The no-stop limit is the most important piece of information a dive computer provides. A computer program will take into account depth and air in order to calculate this limit and offer data on when to begin the ascent or decompression stop. This data is also known "no time left"
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 choose one type of diving computer over another due to the fact that it offers different NDL times. Therefore, the settings recommended for a particular computer may differ from those for another diver. You should plan your dives before purchasing a diving computer. Compare the different models and decide which one works best for you.
Functions
A dive computer is designed for safety 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. 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. Liberal-leaning computers are the best for maximizing your bottom time and ensuring 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 dive computers also offer extra features, such as compass direction and water temperature, which may be important to 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 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. A dive computer should always be able to run the decompression algorithms correctly to ensure maximum safety. Diving with a dive computer is not always easy.
Cost
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. Most dive computers use the same algorithms but every diver has a different body composition and fitness level. Some machines will recommend more stops than other. 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.
