What is the most urgent risk area to look at when scanning 3-dimensionally?

When scanning 3-dimensionally as a lifeguard, the most urgent risk area to focus on is the bottom of the pool. This area is critical because it’s where individuals, especially those who may be struggling or at risk of drowning, can go unnoticed if a lifeguard's attention is directed elsewhere.

Individuals submerged or struggling at the bottom are harder to spot than those on the surface because they may not be able to signal for help. The bottom often presents a danger, particularly in deeper areas, where someone may be unable to surface due to fatigue or disorientation.

Focusing on the bottom allows a lifeguard to ensure the safety of all patrons, especially those who may be at risk due to lack of swimming skills or those who might be trapped or having difficulty. This proactive scanning helps prevent accidents before they escalate. Meanwhile, while edges, shallow ends, and entry points are important to monitor, they do not carry the same level of immediate risk in drowning scenarios as the bottom of the pool does.
