In what current must extra weight be added when diving with an MK20 in open water?

When diving with an MK20 in open water, it is important to consider the influence of current on buoyancy and stability. Adding extra weight is critical when diving in currents that exceed 1.5 knots. This is due to the fact that stronger currents can create more drag on the diver, resulting in a potential loss of buoyancy control.

By adding extra weight, divers enhance their ability to stay submerged and maneuver effectively in challenging conditions. If the current is too strong and not enough weight is applied, divers may struggle to maintain depth or may become excessively buoyant, which can lead to safety issues. Therefore, adding weight in currents greater than 1.5 knots ensures divers can effectively manage their position and remain safe during their dives.
