Which of the following statements is true about a dive computer?

A dive computer functions on a theoretical basis similar to that of dive tables, which are used to calculate no-decompression limits and to prevent decompression sickness during repeated dives. Both dive computers and dive tables utilize algorithms to track the nitrogen absorption in the body as a diver descends and ascends.

While dive tables provide preset calculations based on depth and time, dive computers dynamically calculate this information in real-time. They take into account factors such as your dive profile, rate of ascent, and surface interval, allowing for more personalized and precise management of dive limits based on recent dives. This adaptability means that they are able to provide a more accurate reflection of a diver’s current no-decompression limits.

The options regarding sharing a dive computer, maximum dive time, and the effects of dive depth do not accurately reflect safety protocols or the functionality of dive computers. It is recommended that divers use their own dive computers to ensure accurate personal data tracking, and dive computers have specific limits based on depth and time which are essential for safety. Thus, B is the accurate statement regarding dive computers.
