Dive Site Hazards

  • 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.

  • 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.
