What is often required in dry suit diving to account for increased buoyancy?

In dry suit diving, increased buoyancy is a common challenge due to the air trapped within the suit and the insulation properties of the materials used. When wearing a dry suit, divers need to consider the additional buoyancy that the suit provides, which is primarily caused by the volume of air it contains.

To counteract this buoyancy and maintain neutral buoyancy underwater, divers typically need to carry more lead weights than they would when diving in a wetsuit or no suit at all. This added weight compensates for the buoyancy of the suit, allowing the diver to descend and remain submerged without difficulty.

In contrast, other options suggest using less weight or large weights, which may not effectively balance the increased buoyancy of the suit. Carrying more air in the suit may also increase buoyancy rather than counteract it. Therefore, the appropriate answer focuses on the necessity for additional lead to offset the dry suit's buoyant characteristics.
