The waters are calm, temperate
and comfortable. The visibility is the best you have ever
experienced. It's that perfect day; you know the one that
becomes a part of your "best dive day" stories.
You glance down at your dive computer, then up at your buddy
with a big regulator smile and you give him the Okay. There's
no need for words, you both know this dive isn't going to
end anytime soon. You are both diving with enriched air nitrox.
Enriched air nitrox is a great tool to help you enjoy longer
dives. Enriched air makes this possible because it contains
less nitrogen and a higher percentage of oxygen than normal
air. This means that you absorb less nitrogen as you dive,
giving you longer no decompression limits.
Are you ready to take the next step in your scuba diving experience?
Continuing your training is one of the best steps you can take
to become a safe and educated diver.
In this course you will:
- Be able to stay underwater longer
- Be able to get back into the water sooner
- You will learn about enriched air dive planning
- Care
for equipment
- Hazard management
- Use and application of
enriched
air
- Learn additional skills
- Have a great time!
