Weights should be placed according to what consideration?

The correct answer underlines the importance of determining the diver's needs while in the water. Adjusting weights according to the diver's specific requirements ensures that they achieve optimal buoyancy and stability during a dive. Each diver's body composition, gear configuration, and the type of dive being conducted can significantly influence how much weight is needed and where it should be placed for maximum comfort and effectiveness.

Considering the diver's needs in water allows for a practical evaluation of how weighted the diver feels, which can differ from surface conditions due to changes in water density and buoyancy effects. Proper weight distribution can also enhance control and minimize exhaustion, allowing for a more enjoyable and safer diving experience.

This approach recognizes that while suit type, personal preferences, and dive plans may contribute to weight decisions, they should ultimately serve the individual diver's needs as determined by actual conditions in the water for the best performance and safety.
