what's up guys I'm John owner and
instructor here at Black Flag Dive
Center and today I'm here to talk to you
about why you should bundle your nitrox
certification with your Open Water
certification we get the question all
the time okay well tell me John what's
what's the advantage there well first of
all let's talk about what nitrox is okay
nitrox is a gas mixture where the
percentage of oxygen is greater than it
would be if you were breathing air so
for instance air is composed of about 21
oxygen and 78 or 79 nitrogen when you
increase the amount of oxygen in the mix
you also decrease the amount of nitrogen
in the mix
our bottom times as divers
are determined by how much nitrogen we
in gas during a dive okay so if there's
less nitrogen in the mix for you to in
gas then you will in gas less nitrogen
over the course of a dive okay so what
does that mean for us well essentially
that means that we can have longer
bottom times I don't know about you but
when I pay my hundred dollars hundred
and twenty dollars whatever the fee may
be to get on a boat I'm paying for my
underwater time because I want to see
Fish and swim with Turtles as much as
possible that's Advantage number one
advantage number two is shorter surface
intervals okay so when we're out for a
day of diving when we are done with the
dive we have to sit on the surface and
allow our bodies to off gas some of that
nitrogen before we hop in again
well if you've in gas less nitrogen over
the course of a dive then you have less
nitrogen to off gas in between Dives
that's Advantage number two Advantage
number three is going to be less fatigue
after diving okay so how does that
happen well have you ever seen an
athlete on the sidelines during a
football game in between sets or Downs
okay what are they doing on the
sidelines they're over there with a mask
on breathing Puro two why do they do
that because it reduces fatigue and it
allows them to perform at their Peak
levels
okay so a lot of divers out there when
you ask them hey what what is one of the
main advantages of breathing nitrox
they're going to tell you that well
feel less fatigued after a dive when I'm
breathing nitrox as opposed to when I'm
breathing air
okay that's Advantage number three when
you bundle your nitrox certification
with your Open Water certification
through Black Flag Dive Center you also
receive a hundred dollar discount simply
because it's bundled together
I hope that that clears up some of your
questions and we look forward to seeing
you soon thanks a lot

1. SAFETY
Less nitrogen in your body reduces the chance of decompression sickness (DCS), improving your overall diving safety.
The absorbed nitrogen is the main cause of this disorder in which the nitrogen dissolved in the blood and tissues by the high pressure forms bubbles as the pressure decreases.
Symptoms can include fatigue and pain in muscles and joints.
2. EXTENDED BOTTOM TIME
Recreational Nitrox which may contain anything between 21 and 40 percent of oxygen, has a lower percentage of nitrogen than air. This allows divers to extend their no-decompression limits/ dive time by reducing the amount of nitrogen that is absorbed. The less nitrogen there is in a diver’s breathing gas, the lower his nitrogen absorption will be at a given depth.
For example, on a deep wreck dive, If you dive on air your maximum bottom time on a wreck located at 24m/ 78ft will be around 29 minutes. Diving with Nitrox enables you to remain for about 42 minutes at the same depth, keeping in mind your air-consumption.
3. SHORTER SURFACE INTERVALS
A Nitrox diver absorbs less nitrogen for a given depth and dive time than a diver who uses air. This means that that diver has less nitrogen to off-gas during a required surface interval, which can drastically shorten it.
4. LONGER REPETITIVE DIVE TIMES
If a diver engages in more than one dive per day, Nitrox becomes particularly useful. The diver will have a longer allowable bottom time on a repetitive dive than a diver using air, as he has absorbed less nitrogen.
5. REDUCED EXHAUSTION
Many divers report a significant difference in alertness after a dive with Nitrox. They claim to be less exhausted than after a comparable dive on air, which may be caused by the lower absorption of nitrogen.
6. PRICE!
When you bundle your Nitrox certification with your open water certification, you save $100!
