Dive Site Hazards

Situational Awareness Loss — Divers may fixate on sharks and lose depth or position awareness.
Subtle Behavioural Shifts — Changes in shark behaviour may be missed without active observation.
Blue-Water Reference Loss — Lack of visual references increases ascent and descent instability.

Hidden Depth Variations — Complex reef topography can conceal depth changes, leading to unintended profile variations.

Distraction from Marine Activity — High fish activity can distract divers and delay depth or gas awareness.

Rapid Surge Direction Changes — Surge near reef structures can reverse direction quickly, pushing divers sideways into unexpected areas.
