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.

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.
