iDive DAN personal dive computer display showing decompression requirement and other data during a dive The central band shows time to surface from current depth, stop depth and stop time.
The dive computer eliminated the previously mandatory interconnected use of three pieces of equipment: diving watch (top right), depth gauge (bottom right) and waterproof decompression table (left).

To prevent or minimize decompression sickness, divers must properly plan, conduct, and monitor decompression. Divers follow a decompression model to allow the release of excess inert gases dissolved i

…profile data in real time. Most dive computers use real-time ambient pressure input to a decompression algorithm to indicate the remaining time to the no-stop limit, and after that has passed, the minimum decompression required to surface with an acceptable risk of decompression sickness. Several algorithms have…
