What does the signal of a hand held to the ear by a Rescue Swimmer (RS) indicate?

The signal of a hand held to the ear by a Rescue Swimmer (RS) specifically indicates a need to deploy a radio. This gesture suggests that the swimmer is either requesting communication equipment to convey information or establish contact with those coordinating the rescue operation.

The purpose of this signal is to enhance communication during rescue missions, ensuring that the Rescue Swimmer can relay important updates, coordinate with support personnel, or receive instructions. Effective communication is critical in rescue scenarios where time and clarity can significantly influence the safety of both the swimmer and the individuals being rescued.

In contrast, the other options suggest different levels of urgency or actions: needing assistance typically involves clear signaling or distress signals, deploying a raft is usually a physical action taken in specific situations rather than a communication signal, and being ready for pickup is generally indicated by different, more active gestures or signals. Each of these has distinct meanings and contexts that do not align with the specific gesture of holding a hand to the ear.
