Dive Site Hazards

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.

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.
