Which statement about weight systems is correct?

• A. The ability to quickly and reliably jettison at least enough weight to make the wearer positively buoyant at the surface or at depth.
• B. The ability to carry a minimum of at least 25 kg/55 lbs of weight.
• C. The ability to easily adjust the amount of weight used.
• D. Both the first and third answers are correct.

Answer: (A)

The key idea here is safety through buoyancy control. A weight system should let a diver shed ballast quickly and reliably so they become positively buoyant, enabling a safe ascent to the surface. This capability is essential whether you’re near the surface or deeper, because changes in gas volume (from breathing, depth, or ascent) can make you more negatively buoyant, and you need to be able to dump enough weight to rise rather than struggle underwater. Having a quick, dependable way to release weight directly supports a controlled, safe ascent in emergencies. While being able to adjust how much weight you’re carrying is practical and common, and there’s no universal minimum weight requirement across all setups, the defining safety feature is the ability to jettison enough weight quickly to achieve positive buoyancy.
