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 "no time left"
Preferences of different people
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 may prefer to use one type of computer over another, as it provides 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 helps you to stay underwater safe. 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. The calculations are not difficult to understand, but it's important to be familiar with the range of your computer's liberal-conservative bias. A liberal-leaning dive computer is the best option if you want maximum bottom time and 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. Some computers have extra features like compass direction and temperature that may be useful for divers. 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
Dive computers use a range of algorithms to calculate decompression times. Although acceptable DCS is between two and five percent, these numbers can vary depending on individual vulnerability and accidents. The US Navy and commercial diving communities often aim for a 0.1 percent mild to 0.025% serious DCS. To ensure maximum safety, a divecomputer must always be capable of correctly running decompression algorithms. However, diving with a dive computer may not be as simple as it seems.
Cost
You must choose the correct diving computer to suit your needs. This will help you avoid any potential accidents. These devices use algorithms which determine how long a diver is able to 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. 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.
