What is the best practice in managing buoyancy in a dry suit?

Managing buoyancy effectively in a dry suit is crucial for safe diving. Frequent adjustments of air is the best practice because the air inside the dry suit serves as both insulation and a buoyancy control mechanism. As divers descend, pressure increases, compressing the air in the suit and reducing its buoyancy. To counteract this, divers should add air to the suit as needed to maintain neutral buoyancy.

Regularly adjusting the air allows divers to respond dynamically to depth changes, which is particularly important when ascending or descending, ensuring they can maintain control over their buoyancy throughout the dive. This practice helps prevent issues such as rapid ascents or descents due to fluctuating buoyancy, thereby enhancing safety.

Other approaches such as constantly adding weight would compromise buoyancy control, remaining at the surface limits the benefits of diving, and swimming with resistance can disrupt buoyancy management, making it harder to maintain stability in the water.
