Extended Range Nitrox Course


Have you ever dreamed of having longer no-decompression limits to take pictures or explore a wreck? Did you ever want to be safer while diving concerning the potential risk of decompression sickness? Nitrox is the key. Due to the reduced fraction of nitrogen in your breathing gas, your body will have less work and the desaturation times will be reduced. The Enriched Air Nitrox Diver certification enables you to use Cylinders with a mixture up to 40%. The Extended Range Nitrox Course qualifies you to dive to 40 meters using nitrox mixtures of up to 50%, and 15 minutes of back gas decompression using a one stage decompression gas. The program can be completed wearing your standard total diving system, a large cylinder with H or Y valve or even a full twinset. Extended Range Nitrox is useful to explore our 2 famous ship wrecks or simply on a liveaboard Trip to the south or north. This 3 days course includes 3 boat diving day trips with a total of 6 dives.


Course Description

XR – Nitrox Course

The bridge between recreational and technical diving is narrower than ever before! XR programs are designed to allow you to “extend beyond the recreational limits” without dramatically changing your diving philosophy.
XR programs simply enhance and build upon your existing knowledge, skills and experience. They are taken like a regular SSI Specialty, and can be credited toward your Advanced Open Water or Master Diver.
The training will provide you with the skills to dive safely and with added confidence, giving you the tools to complete limited decompression.

This is the chance you have been waiting for to discover new horizons. We understand decompression is no longer a taboo word, it’s a tool that when used correctly can allow you to experience much more of the underwater world.

Decompression may sound difficult or scary but it certainly is not! Research shows that almost all divers who have been diving for at least two years have completed some kind of decompression dives even without the training. We want to make this process safer by teaching what is happening to the diver’s body, what to do if something goes wrong, and what equipment can make decompression diving safer.
In fact, all dives are decompression dives. It is just the amount of dissolved nitrogen we are prepared to surface with that makes it a so-called “No Decompression Dive”.
As divers, we all complete safety stops. The basics are to attain neutral buoyancy (as we learn in OWD) and stay there for a prescribed amount of time. That’s it, nothing more! We used to be taught that Deco is bad. Well, times have changed and improved equipment and training have allowed us to open the door to all.

The Extended Range Nitrox Diving equivalent to Advanced Nitrox or TecRec Tec 40 Course.
