The skiff slips off a low jetty and the island peels away: coconut palms, a patchwork of seaweed farms, and the reef rim that has lured divers for decades. Salt presses at your nose as instructors run through signals on the foredeck, and the ocean ahead seems to dare you to breathe differently.

Bring reef‑safe sunscreen
Use mineral-based sunscreen to protect coral—crews may ask you to reapply before entering water.
Hydration & rest
Drink water and get a good night’s sleep before surface intervals and dives to reduce risk of decompression stress.
Practice ear equalization
Work on gentle equalization techniques before training to ease discomfort during descent in open water.
Book dry-season dates if possible
Calmer seas in April–October give more reliable conditions for skill practice and longer surface intervals.
Mask & snorkel
A well-fitting mask speeds skill practice and conserves energy during surface swims.
Dive logbook or notebook
Record skills, air use and dive profiles for certification and future reference.
Dive computer or timing device
Helps monitor bottom time and ascent rates; some centers provide one but bringing your own is useful.
Reef‑safe sunscreen & rashguard
Protects skin from sun and reduces chemical impact on coral during surface and shore entries.
