What is NITROX?
In diving terminology; any mixture of nitrogen and oxygen, where these two gases represent the major constituents of the gas mix, is termed NITROX. Note that mixes which contain more than trace levels of other gases in addition to nitrogen and oxygen are not NITROX. Air (which is what we breath on land) is considered a NITROX mix. NITROX mixes which are hyperoxic (contain more than 21% oxygen) are variously known as; Enriched Air, Enriched Air Nitrox (EAN or EANx). For the most part, sport divers will only be interested in hyperoxic NITROX mixes.

Why would you want to use NITROX?
The biggest reason you would want to use NITROX is longer No Decompression Limits or NDLs. With this, we get a reduced decompression penalty due to the lower level of nitrogen absorbed during the dive. This may be realized by surfacing according to the NITROX tables or as an additional safety factor by following the standard air tables.

Shorter surface intervals and longer subsequent dives due to the lower residual nitrogen level following a dive. The surface interval is followed for the EAD not the actual depth. Again it may be used as safety padding by following the standard air surface interval. Nitrox provides faster off-gassing than air during decompression. It may be used to reduce the length of the decompression penalty by following a nitrox decompression schedule, or it may be used as padding to increase the safety factor by following an air decompression schedule. This is similar to the use of pure oxygen during decompression. On the surface it also provides an alternative to pure O2 in situations where it is desirable to breath a mix with a higher O2 percentage than air.

The reduced level of nitrogen in your system has also been claimed to reduce the feeling of lethargy or tiredness following a dive, this is thought to be due to a reduction in sub clinical DCS ie a reduction in the number of asymptomatic bubbles in our system after a dive. The following claims are also made of nitrox.

For more info come into the store and ask one of our PADI nitrox instructors about the many different courses which are avalible here.

When i first came to Kho Tao to do my divemaster course at djl, i never imagined i would stil be here 3 years later. But its very easy to get stuck on the rock.
Many peple come here and never leave and im happy say i was one of them.
My time during my DMT course was full of good times. lots of diving, studying and of course drinking. I learnt many new skills, not just diving and also saw my personal confidance grow. It was a challange giving dive boat briefings to 30 people, but it gets easier every time.
After 3 great months of divemaster training i was given the job of divemaster at djl. I worked hard for a year and lost about 3 stone. leading fundivers, carring tanks and again more drinking.
Then finally the next step, time to be come a PADI dive instructor. This was 2 weeks of instructor development with our course director pete, and then 2 stressfull days of instructor exams. Now Im still working at djl and still learning new things everyday, and of course still drinking everyday. But most importantly still loving living on the rock.

We are planning a new project to see how coral grows on different surface materials and at what rate and types. We are planning on making two 1 meter squared boxes, one from iron and one from steel. Each surafce of the box will be different. we will sink the boxes in a set location on Kho Tao and then monitor them weekly for growth rate and coral types.
All customers are welcome to dive our very own DJL reef.
