What is the first step in conducting a buoyancy weight check?

The first step in conducting a buoyancy weight check involves relaxing in a vertical position. When divers are in a vertical position, they can better assess their inherent buoyancy without the influence of other factors like tank pressure or gear adjustments. This position allows divers to accurately determine how much weight they need by observing their buoyancy state as they either float or sink. By relaxing and allowing their body to find its natural buoyancy, divers can ensure they have the appropriate amount of weight for effective control while diving, ultimately contributing to safety and comfort underwater.

In contrast, adjusting tank pressure, sinking to the ocean floor, or inflating the BCD fully do not initiate the weight check process. Before making further adjustments to equipment or weights, it’s essential to understand buoyancy in a neutral, relaxed posture. This sets a solid foundation for achieving optimal buoyancy control during a dive.
