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.

  • 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.

  • Gradual Narcosis Onset — Narcosis may develop slowly, making self-assessment unreliable.

  • Task Fixation at Depth — Cognitive narrowing at depth can reduce awareness of time and ascent rate.

  • Increased Gas Density Breathing Load — Higher gas density at depth increases work of breathing.
