You will find it to be fun, rewarding and a new adventure!
Many years ago this new breathing gas was introduced to the diving industry, and its name was Nitrox. Many divers then and now continue to use and get trained to use it as their primary breathing gas, and there is a long list of reasons why. At the top of that list are: decreased uptake of nitrogen, reduced post-dive fatigue and most importantly, when used properly, increased safety margins. Nitrox has other benefits as well; the basic nitrox course is not your stopping point when it comes to its uses.
Divers usually take nitrox for one of two reasons; the first are the ones already listed, and the second is to begin their progression into the technical realm of diving, a “nitrox crossroads” if you will. Basic nitrox courses cover the use of 22 to 40 percent oxygen and everything in between, but there is another level to nitrox. Technical divers commonly use higher levels of oxygen for what is again a very long list and in some ways it’s similar to what sport divers are looking for. Higher levels of oxygen for technical diver’s means: reduce uptake of nitrogen on decompression stops, to add additional oxygen to the breathing gas while using a rebreather and for those scientific divers, a massive increase in bottom time for shallow depths.
So where does this leave you, the already certified nitrox diver? You are in the perfect position to expand your diving abilities and explore new things by taking the TDI Advanced Nitrox Course! Advanced nitrox is commonly taught in conjunction with TDI Decompression Procedures. While there might be this thought in your mind: “I don’t want to go any deeper,” the truth is you don’t have to. There is a common misconception about decompression procedures that you have to go deep. This is not the case. As a matter of fact, most decompression dives are performed within the sport diving depths. The TDI Decompression Procedures course teaches you the principles, theory and application of decompression diving which allows you, the diver, to make the educated decision if you should plan and perform a decompression dive. Another benefit of taking the advanced nitrox and decompression procedures courses is, should you find yourself in decompression – which is not the ideal situation – you will understand what your dive computer is telling you to do and the reasons behind it.
One thing you need to consider when taking the advanced nitrox course is that any piece of equipment that will be in contact with greater than 40 percent oxygen needs to be O2 cleaned. This primarily means your regulator set and any cylinders you will be using; this is not an expensive or time consuming upgrade and can be done during your regulator and cylinder(s) annual service. Another piece of equipment to think about is a multi-gas dive computer. There are lots of options for these on the market and most will have the ability to perform dive planning and tracking if you are using air, nitrox or helium based gases. The newer computers are very easy to program; you simply set the percentage of oxygen in the cylinder, and the computer does the rest!
So what’s your next step? Contact your local TDI facility and get started! You won’t regret it. Finally, you will get to spend more time on those wrecks you have been diving or spend more time taking pictures. Whatever it is you like to do while you are diving, take the TDI Advanced Nitrox course and do more of it!
