What is the function of the dive tables?

The dive tables serve a crucial role in ensuring diver safety by providing a standardized way to determine safe dive profiles. They help divers establish the limits for depth and duration of their dives, taking into account the effects of pressure on the body and the time spent at various depths. By following these tables, divers can minimize the risk of decompression sickness, also known as "the bends," which occurs when a diver ascends too quickly after spending time at depth.

The tables outline dive times permissible for different depths, allowing divers to plan their dives effectively and safely. This planning also includes considerations for surface intervals and repeated dives, all aimed at managing nitrogen absorption and ensuring that divers remain within safe limits. Using dive tables is an essential practice for both new and experienced divers, reinforcing safe diving habits and fostering awareness of how various factors can influence dive safety.
