Dive Site Hazards

  • Landmark Misidentification — Familiar sites can become unrecognisable at night.

  • Light-Induced Tunnel Vision — Focused light beams reduce peripheral awareness.

  • Depth Perception Errors — Reduced ambient light increases depth perception mistakes.

  • 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.
