Is it worth getting a dive computer?
Because of their precision and ability to track your depths, oxygen, and temperature, high-quality dive computers will actually prolong the time you have to dive safely. Displaying dive times, depth and no decompression limits, a dive computer is one of the most important and often most advanced pieces of kit that any diver will own. Choosing the right one will not only help you to get more from your upcoming dives but also ensure that you can dive safely and stay underwater.If the dive computer fails at any time during the dive, the dive must be terminated and appropriate surfacing procedures should be initiated immediately. A diver should not dive for 18 hours before activating a dive computer to use it to control their diving.Bottom Line: If you don’t use a dive computer, you must calculate your dives the good old fashioned way[1] to avoid the danger of decompression sickness (DCS). Besides crunching numbers, dive computers offer many other benefits during and after a dive.The rule suggests that the depth of the dive (in feet) and the time spent underwater (in minutes) should not exceed a combined total of 120. The goal of this rule is to keep divers within a range where they can avoid serious risks such as nitrogen narcosis and decompression sickness.If the dive computer fails at any time during the dive, the dive must be terminated and appropriate surfacing procedures should be initiated immediately. A diver should not dive for 18 hours before activating a dive computer to use it to control their diving.

What is a dive computer?
A dive computer, personal decompression computer or decompression meter is a device used by an underwater diver to measure the elapsed time and depth during a dive and use this data to calculate and display an ascent profile which, according to the programmed decompression algorithm, will give a low risk of . A dive computer is not just a luxury—it’s an essential piece of scuba diving gear for ensuring safe and enjoyable dives. From accurately tracking your depth and dive time to providing decompression and Nitrox information, dive computers are an indispensable tool for divers of all levels.Your computer continuously tells you how much dive time you safely have remaining. Your computer combines a depth gauge, timer and sometimes a submersible pressure gauge (SPG) into a single, useful instrument. The majority of divers have a computer because it makes sense.If you’re diving deeper, say 20–30m, this makes a huge difference. Add nitrox into the mix, and you could even double your bottom time. So if you want to dive longer, safer, and smarter, ditch the tables and get yourself a dive computer!
Do dive computers have GPS?
Satellite connectivity allows our dive computers to automatically mark your dive entry and exit points1 for surface navigation. Our latest dive computers utilize GPS, GLONASS and Galileo receivers for precise location accuracy. Dive computers provide real-time information about your dive, allowing you to monitor your depth, ascent rate, and time underwater. This information helps you stay within safe limits and avoid dangerous situations.Military divers often use swim boards to navigate underwater accurately. These boards typically feature a compass to guide the diver underway. With a DVL mounted on an electronic swim board, divers can track how far they have swum, where they are, and how they can find their way back to their starting point.
