What information do dive tables provide for divers?

Dive tables are essential tools for divers as they provide crucial information regarding no-decompression limits and safe ascent profiles. No-decompression limits indicate the maximum time a diver can spend at a given depth without requiring mandatory decompression stops during ascent. This is very important for avoiding decompression sickness, commonly known as "the bends," which can occur if a diver ascends too quickly or remains underwater for too long at certain depths.

Additionally, dive tables outline safe ascent profiles, which help divers plan their ascent to the surface in a controlled manner. Following these profiles minimizes the risks associated with rapid ascent and allows for adequate decompression if required. This careful planning is vital for ensuring the safety of divers during their underwater excursions, making dive tables an indispensable resource for both recreational and professional divers.
