68.22kmLandmark 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.
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.
