Dive computers provide the advantage of giving divers what type of credit?

Dive computers are designed to continuously monitor a diver's depth and time while underwater. One of their key advantages is the ability to calculate and record the various phases of a dive, including time spent at different depths.

When it comes to the credit for the shallow portions of the dive, dive computers take into account the time accumulated while operating at shallower depths. This aspect is crucial because it helps divers understand how that time may impact their no-decompression limits and overall dive profile. Shallow portions of a dive can be less taxing on the body in terms of nitrogen absorption, so having a calculation of this time affects the diver's safety and planning for future dives.

By accurately crediting the diver for shallow portions, the computer ensures that the diver has a comprehensive understanding of the dive, which informs safe ascent rates and necessary safety stops, ultimately contributing to a safer diving experience.
