Why should a diver avoid turning off their dive computer between dives?

A dive computer is specifically designed to track various parameters of your dive, including depth, time, and water temperature, and it calculates your no-decompression limits and surface intervals based on this data. If a diver turns off the device between dives, it can lose essential information about the previous dive, which is crucial for safe planning of the subsequent dives.

The dive computer relies on the data collected to maintain an accurate assessment of nitrogen absorption in the body during repeated dives. By losing this memory, the diver may be unaware of how much nitrogen is still in their system, which can increase the risk of decompression sickness.

Maintaining the dive computer in an active state keeps it ready to continue monitoring your dive profile and ensures that it uses all gathered information for future dives, promoting safer diving practices and reducing the likelihood of dive-related injuries.
