What is a dive table used for?

A dive table is a critical tool used by scuba divers to determine no-decompression limits and to establish safe ascent rates based on the depth and duration of their dive. It provides vital information that helps divers avoid decompression sickness by indicating the maximum time they can spend at various depths without requiring mandatory decompression stops during ascent. By adhering to the limits set by the dive table, divers can ensure their safety and minimize the risks associated with ascending too quickly or exceeding no-decompression limits.

Planning dive equipment checks, logging dive locations, and establishing physical fitness levels for divers are all important aspects of diving, but they are not the primary function of a dive table. The dive table specifically addresses how to manage the physiological impacts of diving, making it essential for safe diving practices. Understanding these functions is crucial for anyone training to be a Divemaster, as it directly affects the safety and well-being of divers during their activities underwater.
