The sea opens in a blue arc as the boat eases off Koh Samui’s pier; salt stings the air and the deck hums with the quiet focus of divers going through gear checks. On this two-day PADI Advanced Open Water course you trade the island’s palm-lined beaches for the constant motion of tides, a navigation compass in one hand and new skills forming with each descent.

Bring your certification and logbook

Plan post-dive flights
Avoid flying within 18 hours after your final dive to reduce decompression risk—book return flights accordingly.
Hydrate and eat light between dives
Tropical conditions and exertion increase dehydration risk—drink water and choose light, carbohydrate-rich meals on the boat.
Practice buoyancy before deep dives
Good buoyancy reduces reef contact and conserves air—ask for a shallow refresher if you’re rusty.
Dive computer
Monitors depth and no-decompression limits—essential for deep and multiple dives.
Personal mask and snorkel
A well-fitted mask saves air and frustration during underwater navigation drills.
Reef-safe sunscreen
