A dive computer is an electronic device used by scuba divers to monitor and display dive data in real time. It serves as a replacement for traditional dive tables and gauges, providing a streamlined and often more accurate way to manage critical information during a dive. The primary function of a dive computer is to calculate and display the diver's current depth, bottom time, and ascent rate. Based on this information, it determines the remaining no-decompression limit (NDL), which is the maximum time a diver can stay at a given depth without requiring mandatory decompression stops on ascent.

Dive computers employ algorithms, often based on established decompression models like Bühlmann or Haldane, to manage nitrogen absorption and off-gassing. As a diver descends, the computer continuously tracks the depth and time, calculating the cumulative nitrogen load in the body. Upon surfacing, the computer will indicate if any decompression stops are necessary and, if so, the required depth and duration of each stop to safely off-gas accumulated nitrogen.

Modern dive computers offer a range of additional features. Many include air integration, allowing them to wirelessly monitor the remaining air in the diver's tank and calculate the remaining air time at the surface. Other common features include dive logging capabilities, displaying maximum depth, water temperature, and ascent warnings. Some advanced models can also track multiple gas mixes for technical diving or even incorporate GPS for surface navigation. The use of a dive computer significantly enhances dive safety by providing constant, real-time monitoring of essential dive parameters and automating complex decompression calculations.
