How does one maintain proper weighting for diving?

Maintaining proper weighting for diving is essential for safety and enjoyment underwater, as it allows a diver to achieve and maintain neutral buoyancy. By adjusting weights to achieve neutral buoyancy, a diver can float effortlessly in the water without needing to exert much effort to stay at a desired depth. This balance is crucial for both maintaining spatial awareness and minimizing energy expenditure, allowing divers to concentrate on their surroundings, conserve air, and have a more pleasant diving experience.

When divers are properly weighted, they should sink slowly and comfortably at the surface, and once they reach their desired depth, they should neither sink nor float, but instead hover with little to no effort. This also aids in avoiding issues such as rapid descents or ascents, which can be dangerous.

The other options do not effectively contribute to achieving proper weighting. Solely adding lead weights may lead to over-weighting, which can create problems with buoyancy control. Relying on a fishing line does not provide any functional assistance in determining or adjusting one's buoyancy in the water. Using a heavier wetsuit may contribute to additional buoyancy but does not appropriately address the need for individualized weight adjustments that can vary based on body composition, exposure protection, equipment carried, and other factors influencing buoyancy.
