Start early for best visibility
Morning dives usually have calmer seas and better visibility for skills and wreck approaches.
Bring a personal mask
A well-fit mask improves comfort during confined-water drills and reduces fogging on repeated skill practices.
Reef etiquette matters
Keep neutral buoyancy and avoid touching coral—training emphasizes reef protection alongside skills.
Hydrate between sessions
Tropical heat and repeated dives demand consistent fluid intake; carry a refillable bottle.
Personal mask and snorkel
A well-fitting mask improves comfort and visibility during confined-water practice.
Shorty or full wetsuit (3–5mm)
Thermal protection for early mornings and longer surface intervals in tropical waters.
Dive computer or depth gauge
Useful for tracking depth and no-decompression limits during open water dives.
Reef-safe sunscreen
Protects skin from sun and minimizes harm to coral and marine life.
