Not satisfied with 30 metres? Want to see what's at the bottom of Chumphon Pinnacle, or dive the MV Trident? Then you need the Deep Specialty. Over 2 days I teach you the procedures and safety precautions to safely dive to 40 metres, the limit of recreational diving. You'll see how depth affects light, pressure-sensitive items, and experience nitrogen narcosis. Experience of deep diving is also a prerequisite for your journey into Tec Diving.

Schedule: 2 days.

Dives: 4.
