A dive computer will provide the main piece of information, which is the no stop limit. A computer program will consider depth and air to determine the limit. The program also provides data on when to ascend or stop. This data is also known "no time left"
Preferences of different people
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 choose one type of diving computer over another due to the fact that it offers different NDL times. Divers may choose to use a different type of computer than what is recommended. Before you buy a dive computer, plan your dive and compare the models to find the best one for you.
Functions
A dive computer can help you remain safe while you're under water. 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. 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
The dive computer's display screen, whether mounted on a wrist-mounted pressure gauge or mounted on a submersible water gauge, provides data that can help to avoid decompression. 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. The features of a divecomputer can be invaluable in determining the cause and other purposes.
Safety limits
Diver computers can calculate decompression times using a range algorithm. 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 and the commercial diving community often wish to achieve 0.1 percent mild or 0.025 percent serious DCS. To ensure safety, a dive computer must be capable of running the correct decompression algorithms. However, diving with a dive computer may not be as simple as it seems.
Prices
Diver accidents can be prevented by choosing the correct computer for you. These devices use algorithms in order to determine how long a diver will be able stay underwater. While most diving computers have the same algorithm, every diver is unique. Divers will have different fitness levels and body compositions. Different machines will recommend different stops. Others will recommend more stops. Whichever dive computer you choose, it will help you stay underwater longer and reduce the risk of decompression sickness.
