The no-stop limit is the most important piece of information a dive computer provides. 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".
Different preferences
There are many differences among different dive computers. However, all of them perform the same basic functions like displaying depth and tracking nitrogen loading. Divers may prefer to use one type of computer over another, as it provides 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 helps you to stay underwater safe. It performs calculations based upon your information. Then, it compares this information with the appropriate dive tables to determine your depth time. You don't have to be a math genius to understand the calculations, but you should have a good idea of where your dive computer falls on a liberal-conservative spectrum. A liberal-leaning computer can help you maximize your bottom time and improve safety.
Display
A dive computer's screen can be worn on the wrist or attached to a submersible pressure gauge. It provides all necessary information to prevent decompression and ensure safe diving. Divers may find it useful to have additional features such as water temperature and compass direction. Some dive computers even allow users to download their data to a personal computer, which may be helpful to accident investigators. The features of a divecomputer can be invaluable in determining the cause and other purposes.
Safety limits
Diver computers employ a variety of algorithms to calculate decompression times. While the numbers for acceptable DCS range from two to five percent, they vary based on individual susceptibility and accidents. The US Navy and the commercial diving community often wish to achieve 0.1 percent mild or 0.025 percent serious DCS. For maximum safety, a divecomputer should be able run decompression algorithms correctly. 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 which determine how long a diver is able to stay underwater. Most dive computers use the same algorithms but every diver has a different body composition and fitness level. Some computers will recommend more 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.
