A computer diving, which is better known as a dive computer is a digital camera that can make the task of managing nitrogen without requiring the diver to have a watch or a dive table. As a combination of a timer and a depth gauge and some software intelligent calculates the absorption of gas, computer diving is a popular device that is used by more experienced divers.

It is very necessary for divers to find remains and nitrogen decompression and May this also be done by the dive tables manual, but the computer scuba diving is much more advantageous because it can greatly enhance the diving experience with automating the management of nitrogen.

In reality, the computer diving will not plan a dive to the diver underwater, which is always solely responsible for the proper planning and safe in accordance with health guidelines. On the other hand, the computer of scuba diving will be able to keep track of depth and time spent under water, calculate the amount of nitrogen that the body of a diver contains divers and alerts when those levels get too high and also helps the diver to take appropriate decompression stops whenever necessary.

What Happens
When the diver makes a diving traditional, there are only two variables that are used to describe the dive and it is the maximum depth and time. When we calculate the amount of nitrogen absorbed one assumes that the diver was immediately plunged to a maximum depth and stayed there for a while before returning to the surface.

In such cases, the profile of the dive is called square because when graphed on an XY axis, for example, produced as a rectangular trench. However, in reality, diving is not like that and diver descended slowly swim and change in depth to find its way into coral formations or down, then slowly return to the surface.

The main advantage of a diving computer is that it results longer and dive tables with a square profile for the most conservative with excessive absorption which tends to lean toward the safe side. However, the computer diving allows a profile curve and allows regularly to the diver to remain submerged for long periods of time.

Therefore, before choosing a dive computer it may also be wise to check the make and model and check if the batteries easy to change, and the interface is easy to read computer and is it against the light or not?
