duikcomputer

Duikcomputer, often called a diving computer in English, is a compact electronic device worn on the wrist or mounted on a console that assists divers in planning and monitoring a dive. It continuously records depth and time and uses a decompression model to calculate remaining no-decompression time and required decompression stops. By computing tissue-loading and ascent constraints in real time, it replaces traditional dive tables for most recreational dives.

Most duikcomputers use sensors to measure depth and, in many models, temperature. Many devices also support nitrox or other gas mixtures, and some are air-integrated, displaying cylinder pressure or gas duration. User interfaces vary, but common features include alarms for excessive depth or rapid ascent, customizable display layouts, and a log of past dives.

Algorithms: Diving computers rely on decompression models, such as Bühlmann-based RGBM variants, to estimate inert gas uptake in multiple tissue compartments. Some devices allow users to choose between different algorithms or to tune gradient factors. The computer updates calculations as the dive progresses and during ascent, and it may adjust no-decompression limits accordingly.

Usage and limitations: A duikcomputer is a tool to aid dive safety, but it does not guarantee safety. It relies on accurate depth readings, proper maintenance, and correct gas settings. Sensors can fail, batteries can die, and unusual situations may require manual decision-making. Divers should remain trained to plan dives using tables or a computer and to respond to alarms.

History: Commercial diving computers emerged in the 1980s as an alternative to dive tables, evolving to support multiple gases, more models, and improved algorithms. Today they are standard equipment for most recreational divers and are increasingly used in technical diving as well.
