Dykdator

Dykdator, or diving computer, is a device used by divers to monitor depth, bottom time, and decompression status during a dive. It helps manage nitrogen loading and ascent plans by calculating safe limits and stop sequences based on a decompression model. Dykdatorn can be used for recreational dives as well as some forms of technical diving, where multiple gas mixes and more complex decompression schedules are involved.

Most dykdatorer include a depth sensor, a timer, a battery, and a user interface. They typically require input of the gas mix being used (air, nitrox, trimix, etc.) and adjust calculations accordingly. Common decompression models used in these devices rely on tissue- loading concepts or gradient factors to estimate nitrogen absorption and release. The device continuously displays current depth, elapsed bottom time, no-decompression limits, and, if necessary, planned decompression stops for a safe ascent.

Features commonly found in diving computers include alarms for excessive depth, rapid ascent, or exceeding no-decompression limits, as well as battery alerts. Many models offer dive logging, data export to a computer or smartphone, and support for multiple gas mixes or a gauge mode for basic depth-time awareness. Some devices connect via Bluetooth or USB for software updates and dive profile transfer.

Usage and limitations: a dykdator is a tool that supports safe diving practices but does not replace training or prudent planning. Sensor accuracy, battery life, and algorithm choice can influence calculations, and devices require regular maintenance and calibration to remain reliable. Divers should understand their model’s settings and consider manual planning for dives that fall outside its typical use cases.
