Sunlight slices through the shallows off Koh Tao as you step off a small dive boat and feel the sea tug at your ankles — the island’s reefs waiting like a different country beneath the surface. The Private Basic Diver course condenses an entire first taste of scuba into a single, personalized day: a morning theory session, gear familiarization, then two supervised open-water dives in shallow coral gardens.

Hydrate and eat light
Drink water before arriving and have a light, carb-based meal; heavy meals can aggravate seasickness and buoyancy control.
Practice ear equalization
Swallow, valsalva gently, and descend slowly — early equalization prevents discomfort during shallow training dives.
Use reef-safe sunscreen
Apply mineral-based sunscreen and cover up with a rashguard to protect reefs from chemical runoff.
Bring a small waterproof bag
Keep passport copy, phone, and seasickness meds dry and organized for boat transfers.
Well-fitting swimwear & rashguard
Worn under a wetsuit to protect from sun and chafing during dives.

Light travel towel
Quick-dry towel for post-dive comfort on the boat and at the pier.
