In recreational diving, air is commonly used and not pure oxygen as most people assume. Air is basically composed of 70 percent nitrogen and 30 percent oxygen. However, nitrox mixes are now being used a lot more in recreational diving as it decreases the chances of nitrogen sickness. Although nitrox is still composed of nitrogen and oxygen, the oxygen concentration is a lot higher than air. This will reduce the risk of nitrogen sickness or bends, but it trades off depth. The more oxygen there is in your scuba diving tank, the shallower you are allowed to dive.

So, just why is pure oxygen not used in deep sea diving? This is because of oxygen toxicity. As you go deeper underwater, the pressure increases and oxygen toxicity becomes a factor. So, by reducing oxygen in the air you breathe, you will be able to go deeper. However, by doing so, you will also increase the amount of nitrogen in the air you are breathing which can result in nitrogen narcosis when you go deeper as well as nitrogen sickness or the bends.

You may wonder how deep sea divers go deep underwater.

The answer to this question is trimix. Trimix is a special air mix designed for deep sea diving. Trimix is composed of oxygen, nitrogen and helium hence the term trimix.

Helium is used because it reduces the proportions of nitrogen and oxygen. This means that because the oxygen is reduced, it will enable the diver to dive deeper. And, because nitrogen is reduced, the diver
will not experience nitrogen sickness or nitrogen narcosis.

The great thing about helium is that it can be breathable under pressure and it has very little narcotic effect. Because of helium’s low density, it reduces breathing resistance at depth or at pressure.

Also, helium does not enter slow tissues as readily as nitrogen, which causes the bends.

The only disadvantage of helium is that it conducts heat 5 times faster. Also, during descent, deep sea divers suffer from a condition called hyperbaric arthralgia.

If you become a deep sea diver, you will learn about the different variations of trimix. Some will be named trimix 10/70 and etc. If you come across with trimix 10/70, it will mean that the gas inside the scuba diving tank will be composed of 10 percent oxygen, 70 percent helium and 20 percent nitrogen. This kind of mix is suitable for dives up to a hundred meters or 330 feet.

These are the things that you have to remember about trimix. As you can see, deep sea diving is not as simple as it may seem. There are so many aspects in deep sea diving that you have to be aware of and one
of them is the gas used for breathing.

So, before you don your scuba diving gears and you plan on going very deep, keep in mind that deep sea diving is a specialty course that one needs to take before they undertake dives like this. Deep sea diving
is different from recreational diving. It takes years of training and a lot of discipline.

Deep sea diving is a different kind of diving. Commonly referred to as technical diving in recreational diving, this kind of diving requires special skills and training in order to be done properly. Although scuba diving can provide you with a window to look at the wonderful world underwater, deep sea diving can offer you more. Here, you will be able to explore more than just colorful reefs. You will also experience having a first hand look at places where few people have been.

From caves located deep underwater to famous shipwrecks, deep sea diving or technical diving can indeed offer you a one of a kind experience. Also, you will be able to look at marine life that can never be seen on shallower parts of the ocean. In technical diving, you will be able to have a chance to be able to be one of the select few to explore the deep parts of the ocean.

So, what do you need to do to become qualified for technical diving?

First of all, you have to remember that technical diving requires special training. In most scuba diving agencies, such as PADI or NAUI, you will find that technical diving courses are readily available. However, you first need to get certified as an open water diver as well as an advanced open water diver.

In advanced open water, you will find a series of sub courses or specialty courses that you can take. Some are for underwater photography, and you will also seetechnical diving as part of the course. You can take several courses if you want to improve your skills on your chosen field. For example, if you take technical diving, you will be able to learn how to dive deeper underwater. However, you can also take underwater photography courses where you will learn how to take great photographs underwater.

By combining these two, you will be able to go deep sea diving and at the same time, immortalize this experience with underwater photography.

Deep sea diving or technical diving can be dangerous. This is the reason why training here is rigorous. Here, you will breathe special gas mixture, particularly the trimix, and you will also learn about the ways on how to deal with fatigue, as well as dangerous scuba diving conditions that can affect your body, such as nitrogen narcosis and decompression sickness.

Although there are dangers in deep sea diving, you have to consider that few incidents occur thanks to the rigorous training. Technical divers have scuba diving skills that are superior to that of the open water diver. So, if you want to experience an adventure that you can never find anywhere else on the planet, then deep sea diving is for you.

If you are already an advanced open water diver, then you will see that you will be able to qualify for deep sea diving. First of all, you need to remember that in deep sea diving, different gases are used for breathing unlike in your average recreational diving where nitrox and air is used you will see that deep sea diving will require a different gas mixture, which is called trimix.

The equipments here are also different. You have to remember that the deeper you go underwater, the colder it will be. Your regular neoprene wetsuit is not enough for you to survive deep sea diving. For this, you will be needed a dry suit. Deep sea diving also requires extreme discipline and concentration. The fact that narcosis can disorient you whenever you go diving, you have to memorize every movement by heart in order for you to avoid making a mistake that can injure you or mistakes that can be fatal.
