What is the night hand signal to move in for pickup?

The night hand signal for moving in for pickup involves waving a chem light. This method is particularly effective in low-light or nocturnal environments as it provides a visible indicator that can be easily recognized from a distance. Chem lights can produce a bright, distinguishable color that stands out against the darkness, making it clear to rescuers that the swimmer is ready to be picked up. This form of communication is crucial in rescue operations where visibility is limited and time is of the essence.

Using a waving motion captures attention and conveys urgency while ensuring the rescue team can triangulate the swimmer's position in the water. The effectiveness of a chem light is enhanced due to its portability and ability to be activated quickly, providing immediate feedback to the crew performing the rescue.

In contrast, other suggested signals may not communicate the same level of clarity or urgency in a nighttime scenario, which is why the chem light is preferred.
