Dive Site Hazards

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.

Bubble Trapping Under Overhangs — Rock overhangs can trap exhaled bubbles, reducing visibility and causing disorientation.

Reflected Surge Patterns — Surge reflecting off rock faces can create irregular and unpredictable water movement.

Current Funnel Effect — Narrow gaps between rocks can accelerate water flow unexpectedly.

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.
