When should weights be ditched in an emergency situation?

In an emergency situation while diving, the decision to ditch weights is critical for ensuring safety and preventing potential drowning. The correct choice emphasizes that weights should be ditched when ascending.

When a diver experiences a situation that necessitates a rapid ascent, such as an emergency, retaining weights can hinder buoyancy control, thereby increasing the risk of descending too quickly or becoming negatively buoyant. In cases of an emergency ascent, such as needing to surface to avoid a dangerous situation or to access emergency oxygen, releasing the weights allows the diver to gain positive buoyancy. This action significantly increases the chances of a safe and controlled ascent to the surface where the diver can seek help or recover.

While loss of visibility, excessive air loss, or awaiting instructions could pose serious challenges, the act of ditching weights is specifically aligned with the immediate need for ascension. Therefore, understanding the correct timing and reasoning behind ditching weights is crucial for ensuring safety during underwater emergencies.
