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 to be the "no stopping time remaining".
Preferences of divers
While there are many differences between dive computers, most have the same basic functions. These include displaying depth, tracking Nitro loading, ascent rate, and logging the dive. Divers might choose to use a different type of computer because they have 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 helps you to stay underwater safe. 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. Although you don't need to be an expert in math to understand the calculations, it is helpful to have a general idea of where your computer falls within the liberal-conservative spectrum. A liberal-leaning computer can help you maximize your bottom time and improve safety.
Display
The display screen of a dive computer can be mounted on a pressure gauge or wrist, and provides information that will help you avoid decompression while diving. Some computers have extra features like compass direction and temperature that may be useful for divers. Some dive computers even allow users to download their data to a personal computer, which may be helpful to accident investigators. With these features, a dive computer can prove invaluable for a number of purposes, including determining the cause of an 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, commercial diving and other organizations often strive to achieve DCS levels of 0.1 percent or 0.025%. 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.
Prices
To avoid accidents when diving, it is important to select the best dive computer. These devices use algorithms to determine how much time a diver can stay underwater. Although most computers use the same algorithms, each diver's body composition and fitness levels will be different. Some computers will recommend more stops than others. Some will recommend more stop options than others. 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.
