The no-stop limit is the most important piece of information a dive computer provides. Computer programs will use depth and air to calculate the limit and provide information on when to ascent or decompression. This information is also called the "no stop remaining" data.
Different preferences
Diver computers come in many different forms, but they all have the same basic functions: tracking nitrogen loading, logging dives, and displaying depth. Divers may choose one type of diving computer over another due to the fact that it offers different NDL times. As a result, the recommended settings for a specific computer may be different than those prescribed for another diver. 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 runs calculations based on your information, and then compares that information against the corresponding dive tables to determine how much time you have at depth. While you don't necessarily need to know the formulas, you should be able to identify where your dive computer is on the liberal-conservative spectrum. Liberal-leaning computers are the best for maximizing your bottom time and ensuring safety.
Display
Whether wrist-mounted or mounted on a submersible pressure gauge, a dive computer's display screen provides the necessary data to avoid decompression and ensure a safe dive. Some computers have extra features like compass direction and temperature that may be useful for divers. Dive computers can even be used to save data to a personal computer. This may prove 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. Although acceptable DCS is between two and five percent, these numbers can vary depending on individual vulnerability and accidents. The US Navy and commercial diving communities often aim for a 0.1 percent mild to 0.025% serious DCS. To ensure maximum safety, a dive computer should be able correctly run the decompression algorithm. However, diving with a dive computer may not be as simple as it seems.
Prices
Diver accidents can be prevented by choosing the correct computer for you. These devices use algorithms in order to determine how long a diver will be able stay underwater. While most diving computers have the same algorithm, every diver is unique. Divers will have different fitness levels and body compositions. Therefore, some machines will recommend more stops than others. Others will recommend a greater number of no-flys. It doesn't matter what dive computer you choose; it will allow you to stay underwater for longer periods of time and lower the chance of getting decompression sickness.
