A dive computer will provide the main piece of information, which is the no stop limit. A computer program will factor in depth and air, and calculate the limit. This program will then provide data on when to decompress or begin ascent. This data is also known to be the "no stopping time remaining".
Preferences of divers
Although there are many differences in the functions of different dive computers, they all perform the same basic functions such as tracking nitrogen loading and ascent rate and displaying the depth. Divers may choose to use one type of dive computer instead of another because it gives different NDL times. The settings that are recommended for one computer might not be appropriate for another. Therefore, it is important to plan a dive before purchasing a dive computer. Also, compare various models before deciding which one is best for you.
Functions
A dive computer is designed to help you stay safe when you're underwater. It calculates based on your information. Next, it compares that information to the dive tables in order to calculate how much time you have at sea. The calculations are not difficult to understand, but it's important to be familiar with the range of your computer's liberal-conservative bias. If you want to maximize your bottom time while building safety in the process, a liberal-leaning computer will be the right choice.
Display
The dive computer's display screen, whether mounted on a wrist-mounted pressure gauge or mounted on a submersible water gauge, provides data that can help to avoid decompression. Some computers have extra features like compass direction and temperature that may be useful for divers. Many dive computers allow users to download their data onto a personal computer. This can be useful for accident investigators. These features can make a divecomputer invaluable, especially for investigating the cause of an accidental accident.
Safety limits
Diver computers can calculate decompression times using a range algorithm. The acceptable DCS levels range from two to five percentage, but they can vary depending upon individual susceptibility or accidents. The US Navy and commercial diving communities often aim for a 0.1 percent mild to 0.025% serious DCS. A dive computer should always be able to run the decompression algorithms correctly to ensure maximum safety. However, diving with a dive computer may not be as simple as it seems.
Prices
It is crucial to choose the right dive computer for you in order to avoid any diving accidents. These devices use algorithms to determine how much time a diver can stay underwater. While the algorithms for most dive computers are very generic, divers will have their own unique body composition or fitness levels. Some machines will recommend a greater number of stops than others. Some machines will recommend more no-flys than others. No matter which dive computer you choose it will enable you to stay underwater longer and less likely to get decompression sick.
