Repetitive Dive Times

Nitrox becomes especially useful for divers who engage in more than one dive per a day. A diver using Nitrox will have a longer allowable bottom time on repetitive dives than a diver using air because the diver using Nitrox has absorbed less nitrogen.

For example, after a dive to 70 feet for 30 minutes, a diver using Nitrox 32 can stay at 70 feet for a maximum of 24 minutes if he immediately reenters the water. However, a diver performing the same series of dives on air may only stay at 70 feet for 19 minutes on his second dive (according to NOAA's no decompression dive tables).

Feeling Energized after Diving

Many divers claim to feel energized after a dive on Nitrox than with air. By reducing a diver's nitrogen absorption, Nitrox may also reduce a diver's post-dive exhaustion. This is not a proven fact, but enough divers claim to feel this effect that it is definitely a consideration.


As with all OTA Diving & Travel classes there are no hidden fees in these classes. Class price includes, all electronic/paper manuals and certification costs. Since this is a "dry class" there are no additional charges for this class. If you would like to dive with Enriched air, just pay for your fill, grab your gear and lets go diving!
