A computer dive computer supplies the only piece of information that is important: the no-stop limitation. 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 as the "no stop time remaining."
Divers' 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 to use one type of dive computer instead of another because it gives different NDL times. Divers may choose to use a different type of computer than what is recommended. You should plan your dives before purchasing a diving computer. Compare the different models and decide which one works best for you.
Functions
Dive computers are designed to keep you safe 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. 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 dive computer is the best option if you want maximum bottom time and 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. A few dive computers also allow users to download data to their personal computers, which could be very useful to accident investigators. The features of a divecomputer can be invaluable in determining the cause and other purposes.
Safety limits
Diver computers use a range algorithms to calculate decompression rates. 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
You must choose the correct diving computer to suit your needs. This will help you avoid any potential accidents. These devices use algorithms to determine the maximum time a diver can stay under water. The algorithms of most dive computers are fairly generic, but each diver will have slightly different body composition or fitness levels. Therefore, some machines will recommend more stops than others. Some machines will recommend more no-flys than others. You can stay underwater for longer with any dive computer, regardless of what brand.
