What is the purpose of the dive table in dive planning?

The primary purpose of the dive table in dive planning is to help determine safe limits for depth and time. Dive tables provide essential information such as no-decompression limits, which indicate the maximum time a diver can spend at a specific depth without needing to perform mandatory decompression stops during ascent. By using the dive table, divers can effectively plan their dives to ensure safety regarding nitrogen absorption and the risk of decompression sickness.

Understanding the relationship between depth and time is critical for maintaining safe diving practices. It ensures divers stay within the limits that their body can safely manage, considering factors like depth and the duration of exposure to pressure. This knowledge allows for responsible and safe diving experiences, maximizing enjoyment while minimizing potential risks. Other choices may involve aspects of diving, but do not pertain directly to the dive table's primary function in ensuring safe dive practices.
