What is the primary function of a dive table?

The primary function of a dive table is to calculate safe ascent times and decompression stops. Dive tables are integral to dive planning and safety as they provide divers with critical information about how long they can remain at specific depths and how long they need to stay at certain depths during ascent to allow for safe decompression. This is essential to prevent decompression sickness, also known as "the bends," which can occur if a diver ascends too quickly and nitrogen bubbles form in the body tissues.

Using these tables, divers can look up their planned maximum depth and the duration of their dive to determine the necessary ascent rate and any required stops along the way. This systematic approach to managing decompression minimizes risk and enhances the overall safety of the diving experience.
