Should a diver always put their weights in one system?

The idea behind distributing weights in a dive is rooted in a diver's comfort, buoyancy, and safety. Placing all weights in one system, such as a weight belt or integrated weight system, can create an imbalance. This imbalance can lead to difficulties in controlling buoyancy, particularly during ascent and descent, and may hinder a diver's ability to achieve the desired trim, which is critical for efficient movement underwater.

Distributing weights allows for better weight distribution across the body, which can enhance overall comfort and stability. This method can help in maintaining a more streamlined position and reduce drag, making underwater movements easier and more efficient. Furthermore, should an emergency situation arise where a diver needs to ditch weights, having them spread across different systems can provide flexibility and safety.

The context of the other options helps to highlight the principle. While certain diving scenarios might warrant specific weight setups, the general guideline is to avoid placing all weights in one system to better manage buoyancy and overall performance underwater.
