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.
