What is the benefit of having additional weights during a deep dive?

Having additional weights during a deep dive primarily aids in weight distribution, which is essential for maintaining proper buoyancy control. When diving at greater depths, the increase in water pressure can affect buoyancy, making it necessary to adjust your weighting. Proper weight distribution ensures that you are neither too buoyant nor negatively buoyant, allowing for a more stable and controlled descent and ascent.

In deep diving scenarios, divers may use additional weights to counteract buoyancy from wetsuits or any trapped air in gear, which can vary with depth. Well-distributed weights will help the diver maintain an optimal position in the water column, promoting efficient movement and energy conservation.

The other choices, while linked to various aspects of diving, do not directly capture the primary benefit of extra weights in a deep diving context.
