Dive Computer
A Dive Computer (pronunciation: /daɪv kəmˈpjuːtər/) is a device used by scuba divers to measure the time and depth of a dive. In addition, it calculates a safe ascent profile, taking into account the amount of gas in the diver's scuba set, the decompression stops needed, and the time it takes to ascend.
Etymology
The term "Dive Computer" is derived from the words "dive", which means to plunge into water, and "computer", a device that performs high-speed mathematical or logical operations or that assembles, stores, correlates, or otherwise processes information.
Function
A Dive Computer provides real-time depth, dive time, and decompression status, allowing divers to avoid decompression sickness. It also includes a dive planner for planning future dives. Some models include additional features such as air integration, digital compass, and gas switching between different gas mixes.
