Dive Site Hazards

  • Unstable Visual Ascents — Relying on wall visuals can destabilise ascents.

  • Gradual Depth Creep — Lack of visual bottom reference can cause unnoticed descent.

  • Unsignalled Downcurrents — Downcurrents can form without visible indicators.

  • Remote Silt Disturbance — Silt can be disturbed metres away from the source.

  • Rapid Stress Escalation — Stress can increase sharply when visibility or navigation degrades.

  • High Cognitive Load Navigation — Complex passages increase mental workload even on a line.

  • 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.
