Which method can help with navigation during low visibility?

Following the light is the correct method to help with navigation during low visibility. In situations where visibility is compromised, such as in smoke-filled environments or during heavy rain, a reliable source of light serves as a guide to navigate safely. This method allows individuals to maintain orientation and avoid obstacles that may not be easily detectable in low visibility conditions.

Using a light source can also enhance communication and coordination among team members, as it provides a focal point that can be seen from a distance. In contrast, relying solely on sound, such as calling out for help or following team members without visual cues, may not be effective, as these methods can lead to disorientation in an environment where visibility is severely limited.

Additionally, the technique of "smooth bump bump to the pump" does not specifically address the challenge of navigation but rather describes a coordinated action typically used in equipment handling. Overall, maintaining visual awareness and using available light sources is vital for safe navigation in low visibility scenarios.
