A dive computer will provide the main piece of information, which is the no stop limit. 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 information is also called the "no stop remaining" data.
Different 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 prefer to use one type of computer over another, as it provides different NDL times. The settings that are recommended for one computer might not be appropriate for another. It is important to plan your dive before purchasing a computer, and to test them out before you decide which model will be 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. It doesn't take a genius math mind to understand the calculations. However, you should have an idea of where your diver computer falls on the liberal-conservative spectrum. A liberal-leaning computer can help you maximize your bottom time and improve 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. Divers may find it useful to have additional features such as water temperature and compass direction. Dive computers can even be used to save data to a personal computer. This may prove useful for accident investigators. These features make a dive computer invaluable, and can even be used to determine the cause of an accident.
Safety limits
Dive computers use a range of algorithms to calculate decompression times. The acceptable DCS numbers range from 2 to 5 percent. However, individual susceptibility and accidents can affect the figures. 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. Divers may find it difficult to use a computer to dive.
Cost
Choosing the correct dive computer for your needs is essential to prevent any accidents while diving. These devices use algorithms that determine how long a diver can remain underwater. Although most computers use the same algorithms, each diver's body composition and fitness levels will be different. Therefore, some machines will recommend more stops than others. Others will recommend a greater number of no-flys. Whichever dive computer you choose, it will help you stay underwater longer and reduce the risk of decompression sickness.
