Dive Site Hazards

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.

Eddy Pull-Off Zones — Eddies behind structures can pull divers away from the main drift line.

Delayed Surface Pickup — Strong current can exceed surface tracking assumptions, delaying boat pickup.

Vertical Current Shear — Currents may vary by depth, causing vertical separation even when divers stay together.

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.
