All4Diving Phuket

All4Diving runs out of Patong and built its reputation on being the go-to shop for non-English speakers on the island. Course materials and in-water instruction are routinely delivered in German, French, Dutch, English and Thai depending on which instructors are rostered that week — worth a quick email before booking if a specific language matters to you.

Day trips run to the usual Phuket sites: Racha Yai, Racha Noi, Shark Point and the King Cruiser wreck, plus three-dive Phi Phi trips. Course volume is steady rather than huge, which keeps group sizes manageable without the price premium of a true boutique. Suits divers who want to train or fundive in their own language without paying private rates. Less suited to people set on the smallest possible groups or wanting a quiet base away from Patong nightlife.
