How can a diver ensure control while ascending with current present?

Maintaining buoyancy control is essential for a diver, especially when ascending in the presence of a current. Effective buoyancy control allows a diver to adjust their depth and position in the water column, enabling them to counteract the force of the current. By using their buoyancy compensator device (BCD) properly, divers can add or release air to ascend or descend smoothly, avoiding rapid movements that could lead to negative consequences such as barotrauma or uncontrolled ascents.

When a diver is able to maintain neutral buoyancy, they can ascend at a safe and controlled rate, minimizing the risk of being swept away by the current. This control is crucial for safety during the ascent, as it helps the diver to stay aware of their surroundings and manage their ascent rate to prevent issues like decompression sickness.

Other options, while related to diving safety, do not directly address control during ascent in currents as effectively as buoyancy control does. For instance, descent speed pertains more to controlled descents rather than ascents, and while proper weighting is important for overall buoyancy, it doesn’t provide the direct control during ascent that buoyancy adjustments do. A dive knife can be a useful tool for safety but does not play a role in controlling buoyancy
