What is the first thing you should signal to your buddy who is struggling against a current?

The first thing to signal to a buddy who is struggling against a current is to stop and hold on to a stationary object. This response is crucial because it allows the diver to stabilize themselves and regain control amidst the challenging environment of the current. By anchoring themselves to a stationary object, the buddy can conserve energy and assess their situation without the added stress of fighting against the current.

In a struggle, movement can often exacerbate the situation, leading to fatigue or panic. Holding onto a stationary object provides a safe refuge and allows for better communication and coordination. Once the buddy has regained composure and evaluated the scenario, they can then consider further actions like ascending or navigating to safety.

Taking immediate evasive action without stabilizing first, such as ascending or quickly trying to navigate, may not only increase the risk of injury or disorientation but may also lead to more challenging situations. Therefore, stopping and holding on is a sound strategy for safety and recovery in a strong current.
