Why should I not turn off a dive computer between dives?
Don’t turn your computer off between dives. Most won’t let you, but if you take out the battery or shut the computer down, it loses its memory of your previous dives and your residual nitrogen. You’ll have to allow all residual nitrogen to leave your body before resuming use of the computer. If you exceed your limits, you’ll have to make an emergency decompression stop. Your computer should go into emergency mode and let you know what depth you need to go to, and how long you need to stay there to off-gas safely before you can ascend to the surface.
