Which scanning pattern is effective for lifeguards?

The scanning pattern that is most effective for lifeguards is scanning the water from bottom up. This method allows lifeguards to thoroughly observe the entire water column and identify any potential issues, such as individuals in distress at various depths. By starting from the bottom and moving upwards, lifeguards can catch reflections, movement, or signs of distress that might otherwise be missed if they were only looking at the surface.

This approach also aids in detecting submerged objects or swimmers who may not be immediately visible on the surface. Efficient scanning techniques enable lifeguards to maintain vigilance over a larger area, ensuring that they can quickly react to emergencies while maximizing their situational awareness. Additionally, this method encourages a systematic review of the environment, promoting a more thorough monitoring process.
