Dive computers allow divers to measure the time and depth of a dive so that an ascent profile can be calculated and displayed, for safety underwater. This means that you can advertently avoid decompression sickness otherwise known as the bends. Dive computers are able to perform a continuous calculation of the partial pressure of gases in the body based on the actual depth and time profile of the diver. As the dive computer measures depth and time accordingly, it is able to provide warning of excessive ascent rates and missed decompression stops.
Most dive computers also provide further information including air and water temperatures, data on oxygen toxicity, a computer compatible dive log and pressure of any remaining breathing gas in your diving cylinder.
There are several variations of dive computer, console mounted, wrist mounted, ACW (advanced computer watch).
In recent years wireless integrated scuba computers have become more common, they 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.
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.
