If a diver feels a mild current at the start of a dive, what should they do?

Beginning the dive against or into the current is a proactive strategy to ensure that the diver doesn't get swept away from their intended dive site. Starting the dive while swimming against the current allows the diver to establish a sense of control and familiarity with the underwater environment, as well as provide an easier return to the starting point later in the dive.

When a diver swims into the current initially, they can gauge their strength and adapt their movements and breathing as needed. Once they have completed their exploration, they can return with the current, making the exit from the water easier and less strenuous. This method also minimizes the chance of becoming disoriented or running out of air while fighting against the current on the return.

Choosing to swim with the current at the start could lead to difficulties in navigating back to the entry point once the dive is completed. Waiting for the current to calm is often unpredictable and can result in wasted dive time or missed opportunities for exploration. Signaling for a change in location might be unnecessary if the current is manageable, as divers can usually acclimate to mild currents without needing to relocate.
