If you think that scuba diving is all about attaching an oxygen tank in your back and breathing through it with the use of a regulator, then you are wrong. There’s a lot more to scuba diving than that. In fact, pure oxygen is never used in scuba diving, especially on deep sea diving.
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.

Most people that are laid back are those who gets satisfaction in life by simply having a job, family, and simple thrills. However, there are also those who want to make the most out of life.

If you are such a person, then you will find that deep sea diving can offer you the thrill, adventure and excitement that you have been looking for.
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.
