What is the first part of the pre-dive procedure?

The first part of the pre-dive procedure is the environmental evaluation. This step is crucial because it involves assessing the conditions in which the dive will take place, such as water temperature, visibility, weather conditions, and potential hazards like currents or marine life. By evaluating the environment, divers can make informed decisions about the dive site, understand what to expect during the dive, and adjust their plans accordingly to ensure safety.

Conducting an environmental evaluation helps divers prepare not only for their immediate surroundings but also to anticipate any challenges they may face underwater. This step sets the foundation for creating a comprehensive dive plan that takes into account the specific conditions of the dive location. Having an understanding of the environment allows divers to adjust their equipment, gas mixtures, and overall dive strategy to manage risks effectively.

While equipment checks, dive plan overviews, and buddy checks are all important components of the pre-dive procedure, they build upon the understanding gained from the environmental evaluation. It is essential to know the conditions before proceeding with planning how to dive safely.
