What is the primary goal of using dive tables?

The primary goal of using dive tables is to plan non-decompression limits and safety stops. Dive tables provide divers with critical information regarding how long they can stay underwater at specific depths without exceeding safe levels of nitrogen absorption. They help in preventing decompression sickness, which can occur if a diver ascends too quickly after spending time at depth.

By using dive tables, divers can establish dive profiles that include safe ascent times and required safety stops, which are breaks taken at certain depths during ascent to allow for nitrogen to safely leave the body. This planning is essential for ensuring the diver's safety as it helps manage the risks associated with diving.

While monitoring buoyancy control, establishing underwater communication, and calculating water currents are important aspects of diving, they are not the primary purpose of dive tables. The focus of dive tables is specifically on managing exposure to pressure and nitrogen, which is critical for safe diving practices.
