Overweighting
Definition
Overweighting refers to carrying more lead weight than necessary when scuba diving, which can negatively affect buoyancy control and safety.
More on Overweighting
Overweighting is a common mistake among beginner divers who fear not being able to descend. While a small amount of extra weight can aid descent, excessive lead hinders buoyancy control, increases air consumption, and can result in rapid descents or poor trim. Divers should perform a proper weight check at the surface and re-evaluate their weighting when switching gear, exposure suits, or diving in different water salinities (saltwater vs. freshwater). Proper weighting contributes to more relaxed, efficient, and safer dives.
Frequently Asked Questions
Excess weight makes it harder to control ascent speed, increases air consumption, and can force divers to inflate their BCD too much, leading to unstable buoyancy.
If you struggle to stay neutrally buoyant, sink too quickly, or must use excessive BCD inflation, you may be carrying too much lead.
Not necessarily. Weight helps with descent, but proper buoyancy and streamlining are more important for control in currents.
Float at eye level with an empty BCD and hold a normal breath. You should sink slowly when exhaling. Adjust weights accordingly.
Yes. Thicker suits provide more buoyancy and require more weight. Always re-check when changing exposure protection.
