What is a common practice before embarking on a deep dive?

Initiating a slow and considered descent is a vital practice before embarking on a deep dive. This approach allows divers to equalize pressure in their ears and sinuses gradually, minimizing the risk of barotrauma. A slow descent also enables divers to monitor their buoyancy closely and maintain better control of their descent rate, reducing the chances of unnecessary rapid ascents that could lead to decompression sickness.

By taking the time to descend slowly, divers can also observe any changes in their environment, such as marine life or potential hazards, thus enhancing their situational awareness. This careful approach is crucial for safety and helps ensure that divers can manage their air supply effectively while preparing for deeper underwater conditions.
