Core Specialty
Night & Limited Visibility Diving
The reef at night is a different world. Predators hunt. Invertebrates emerge. Coral polyps open. The Night & Limited Visibility Specialty teaches you to navigate, communicate and enjoy these conditions safely — with torches, good technique and genuine awareness.

Skills and Knowledge
Managing Darkness Underwater
Night diving removes the visual context you normally rely on for orientation and buddy awareness. The course teaches you to replace those cues deliberately — with light signals, contact procedures and a slowed, methodical approach to every movement.
- Torch use — primary illumination, signalling and backup light procedures
- Buddy contact — maintaining awareness of your partner in low visibility
- Navigation — using natural references and compass in reduced light
- Entry and exit — managing boat and shore entries safely in darkness
- Marine life — safe and respectful interaction with nocturnal species
