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.
Landmark Misidentification — Familiar sites can become unrecognisable at night.
Light-Induced Tunnel Vision — Focused light beams reduce peripheral awareness.
Depth Perception Errors — Reduced ambient light increases depth perception mistakes.
