The no-stop limit is what a dive computer gives you. 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 information is also called the "no stop remaining" data.
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 to use one type of dive computer instead of another because it gives different NDL times. A diver may have different settings than the one 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 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. 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
Display screens on dive computers can be wrist-mounted, submersible pressure gauge mounted or both. They provide the information necessary to avoid decompression as well as ensure safe diving. Divers may appreciate additional features like the compass directions and water temperature. A few dive computers also allow users to download data to their personal computers, which could be very useful to accident investigators. These features make a dive computer invaluable, and can even be used to determine the cause of an accident.
Safety limits
Dive computers use a range of algorithms to calculate decompression times. The acceptable DCS levels range from two to five percentage, but they can vary depending upon individual susceptibility or 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 dive computer should be able correctly run the decompression algorithm. Dive computer diving may not be as easy as it appears.
Prices
Choosing the correct dive computer for your needs is essential to prevent any accidents while diving. These devices use algorithms which determine how long a diver is able to stay underwater. While the algorithms for most dive computers are very generic, divers will have their own unique body composition or fitness levels. Some machines will recommend more stops than other. Some will recommend more stop options than others. No matter which dive computer you choose it will enable you to stay underwater longer and less likely to get decompression sick.
