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.

Deceptive Entry Openings — Openings may become restrictive inside due to angle, collapse, or corrosion.

Surge-Induced Internal Silt Shift — Internal surge can move silt and debris without direct contact.

Partial Overhead Environment — Many wrecks limit direct ascent even without full penetration.

Fine Rust Particle Silt-Out — Disturbed rust particles can rapidly reduce visibility.
