A computer dive computer supplies the only piece of information that is important: the no-stop limitation. The computer program will calculate the no-stop limit by taking into account air depth and air volume. It will also provide data about when to start or stop decompression. This data is also known "no time left"
Divers' preferences
There are several differences between different dive computers, but most do the same basic functions, such as displaying depth, tracking nitrogen loading, ascent rate, and logging the dive. Divers may choose one type of diving computer over another due to the fact that it offers different NDL times. Divers may choose to use a different type of computer than what is recommended. 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 will run calculations using your information and then compare that information with the relevant dive tables to determine how long you have at deep. 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
Display screens on dive computers can be wrist-mounted, submersible pressure gauge mounted or both. They provide the information necessary to avoid decompression as well as ensure safe diving. Divers may also find useful extra features in some dive computers, such as the compass direction or water temperature. Many dive computers allow users to download their data onto a personal computer. This can be useful for accident investigators. The features of a divecomputer can be invaluable in determining the cause and other purposes.
Safety limits
Diver computers can use many algorithms to calculate the decompression time. Acceptable DCS can range from 2-5 percent. But, each person's susceptibility to injury and accident will affect how much they are acceptable. The US Navy as well as commercial divers want to see 0.025 percent of serious DCS. To ensure safety, a dive computer must be capable of running the correct decompression algorithms. 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 which determine how long a diver is able to stay underwater. Although most computers use the same algorithms, each diver's body composition and fitness levels will be different. 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.
