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 to be the "no stopping time remaining".
Different preferences
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 can choose to use one type or another of the dive computers because it has different NDL times. As a result, the recommended settings for a specific computer may be different than those prescribed 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
Dive computers are designed to keep you safe underwater. The computer runs calculations on your data and compares it with the dive tables to calculate how long you have at depth. 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 appreciate additional features like the compass directions and water temperature. 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 employ a variety 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 divers often want to achieve 0.1 percent mild DCS or 0.025% serious DCS. To ensure safety, a dive computer must be capable of running the correct decompression algorithms. Diving with a dive computer is not always easy.
Cost
Choosing the correct dive computer for your needs is essential to prevent any accidents while diving. These devices use algorithms that determine how long a diver can remain underwater. Most dive computers use the same algorithms but every diver has a different body composition and fitness level. Therefore, some machines will recommend more stops than others. Others may recommend more no-flys. You can stay underwater for longer with any dive computer, regardless of what brand.
