Determining the appropriate ballast during unassisted aquatic descent involves achieving neutral buoyancy at a specific depth. The aim is to ensure the diver neither sinks nor floats effortlessly at approximately 10 meters, facilitating streamlined movement through the water column. An example would be adjusting weight until a diver can comfortably hold position at this depth without significant effort.
Correct weighting is crucial for optimizing performance and minimizing energy expenditure during dives. It enhances streamlining, reduces drag, and allows for more efficient propulsion. Historically, improper weight selection has led to increased risk of ascent difficulty and inefficient dives, highlighting the importance of meticulous ballast adjustment.
