The Main Functions of Dive Computers and How to Choose One

dive-computersDiving equipment has improved a lot in the past few years. There are many advanced devices that are designed to make this thrilling sport a lot more safer and enjoyable. One such device is the dive computer which is an essential piece of equipment for both beginners and experienced divers alike. When you’re diving, especially when descending deeper into the water there is more pressure which can cause nitrogen to quickly dissolve into your body’s tissues. When a large amount of nitrogen has dissolved into the body, the diver can experience a condition know as decompression sickness. In many cases this would not have very harmful effects, but there are cases when decompression sickness can cause serious health problems such as paralysis or circulatory shock. That’s why is very important to maintain dissolved nitrogen levels within normal limits to avoid getting decompression sickness. This is where the use of dive computers can make a huge difference

You will need a dive computer to accurately measure the depth and time of your dive. It can provide you with all the necessary information about your decompression levels. As you dive deeper underwater your dive computer will tell you how long you have been diving and calculate the amount of time you are allowed to stay underwater. Dive computers have a practical design and usually look a lot like big digital wristwatches. They serve as handy calculators that make essential calculations about your dive. Taking into account the duration and depth of your dive, the device can calculate the number of decompression stops that you should make and at what depths.

Every advanced dive computer would come with a practical log function that enables the diver to keep track of each completed dive and review information such as how long much time you have spent on a certain dive or at what depths you have been diving. Most dive computers are designed to record and keep the data for up to 10 dives. They can be divided into two main categories: integrated and independent. An integrated model would usually include other types of instruments such as a compass or a submersible pressure gauge. An independent model is designed to serve as a stand-alone pressure gauge that doesn’t include any additional instruments, yet still provides a number of useful information about your dives. Regardless of what model you choose make sure it features a bright display that is easy to read, so you can keep track you dives even in low light conditions. Some other features to look out for include a long battery life, durability and programmable alarms.
