Dive Computers

Our Dive Computer constantly monitors your depth and time to work out how long you can stay in the water without having to consult confusing tables. Scuba diving computers allow divers to extend their bottom time and increase their safety underwater, here is a selection of leading dive computers from manufacturers such as Shearwater, Aqua Lung, Mares, Suunto and other leading diving equipment manufacturers. There are several variations of dive computer, console-mounted, wrist-mounted, ACW advanced computer watch (essentially a wrist watch-sized dive computer). Wireless integrated scuba computers send tank pressure data wirelessly to your computer. The great advantage of having air data is your computer can calculate your breathing rate, so it can monitor how long your air will last but also how hard you are breathing so can adjust your bottom time based on your nitrogen loading. Thanks to miniaturisation in recent years you can now purchase a dive computer the size of a wristwatch. These allow you to wear it both during the dive and afterwards into the evening. This has the advantage that you are unlikely to lose it. Apart from the very entry-level diving computers, most have the option to interface with your PC so you can record your dives and profiles to your computer. A more basic version of a dive computer is the bottom timer which accurately records time and depth but does not calculate no decompression times. Generally, it is accepted that digital dive instruments are accurate within 1% whereas an analogue instrument would be plus or minus 10%.
